There's a sucker born every minute!
did you also know that the stock wires have developed twice the resistance as new in as little as 7,000 miles? the sucker is you, especially if you buy the stock wires over again. LOL
also, i'v upgraded my stereo system and found that the magnecors eliminated the final tidbit of interference, not to mention that the slight cackling i was hearing is totally eliminated.
might want to think about what you're spewing off about before you spew.

I have the Firestone P265x75R16 with 5000 miles , and they are really noisy . Did you get a trade in for the old ones . You got a good price at $300.

Info - PCM Reprogramming #99-06-04-053
Powertrain Control Module (PCM) Reprogramming (Do Not Reprogram Using The Same Download Files As Those Already Present In The Control Module)
1990-2000 Passenger Cars and Trucks with Reprogramable PCM
It is strongly recommended to NOT reinstall the same software and/or calibration download file(s) into the powertrain control module as those that are already present in the PCM. There is no technical reason that the download files inside the PCM would ever become corrupted after the control module had previously been successfully programmed. A P0601 (Control Module Read Only Memory) Diagnostic Trouble Code would set in memory and the MIL would be illuminated if the controller memory became corrupted.
The Techline Information System 2000 (TIS 2000) PC, combined with vehicle information gained through the Tech 2, can determine when an attempt to reprogram a PCM using the same download files (as those already in the control module) is being requested. If this is attempted, the TIS 2000 PC currently displays the following message:
NOTICE
THE CALIBRATION SELECTED IS THE CURRENT CALIBRATION IN THE CONTROL MODULE. PROGRAMMING WITH THE SAME DOWNLOAD FILES IS NOT AN EFFECTIVE REPAIR. SELECT ( YES ) TO CONTINUE PROGRAMMING THE CONTROL MODULE, OR ( NO ) TO CANCEL.
Effective in the first quarter of 2000, the TIS 2000 PC will indicate:
Important
THE CALIBRATION SELECTED IS ALREADY THE CURRENT CALIBRATION IN THE CONTROL MODULE. REPROGRAMMING WITH THE SAME DOWNLOAD FILE IS NOT ALLOWED.
Certain learned values, such as: (but not limited to)
fuel trim (previously known as block learn memory),
IAC learned position in various park/neutral and air conditioning on/off combinations,
certain OBDII diagnostic thresholds,
automatic transmission shift adapts
will revert back to their unlearned starting point values after a reprogramming event occurs.
It is feasible that the engine or transmission might temporarily operate differently after a reprogramming event, until these values are re-learned. Relearning occurs while operating the vehicle through normal driving routines. If the same download files are simply reinstalled, any changes noticed in engine operation will likely disappear in a short amount of time and/or driving distance.
Reprogramming the control module with the same download files that already exist in the module will only accomplish a warranty claim for a non-effective repair, and a likely comeback.

Enter your VIN. It should show you a listing of available programming update and current programming for your truck. If there are new one's available for driveline growl or transmission updates, you can print and show it to the service manager. I would think there would be. Maybe jed1894 could shed more light on the subject as I believe that he had a V6 also. I would definitely check the site out.
I saw your post #99, and are yours molded or flat rubber? If they are rubber, where did you get them and will they fit on a 2K Silver ado Z71 with wheel flares?
Thanks, Roger

I originally ordered OEM flat,white bowtie mudflaps from the dealer and am still trying to track them down if I can. I like the standard look and the flexibility of the flat flap.
1) front end vibration - apparently corrected on the '01 production run by adding extra bracing around the front end
2) steering shaft - any '01's experiencing this one?
3) wind noise - whether caused by lack of weatherstripping around extended cab doors, poor fit of extended cab doors OR thin, poor fitting glass in extended cab doors, have any/all of these problems been corrected on the production line yet?
-- No vibrations.
-- No steering shaft problems
-- No window wind noise
-- No rear door closing problem in cold weather
-- No other problems I can find, and I'm *VERY* picky!
Love the truck, and especially those heated leather buckets, when the temp is -15F like it was this morning!

The only thing I did notice....... it seems that the 01 models are smaller (inside interior). I'm probably wrong but they sure felt smaller than my 00 2wd and 99 4x4. ??????

Info - Driveline Clunk #99-04-20-002
Driveline Clunk
2000 and Prior Chevrolet and GMC Light Duty Truck Models
This bulletin is being revised to update the models section and add information to the Important statement. Please discard Corporate Bulletin Number 56-44-01A (Section 4 - Drive Axle and Section 7 - Transmission).
Important
The condition described in this bulletin should not be confused with Driveline Stop Clunk, described in Corporate Bulletin Number 964101R (Chevrolet 92-265-7A, GMC Truck 91-4A-77, Oldsmobile 47-71-20A, GM of Canada 93-4A-100) or Bump/Clunk Upon Acceleration, described in Corporate Bulletin Number 99-04-21-004.
Some owners of light duty trucks equipped with automatic transmissions may comment that the vehicle exhibits a clunk noise when shifting between Park and Drive, Park and Reverse, or Drive and Reverse. Similarly, owners of vehicles equipped with automatic or manual transmissions may comment that the vehicle exhibits a clunk noise while driving when the accelerator is quickly depressed and then released.
Whenever there are two or more gears interacting with one another, there must be a certain amount of clearance between those gears in order for the gears to operate properly. This clearance or freeplay (also known as lash) can translate into a clunk noise whenever the gear is loaded and unloaded quickly, or whenever the direction of rotation is reversed. The more gears you have in a system, the more freeplay the total system will have.
The clunk noise that owners sometimes hear may be the result of a buildup of freeplay (lash) between the components in the driveline.
For example, the potential for a driveline clunk would be greater in a 4-wheel drive or all-wheel drive vehicle than a 2-wheel drive vehicle. This is because in addition to the freeplay from the rear axle gears, the universal joints, and the transmission (common to both vehicles), the 4-wheel drive transfer case gears (and their associated clearances) add additional freeplay to the driveline.
In service, dealers are discouraged from attempting to repair driveline clunk conditions for the following reasons:
Comments of driveline clunk are almost never the result of one individual component with excessive lash, but rather the result of the added affect of freeplay (or lash) present in all of the driveline components. Because all of the components in the driveline have a certain amount of lash by design, changing driveline components may not result in a satisfactory lash reduction.
While some owners may find the clunk noise objectionable, this will not adversely affect durability or performance.

I test drove a Ford and it doesn't have any clunk or clank when going from I to I, zero!
That much slop in the drive train = sloppy workmanship and it affect durability. GM is too lazy to fix the problem and they are hoping their clanky trucks will last until the warranty runs out.
"While some owners may find the clunk noise objectionable, this will not adversely affect durability or performance."
ROTFLMFAO!!
GM ya gotta luv em for all the BS...cause this was my first clunking vehicle, ever!!

ordered on 10/13/2000. Have read all the post on
problems with 2000 models.
Only have 250 miles on it yet but have found no
vibrations, wind noise etc. Owners manual now
says to wait until oil change light comes on
before changing. It should come on between 3000-10,000. Think I will go with Mobil 1 when it happens.
Have a A.R.E top ordered and trying to find a
running board I like. Will order the mud flaps.
Thanks for all the info you all have provided.
My first Chewy truck and I am impressed and hope to be able to say that a few miles down the road.
And don't forget "go bama".
P. also ordered some polish and stuff from Zaino.
Be sure to clay before using the Zaino.
Tried to get Chevy to do a buy back or at least help me get into another that won't subject me to pain, but the only thing they offered was extended warranty, so I will have to continue to suffer until they can come up with a fix, [which isn't likely] or I win the lottery which again isn't likely, as my state doesn't even have a lottery. I have been loyal to Chevy since my 69 camaro which was my lst car. Still have 69 rsss convert. & 92 camaro 25th anniversary convt, but thinking of doing a heav ho and buy something that works and not from GM.
My truck has been in 14 times, maybe l5 or 16 [hard to keep track unless I pull my paper work]
If there is a new update within the past month please let me know. Dealer has been great at trying everything and anything, its the big tech people and corporate that are ??? Thanks.....
The dealer checked with GM's Tech. Assistance and were told that the heater was performing to spec., I called that Customer Assistance line and was told that GM has a "Poor Heating Performance Review" currently looking into the problem (so I guess others have complained too.)
Is anyone else have complaints with the amount of heated air directed at the passenger's feet?
