Chevy Silverado Problems

caugusta

Thanks for the feedback guys. GM's policy is they will not cover a rental for the first day. the vehicle must be held overnight for them to pay. The dealer I brought it to for service is not the dealer I bought it from.

It seems that the transmission downshifts at faster speeds than it should. We all have probably had a standard in the past. with a standard, I do not downshift at all. I slow down in top gear (5th) until about 20 mph, then into neutral and use the brakes.

This truck downshifts from 3rd to 2nd around 15 or so. Why can't they make it downshift into 2nd at 5-10? It upshifts 1st to 2nd at 5-10. This is the 1st vehicle I've purchased new with an auto. I figure this time I'll stick with GM since the've been making them for 50 odd years. But NO; it shifts like other GMs I've had for a few thousand bucks with 100k miles.

Why? And my back and neck can't stand these horrible seats. I had a VW Fox a couple of years ago that cost me $400. With headrests that PIVOT FORWARD!!! When are these American auto mfgrs going to sit in a German car and note the comfort!

Ford driving tomorrow. And if that's no good, new BMW 3 series and $4k long bed 120k mile work truck. I only need the truck since I bought a house and need to Home Depot it.

They found a fix for the launch shudder...

Isnt it funny how to one person these seats are great and uncomfy for another.

To me i love em very comfortable. Even my grandfather who has driven camrys for the past decade and a half said and i quote "these seats are more comfortable than my lazyboy" trust me he is hard to please i was shocked when he said that.

GOOD LUCK CAU

I find the 40/20/40 seat extremely comfortable. I drove an Astro the other day and it had captain's chairs that were awful. The fold-down armrest was way too close to me for me to be able to rest my arm on it. With my center seat-back folded down I have an incredibly comfortable armrest. I also drove a Saab 9-5 the other day, but I still like my truck better.

Love my last two sets of vinyl bench seats, 1/2 ton Silverado and my 3/4 ton Sierra strippers. My buddies with leather and cloth are jealous!?!

jed1894

What?....... what kind of shaft?........ I got the one piece, but the "propeller" shaft....what's that?.... I knew it all-a-long....LOL......

tucsonjwt

I understand that if you get leather seats you also get a vinyl rear seat, and that only the "seating surfaces" are leather on the other seats. I know that northern AZ is not like Tucson, but is the new vinyl material you have as "sticky" and hot as the old style vinyl seats in the summer? I used to drive an 80s vintage S10 at work, and it would be a real butt burner in the summer. I'm considering a base Tahoe in my future, which only comes in vinyl. Marathon Seat Covers is supposed to make factory cloth seat covers, which might be an interesting option.

eddiebean

which plugs should I switch to for possible cure of minor rough idle on 2000 4.8 engine? Also has anyone installed the Edelbrock IAS shocks-if so how are they? Thanks

turner11

Has the problem been fixed or can it just not be heard any more due the insulation?

Could you provide more info on the Bob Prim fix? Has anyone else been able to resolve this noise in another way?

Launch Shudder On Acceleration (Install New One-Piece Propeller Shaft) #01-04-17-001
Launch Shudder On Acceleration (Install New One-Piece Propeller Shaft)
1999-2001 Chevrolet and GMC K2500/3500 Extended and Crew Cab Long Box Pickup Models

With Automatic Transmission

Condition
Some customers may comment on a vibration during acceleration from 0-40 km/h (0-25 mph). This may also be referred to as launch shudder. This condition may be more noticeable when the vehicle is carrying cargo or is used for towing.

Correction
A new propeller shaft is available for service to correct this condition. This new propeller shaft is a one-piece design and will replace the current two-piece design.

Install a new one-piece propeller shaft on affected vehicles. Refer to the service procedure and the parts information listed below. Match the affected vehicle with the appropriate propeller shaft. Refer to the usage information below. This fix does not apply to the Chassis/Crew Cab Models (K35943).

Place the transmission in the Neutral position.
Raise the vehicle. Refer to the Lifting and Jacking procedure in the General Information subsection of the Service Manual.
Remove the bolts and the yoke retainers from the rear axle pinion yoke.

Important
Do not pound on the propeller shaft yoke ears. Do not pry or place any tool between a yoke and a universal joint.

Slide the rear propeller shaft forward in order to remove the propeller shaft from the rear axle pinion yoke.
Remove the center bearing to the center bearing support nuts.
Remove the center bearing from the center bearing support.
Remove the front propeller shaft by sliding the front propeller shaft rearward from the transfer case.
Remove and discard any prior shims that may have been installed with the previous propeller shaft.


Important
The center bearing support bracket (1) must be removed in order to provide enough clearance for installation of the one-piece propeller shaft. Avoid damaging the crossmember during removal of the center bracket. For proper clearance, no more than 13 mm (½ in) of the bracket may remain on the crossmember after removal.

Remove the center bearing support bracket from the kick-up crossmember using a cut-off wheel.


Grind the rough edges smooth.
Coat the exposed metal surfaces (1) with frame coating using the information found in the applicable Service Manual and GM Refinish Material Booklet #4901M-D-2001 (English) or #4901M-D-F2001 (French).
Install the new propeller shaft by sliding the front of the propeller shaft into the transfer case.
Install the rear propeller shaft onto the rear axle pinion yoke.
Install the yoke retainers and the bolts. Tighten
Tighten the bolts to 25 N·m (19 lb ft).

Lower the vehicle.

Wonder if this fix would apply to the 1500 series 2WD low speed vibration. I took mine to the dealer for the brake line recall the other day, mentioned the vibration and they said the rear wheels (steel) were slightly bent. This was after the tires were balanced seven times by different dealers and the truck doesn't have 3000 miles yet. The BBB arb. turned down buyback in Jan. Because he felt if I took it back for another repair attempt ( #5 ) Chevy would fix it this time. A lawyer has the case now but haven't had any news in six weeks.

se32

This is my first time on here. I have a 1999 Silverado with a 5.3. I've had engine clatter and knock since I bought it. Has anyone else had this?

I'm currently in the final stages with the BBB and Chev. has their "Last and Final" attempt this Tuesday 4/20. I'm pursuing a replacement because I have 32K miles on the truck. My dealership, NorthPoint Chev. here in Alpharetta, GA has done nothing to help me or give me service with this engine clatter. They have told me that it's carbon build-up and piston slap. I told them that I did spend that kind of money on a vehicle to get a snare drum when I go down the road.

Anyone else got this problem and have you had it solved??

Regard,
One frustrated Chev owner! I think I'll buy a Ford PowerStroke next time!

ryanbab

hmmm 5.3 to a powerstroke?

Big difference there man

Has this engine noise caused the engine to quit working? Leave you stranded? (not including getting it worked on and inconveiencing you)

If you have 32K miles and no major problems than an engine noise whats the real problem? Not to sound like an A hole but if the truck hasnt broke down or the performance has seen a drastic decline is it a major problem?

obyone

Your clattering 5.3 and the Ford PS will sound about the same. Ford replaced the piston slapping 5.4. Will GM do the same? Not without their arms being twisted by the BBB or lemon law. On all the boards that I've frequented, haven't seen any resolution to your problem other than replacing the motor and/or the truck.

Don't pay attention to the post in between yours and mine cause if he had your problem, he would be trying to cut in line at the dealer to have his fixed before yours....LMFAO!

If my 5.3 sounded like a diesel, I would be the first in line to ask for a new motor or truck. Cause it's NOT supposed to be that way. Seems even Toyota is having the problem on their Tundras and Sequoias.

xbbuster

Would you have considered the Major Guard 6/100 $0 deductible? That way you could leave your truck at the dealership for the next 6 years or 100,000 miles and drive a nonvibrating loaner.(j/k)

On a serious note, I would give that attorney a call cause 6 weeks with no word is a bit long. In this type of case, the burden is on the buyer cause the manufacturer could actually care less as the longer you drive it, the more they will attempt to deduct. I am assuming that the attorney specializes in lemon law. Maybe you could print the tsb and give it to your dealer....Good luck...on this ongoing saga.

ryanbab

Obyone

Seems kinda strange that he would go from a 5.3 to a Powerstroke which makes a ton more noise and is a whole lot more of an engine. I think there is more to this story. Not just engine noise

se32

Ryanbab
Obviously you've got nothing better to do than gab. I entered this site for some serious feedback not noise. FYI Mr Shallow, my switch to a PowerStroke had nothing to do with the clatter. It simply had to do with quality.

Obyone
Thanks for the note. I will keep pursuing the BBB claim and untimately, if I have to, the Lemon Law. Georgia has a pretty liberal one and I know I've qualified.

All,
My reason for entering this discussion was to gain vital backup info for the BBB hearing with Chevrolet. I welcome anyone with serious feedback and resolutions they have obtained.

Regards,

caugusta

So do any of you guys have the problems with the transmission shifting rough? This is why I came to this town hall. I did see a couple of issues with the rough F to R or N to R issues but nothing to do with rough shifting transmissions.

To the seats guys,
I guess the seats are OK but I've owned 3 BMWs (two 5 series and a 7 series) and I'm used to seats of unsurpassed quality.

I also have a heating problem in my 2000 K3500 crew cab diesel. The passenger's side defrost temperature is at least 40 degrees, and up to 75 degrees colder than the driver's side. With the heat set anywhere between extreme hot and extreme cold, there is a large temperature difference between the driver's and passenger's side defrost. The difference gets larger the faster the vehicle is moving, and the colder it is outside. With the heat 1/2 way between hot and cold, travelling at 70mph on a 24 degree day, it will blow out 120 degrees on the driver's side, and 48 degrees on the passenger's side. It's been in the shop 5 times at different dealers. All have said the system is normal and acting similar to other vehicles tested.

We go to arbitration soon. As far as I can tell, only 3/4 and 1 ton trucks are affected. Not sure what model years - only 2000 as far as I know. This heating system (HVAC400) is used in all 1988 - 1998 1/2 ton trucks and all 1991 - 2000 3/4 and 1 ton trucks. The 1/2 ton trucks don't have this problem (my 1990 doesn't). Need more info on the 3/4 and 1 ton trucks.

Anyone else out there with a 3/4 or 1 ton late model truck that can check their system?

Sorry to hear about your problems with your '01.
I've had my '01 Silverado, 1500, LS, ext-cab, Z-71 for 3 months now.
So far I've got 2258 miles on it with absolutely no problems what-so-ever!
No rattles, no vibrations, no squeaks, no wind noise, no engine knocking, no clunking, and no sagging.
It is an absolute dream to drive, and very comfortable seating for me and the 5 other passengers I've taken on long drives 2 different times.
Lots of tire spinning power (lock diff) on dry pavement.
It was built on 12/6/00 in Ryan's home state at Ft. Wayne, Indiana.

Way to Go........Gonzaga!!!!
Sorry Ryan (Indiana State)

with 4.8 L or 5.3 L Engine (VINs V, T -- RPOs LR4, LM7)

and Hydra-Matic 4L60-E Transmission (RPO M30)

Condition
Some customers may comment about a harsh 1-2 upshift during acceleration at light to moderate throttle opening. It is characterized by a "Bump" at the end of the shift. A similar condition may exist during a "Power-on" 3-2 downshift.

Cause
Condition may be caused by insufficient line pressure to complete the shift caused by component variation.

I have a 98 K1500 Z71 with a 5.7 litre engine and 28000 miles on it and have a problem with gear oil flowing out from the front differential vent tube. After numerous trips for repair to a dealer, I can't seem to get this problem fixed. This truck is in
MINT condition and never been abused. It also seems to only do this in 2WD. Has
anybody experienced this problem? Also when shifting from 4HI to4Lo (as per owners manual) there seems to be a loud 'clunk noise' Is this normal for an electronic transfer case?? Any help would be greatly appreciated. Other than that,
this truck is awesome.

I took my 2000 Silverado with the 5.3 in for service recently because the gas pedal was sticking. It wasn't sticking when you were driving down the road, but it was hard to get moving when you first got in the truck. My service technician told me that my problem was a carbon buildup in the throttle body and it would have to be cleaned out. I thought it was odd, since my truck was barely a year old but I said to go ahead and clean it out. What he told me next was that this was a symptom of a larger problem. He recommended that I get my injectors flushed out because that was 'recommended maintenance' at 30000 miles. What really surprised me is that this service was not covered by warranty.

Has anybody else experienced this problem?

I've never heard of this happening before on any vehicles previous to the 2000 models. I was also told that it wasn't a problem with engine design but a problem with fuel quality. I beg to differ. I don't pull up to any of those hole-in-the-wall gas stations and I use the same gas as people who drive other types of cars but they aren't experiencing the same problem. After many communications with the dealer and Chevrolet's customer satisfaction people......or at least that's what they call themselves.....I have had no resolution to the problem. I was stuck paying for a repair bill that I felt wasn't my responsibility. I haven't gone to the BBB yet, but that's my next course of action. Any suggestions?

john294

how many miles are on your truck , have you used injector cleaner?I have 12k on my trk and havent noticed any carb problems yet ,just wondering if adding some inj.cleaner would be a preventive maintenance now instead of waiting for problems to arise....I get gas where-ever I happen to be when I need it....I went with the BBB with a problem with my new 2000 rado ,got one of their lame excuses and a extended warrenty out of GM,hopefully youll be able to gather more info here on line as I did that will help you decide.

mpfiguy

I have a 2000 Silver ado and it had the same problem you describe. I turned out to be the throttle body. Seems the shaft is supposed to be hardened but some were not. This causes the shaft to cut into the body and you end up with a sticky throttle. My dealer was aware of the problem and installed a new modified throttle body. Check with your dealer and tell them about this.

tucsonjwt

3000 miles. SES light came on. Went to the dealer(problem cleared up by then.) Dealer said there was a TSB on flushing the injectors.Dealer flushed injectors and replaced one that was not functioning under warranty. Dealer also put a bottle of Techron in the tank. All under TSB - no charge - covered by warranty (but only 3K on truck at the time.) I don't know if the TSB only applies to V6s. I put a bottle of Techron in the tank every 3K, and I only use Chevron gas with Techron. No problem since - now at 11K miles. I don't know if gas quality is an issue or not, but I am sticking to Chevron just in case - price around here is about the same, no matter what brand.
Good luck.

jed1894

I have the engine ticking noise on my 99 Silverado. With the help of BBB, I got a free extended warranty. I'll trade or sell the truck before the warranty expires so I'm not too concerned about the engine at this point.....no cure as far as I know. The dealers are putting out alot of BS about the problem......

JOhn

erikheiker

Chevron really ticked me off a year or so ago. Now I only use Texaco. I hope they have something similar to Techron in their gas! I heard that Chevron was going to buy Texaco, so I may be back with them again!

obyone

The throttle body is supposed to be replaced...not cleaned...not adjusted...replaced. As for your injectors, if they needed to be worked on, should be covered under warranty UNLESS the dealer can PROVE that it was fuel related.

TSB for throttle body....if anything, I would recommend going back to have your TB replaced as failure or sticking will eventually repeat itself.

Increased Accelerator Pedal Effort (Replace Throttle Body) #00-06-04-007B
Increased Accelerator Pedal Effort (Replace Throttle Body)
1999-2000 Chevrolet and GMC C/K Pickup Models (Silverado and Sierra)

with 4.8 L, 5.3 L or 6.0 L V8 Engine (VINs V, T, U -- RPOs LR4, LM7, LQ4)

This bulletin is being revised to include instructions on reading the Date Code, and added text on which Throttle Body Assemblies to replace. Please discard Corporate Bulletin Number 00-06-04-007A (Section 04 -- Engine Controls).

Condition
Some customers may comment on a higher than expected accelerator pedal effort from the idle position.

Cause
Condition may be caused by a tight throttle blade in the throttle body bore when in the closed position.

Correction

Notice
DO NOT adjust the shipping air screw to rotate the throttle body blade away from the throttle body bore. Adjusting the shipping air screw compromises the idle speed control, and may lead to other driveability concerns. Adjusting the shipping air screw may lead to reduced Idle Air Control valve durability.

Verify the cause for this condition is not a damaged or binding throttle cable.
FIGURE Figure 1 - Throttle Body Date Code Identification(c)




(1) Location of last 5 digits of Throttle Body Assembly Part Number
(2) Location of 4 digit Julian Date Code
(3) Throttle Body Assembly

Remove the throttle body (3) from the engine and inspect the 4 digit Julian date code (2) stamped on the bottom edge of the mounting flange. The Julian date code is stamped on the lower edge of the mounting flange, next to the gasket edge, on the side of the throttle position sensor. The stamped 5 digit code (1) is the last 5 digits of the Throttle Body Assembly Part Number. See Figure 1 - Throttle Body Date Code Identification.
If the Date Code is 2979 , or earlier (Indicating the Throttle Body was built before the 297th day of 1999):
DO NOT clean the Throttle Body Assembly.
Replace the Throttle Body Assembly using the Service Manual procedure.
DO NOT attempt to adjust Throttle Body Assemblies.

Notice
All 1999 models whose Throttle Body has not been replaced will have a date code prior to 2979 and should be replaced for this condition.

Reading The Date Code
The four digit Date Code can be interpreted as follows:

Example -- Date Code 2979

The first 3 digits (297) represent the calendar Julian date. 297 = the 297th day of the calendar year.
The last digit (9) represents the last digit of the year.
8 = the year 1998
9 = the year 1999
0 = the year 2000
1 = the year 2001

wight1

obyone and mpfiguy speak the truth. The throttle body should be replaced for the sticking/binding problem. I took my 6.0 in a couple of months back, and they swapped on a new TB, no questions asked.

Several other people have said their dealer told them the problem was due to carbon build-up (presumably from the EGR valve intake) and that this was a routine service (non-warranty) problem. No way.

punjab

My 01 Z-71 5.3 has about 4k on it, and I have started to notice that it only wants to downshift 1 gear when I stomp on the accelerator instead of the 2 gears it (and my 99 Z-71) was dropping. I came damn close to being T-boned the other day when the acceleration wasn't as anticipated...

Any similiar experiences?

jpals1

I have a question for the undisputed TSB King. What responsibility does your dealer have to inform you of TSB's? I have what sounds like the steering shaft problem, and have described it to service almost precisely in the words of the TSB - yet they come up with different (and ineffective) answers. I guess the bottom line is that I would like the service department to be aware of the TSB, bring it to my attention, and fix it. It is under warranty, after all. Is it my responsibility to bring in the TSB? Do other dealers work like this?

ryanbab

Do not have to inform public about TSB's.

They are given to the dealers from the company. They dont have to tell anyone because not everyone has the problem. If everyone did they would make it a recall and notify everyone. basically you have to do some digging online. Print out the TSB and take it to your service dept. That should convince them.

They wont replace your steering shaft? Sounds like you are getting the shaft. Mine rattled while going over bumps. The service foreman drove my truck twice for a total of about an hr. Could never duplicate the problem (and he couldnt he wasnt lying i drove the truck and he did it never rattled). Well he just decided to replace it anyways. Ill be damned but since then it hasnt rattled and i can tell it is fixed.

Good luck

(also maybe try another service dept they arent all the same there are good ones and there are bads ones)

I went to review the Chevy buy back discussions related to vibrations, but the postings are gone. Did Chevy take care of those consumers to keep them off the site? My 2000 Silverado 1500 extended cab is starting to exhibit what I believe is the same problem. I have 22k on it and have balanced and rotated the tires every 6k miles. Tires are Goodyear ATS. Problem is a vibration in the steering wheel from 65 mph on up. It's very noticeable when holding the steering wheel lightly with one hand. If you remove your hands slightly, the wheel vibrates left and right... seems to be getting worse. Also, had the extended door TSB done and that solved the closing problem. But now the doors are squeaking and a major air leak between the doors on the top left hand doors. Truck is in again to fix that and to try to eliminate the squeaks in the dash. It's driving me nuts as I live on a short gravel road and it squeaks constantly. Also still having problems with my drivetrain clunking in the rear-end at acceleration and when stopping. Major thunk/clunk when shifting between gears. Bottom line is that this truck is junk and I would not recommend a Silverado to anyone. If they don't fix it, I'm bypassing the regional service director and going right to the BBB, maybe they can get it straightened out.

obyone

The BBB can also help you with attaining a 6/100K $0 deductible extended warranty. Should at least give you some piece of mind for a little while. There are TSB's for every problem you've described except for the vibes at 65+. That's a new one.

jpals1

Yes, the dealer is under no obligation to notify you of TSB's, in fact, some will even argue that the TSB you're quoting cannot be found. Sometimes you have to wonder where they found these guys!

Product teams continually seek valuable information for product engineering improvements. An exchange program will be administered by GM Powertrain during the 2001 model year. The duration of the program is six months for the above applications. Guidelines for honoring exchange requests under the exchange program are being strictly enforced for the 2001 model year.

You must call the Technical Assistance Center (TAC) to request an exchange. TAC may request the dealer to perform additional work.

Division Telephone Number
US Light Duty Truck 1-887-4GM-TACS (1-877-446-8227)
US Medium Duty Truck 1-800-MEDIUM-D (1-800-699-4863)
Canada - English 1-800-263-7740
Canada - French 1-800-263-7960

If any internal components of a 2001 model year engine require replacement, the engine must be exchanged. Parts of a 2001 engine which may be serviced without exchange or removed for diagnosis are identified by an "X" in the table below.

Engine components on the Serviceable Components list above must be serviced according to the repair procedures in the applicable service information publication (manual). Engine components NOT included in the above list will require an engine exchange.

Important
Engine repairs or failures that are caused by components external to the engine will NOT fall under the exchange program. For example, engine oil cooler lines incorrectly installed causing an engine failure will have to go through GMSPO to obtain an engine assembly. The exchange program is created as a way to correct internal concerns and to take what is learned and find a way to eliminate these concerns. External components causing a failure do not provide any useful information in improving an engine. The engine received from GMSPO will be a new service engine.

Procedures
A thorough diagnosis must be performed on the condition in order to prevent unnecessary component replacements. Contact the Technical Assistance Center to verify that proper diagnosis has been performed. Upon review of the diagnosis, Technical Assistance will establish a case reference number and make arrangements for shipping an exchange unit to your dealership. To increase the effectiveness of the program, the Warranty Parts Center (WPC) will request the return of the unit removed only upon submission of a warranty reimbursement claim. Therefore the dealer is strongly encouraged to submit these claims as quickly as possible in order to facilitate the WPC request. DO NOT SHIP AN ENGINE TO THE WPC WITHOUT AN OFFICIAL WPC REQUEST.

Important
Failure to return the concerned engine will result in the dealership being debited in the amount of an entire engine assembly (dealer net).

The removed unit must be returned complete in the original exchange shipping container. For effective engineering analysis, please do not remove any components. Dress items on the removed unit must remain the same as the replacement engine (e.g., exhaust manifolds, throttle body, etc.). Dealerships returning engines/components having been even partially disassembled will be judged as violating this procedure and, as such, will be billed for all materials furnished.

Notice
The exchange unit will be shipped with a quantity of oil; check oil level before starting engine. Low oil level could result in internal engine damage.

Included with the exchange unit will be return shipping instructions, including a return shipping label (freight collect at destination) and partially completed Bill of Lading.

WPC/CPR Request
A request for return of engine component will be received at the dealership when the appropriate warranty reimbursement claim is paid. (Credit memos and WPC requests are received every Tuesday and Friday.)

Shipping Preparation
Remove the engine assembly/component as outlined in the applicable Service Manual. Drain all fluids from the removed engine.
Retorque any fasteners that were loosened or removed to the original torque specification.
Remove any plastic shipping plugs and covers from the exchange unit and install them on the removed unit.
If the concerned engine leaks, mark the area directly on the engine with a permanent marker.
Write the TAS case reference number on the repair order form.
Write the TAS case reference number on the component in a visible location.
Place the removed engine into the original shipping container. Attach completed return shipping tag to engine.
Shipping Instructions
Place a copy of the repair order, the completed return checklist and product feedback forms into the plastic press on envelope.
Remove the original shipping label and attach the plastic press on envelope with the return shipping label on it to the container. The Bill of Lading and Custom Papers (for Cross-Border Shipments) provided with the exchange engine are the only other documents required to be inserted into the clear envelope to return the removed engine.
Write the WPC request number and the TAS case reference number on the outside of the container with a permanent marker. To simplify the Exchange Program's core return process, the WPC will be coordinating all activities for core returns. See Se

Hey Obyone, thanks for the info on the TSB's. Is there actually one for the rear-end clunk/shutter and drivetrain noice when the back-end drops down at a stop? What about the clanking when shifting from drive to neutral, neutral to reverse? Any help would be appreciated.

The dealership may not have a legal responsibilty to inform you of TSB's,but this knowledge is a good opportunity for you to evaluate several dealerships and find the best one within a reasonable driving distance!

Just thought I'd inform all that the BBB really works. I've got 32K on my truck and have had this problem for a while. Chev had their "Final" attempt Tuesday, 3/20. Today I received a call from the BBB and Chev. We conferenced and Chev offered me a new motor. I took it. I'll have 30 days after the new motor is installed to evaluate and decide whether or not I want to proceed further with arbitration.

ABOUT THE 6/100 $0 DEDUCTIBLE WARRANTY
How do I get that with the BBB. I wish I would have pursued that one also.

GREAT INFO
This chat room has been awesome. I gathered critical data and shared it with my dealer on other issues with my truck and they are fixing them. Some of these problems I didn't know I had but realized that I did by reading about them. Great stuff!
