Chevy Silverado/GMC Sierra's w 8100/Allison

BAD NEWS FOR US WITH 8100 UNITS on order!!!!!!
***(or maybe its better they fix it before we get it)***

Several post have indicated January Production Dates for units with the 8100/Allison. Please keep us informed if that have happens.

Today received information direct from Pontiac Assembly Plant that no 8100's are building thru at least end of Feb. because Engine is BACK on CONSTRAINT (No info as to why yet). Nothing said about the Allison so assume Duri/Allisons ok--

OUCH!!!

    Why my order was pulled yesterday. I have a 2500HD CC with the 6.0 ordered. Are they all built at the same plant and is that the only plant that builds them? I noticed on whhels .com that the 8.1's were hard to get.
  • n75v111n75v111 Posts: 243
    -- I don't think the 6.0 has any production hold.

    Pontiac is the only plant anywhere geared to product the 2500 HD's in all its versions/cc's, xc's etc.

    Still waiting to hear back from the Planner Guy but the 8.1 according to him last November were ready to ramp up to 30% -- so something has happened. The person at Pont said can't 'build the trucks if they can't build the engines' what ever that was supposed to mean??

    Sf0383 6.0's should be coming thru i would have thought,

    but I have not seen any recent 8100 post -(since the first Sept. built dealer units were built And those ALL had a component problem that was rectified before each unit shiped-Those engines ALL went thru SPECIAL test before GM allowed each one to ship)-indicating customer orderd units actually being delivered. Anyone seeing recent deliveries for dealer inventory??

    Hope all of you with 8100's and those that eventually will have will post here your performance, milage etc.

    So far all post have indicated the 8100/Alli will be a V10 killer in pulling gas milage and performance etc.-- Everything we all want to know with this new Super 8100/Alli's combination as time goes on--

    Thanks

    is the 2nd week of February or so I've been told. I would guess that means a build date of this week or next?

    Recieved my LT 2500HD crew cab 4X4 8100/allison on Dec 05. Ordered on Aug 02. Pictures at www.picturetrail.com/mth Mileage is around 10 to 10.5 mpg.
  • Ordered a GMC HD, CC, 6.0, short box, auto, SLT, the first week of August. Was advised by dealer in November due to a shortage of 6.0 engines I could not get a truck. Changed the oder to an 8.1/Allison. In December was advised no leather was available so I changed to an SLE. Order was accepted in December with a TPW of 1/1/01. Checked with dealer today and was advised it was shipped yesterday but can't seem to find it on the BNSF tracking site. I'm not sure if we can believe any of the information that is being offered. The only thing we know for sure is that the CC's are hard to come by.

    Locally they are receiving 2500 He's with short beds and 6.0. Also received a STANDARD CAB 2500 ID with Diesel/Allison. Drove it, and was NOT impressed. Made as much noise as any other diesel, and the transmission shifted like a bus! Which I guess shouldn't surprise me! NO delivery date locally here on 8.1's....
  • n75v111n75v111 Posts: 243
    Thanks for all this information. Keep it coming.
    Central IA also seeing HD xc SB with 6.0 but no new delivery 8.1s.

    Dealer said late today that Pontiac assembly 50% of 8.1 production units going into one ton CC's so maybe still some hope that 2500's xc & cc will get some share of available 8.1's.

    Hope these post keep showing delivery in Jan. into Feb. Keeping fingers crossed.

    Have 'ado LT xc 4x4 SB on order Sept. 05.
    --mth1 Dec. 05 date might be some hope before march. With these long deliverys don't forget to push for $1000 loyalty certificate---

    - Tim
  • mgdvhmanmgdvhman Posts: 4,162
    dry?

    what rear axle ratio...?

    - Tim
  • sf0383sf0383 Posts: 204
    Nice looking ride you got there. I'm curious about wheels and tires too. I talked to a tire dealer yesterday about trading mine. He was saying 285's would fit but I'm not sure I believe him. I'm thinking more like 265 and maybe 275 because I don't want to have to trim anything to keep from rubbing.
  • sf0383sf0383 Posts: 204
    Keep us posted as to the delivery. What do you need to track the delivery and where do you get it? I have the order number will that do me any good. Where is it being delivered to? I am being told to expect 10 days from plant to middle Ga.
  • n75v111n75v111 Posts: 243
    If delivery will be by rail on Burlington, they have a web page using last digits of VIN #.

    Delivery by truck transport don't know.

    I just priced one at the dealer and the 8.1 is now $850 MSRP on top of the 6.0

    Let us know about the size on the tires/wheels
  • Hello All,
    Salesman just called me with the good news that my truck was built this week at Pontiac and was shipped yesterday. I live on the east coast so it will be 10 - 12 days before they get it to the dealership.The dealer will take a day to put in a sliding rear window, bedliner, Trac-Rac, and my free toolbox. If all goes as planned I should have it by the end of the month. The salesman gave me the VIN #, is there a site to track the shipping progress? It will be coming by rail.
    I still want to put a set of 285s on as soon as the truck arrives.From what I understand it will require trimming the air dam (belt sander?), raising the body by adjusting the torsion bars 4 complete turns,and reprogramming the computer with a Hypertech ($300.00). Where can I get the Hypertech unit? Any other information will be appreciated. If I can figure out how to do it I'll post a picture when I get the truck.
    BTW this vehicle was ordered on Oct 20th.
    Countin' 'em down, Scott

    Outstanding pictures of your truck. Several questions for you....

    1) Looks like the color you have is Victory Red, correct?

    2) I recognize the wheels as Weld Racing Outbacks, what width wheel did you go with?

    3) What size tire do you go with?

    4) Who did you buy from at Huffines? We do business with the Huffines family of dealerships and I am in the market for a 2500HD.

    Many thanks!

    Zach

    1. It is not Victory Red it is Sunset Orange
    2. The wheels are Weld Outbacks. They are 16x8 with 4.625 inch backspacing. Problem -- Due to the fact they are not hub centric The wheels gave my truck a slight vibiration. I have removed the Welds and put the Goodyear tires on the factory wheels. I have not found a 8 on 6.5 bolt pattern wheel that is hub centric. The center bore of the wheel will need to be 4.75. I am still looking.
    3. The tires are Goodyear ATS 285/75/16
    4. I have purchased many trucks from Ted Goldberg and he always does what he can for me. Good guy to deal with.
    I will try to take some more pics with the factory wheels and 285 tires
  • mgdvhmanmgdvhman Posts: 4,162
    I like the sunset orange and have seen it look many colors in different lights....

    fooled me

  • Congrats on the new vehicle. I've posted several times whinning about the wait for delivery of my 8.1/Allison. I ordered in early August. My dealer advised me my truck was shipped on January 16th, and delivery should take 14 to 21 days to Montana. I have a VIN but can't find the truck at either the BNSF or UP tracing sites. (If you want the site addresses let me know.) I ordered white with 3.73 gears with no locking differential. I am hoping to improve on the 9.0 MPG test results the major magazines have posted. I avoided the locking differential because I feel they have a tendency to fishtail on icy roads and we have tough winters in Montana. I also ordered new white wheel flares from my dealer to replace the black. I'm hoping the truck is a midyear year model with white so I can save the $290 cost. What's the deal with the toolbox? I haven't heard anything about any free stuff with the truck.
  • On your 1/17/01 post you suggested pushing for a $1,000 gmc loyalty certificate from GM because of the long waits. I have never heard of a loyalty cetrificate and have bought five new GMC trucks. Have I missed something along the way?
  • n75v111n75v111 Posts: 243
    Go back here and review trw3's post 864. Further discussion on topic New/Sierra etc post starting at 270-342 etc.

    I think you have to push the distric rep hard ball style and 'build your own case' but GM does give them out. waiting to see also!!

    I have taken the Welds off and put the factory wheels with the 285's on. Just thought people would like to see how it looks. http://www.picturetrail.com/gallery/view?username=mth I kind of like the factory wheels. Let me know what yall think.
  • n75v111n75v111 Posts: 243
    what the upper right area is on the radio - looks like some sort of display but not sure.

    Also thought LT CC's were to have Climate Control - Did I miss that or could you zero in on those two areas to show more detail??

    Thanks

    also drove an 8.1 allison. It was on display along with the Duramax and 6.0. I only drove the 8.1 and thought it had some power. The trans was VERY NOISEY. A lot of whines and other high pitched sounds. My son said it sounded like a Supercharger! The 8.1 had 4.10 gears and I was hoping for some funny car type burn outs. It did chirp the tires but really didn't light 'em up. I thought the trans shifted as smooth as other autos, I was expecting harsh shifts.
    The truck I drove had the lowest level interior, vinyl seats, no carpet. A higher level trim may have made the trans noise less intrusive.
    Hard to compare to my Super Duty because mine is a 4WD 5speed V10. I am interested in driving like compared trucks for a true evaluation.
  • mgdvhmanmgdvhman Posts: 4,162
    I like the poilished 2500 wheels also...but thought 285's were a little of a sqeeze for those wheels?

    CC's do have climate control as an option....at least on LS/LT..

    Allison Noises are normal...at least until warmed up.....Salesman even said they recieved a video about just that..and that it's a truck tranny and it's gonna make squeals and whines....I said they should put the video in every glove box..

  • mgdvhmanmgdvhman Posts: 4,162
    Damn Todd....what did ya do?..change the wheels in teh lot and take pics the same day and not even move the truck?

    LOL

    I can see the climate control no problem.......

    I thought the stock wheels would make 285's wear too funny....like too much of a curve on the tread?

    285/75/16's?

    - Tim
  • mgdvhmanmgdvhman Posts: 4,162
    I see from a post they are 285/75/16's....any trimming or lifting to make them work?
