#32 of 161 2 Seperate Tranny's in a Week!! by judadriver Jul 03, 2007 (6:51 am)
I own 2 2007 Suburbans my tranny went on the 1st. 35k . Dealer went in and fixed some things inside of it. No sooner than I get it out the dealer my other starts to slip 20k. This is the worst I have lost all confidence in these vehicles. This time the whole tranny will be replaced on the week of 4th of July!!!
#33 of 161 07 Silverado(NBS) w/similar problems by 07max Jul 05, 2007 (12:03 pm)
I have a 07 1500 Silverado (NBS; LTZ; 13,000 miles; 6.0L) w/similar problems to those listed here. Mine tranny seems to be slipping or very slow shifting (OD down to third) when driving up a steep slope (5% or greater) or on a very long slight incline (similar to trailer haunching) as well as noticeable loss in power on the bottom end with a very noticalbe power range increases during hard exceleration. I have now had it at the dealership 7 times. The dealership has updated the AFM as well as other unspecified computer updates but with no improvement at all. They are going to be adding a computer monitor from GM to the truck next week and will be sending the monitor to GM for evaluation but they are telling me this may be a 6 to 8 month process if it is found to be a program error since they will have to have EPA approval for any changes.   Has anyone else had a computer monitor installed that is sent to GM?   Has anyone talked to their dealers about lemon laws for their problems and if so what has been said Replies to this message: judadriver (Jul 05, 2007 2:23 pm)

07Max said: Has anyone talked to their dealers about lemon laws for their problems and if so what has been said ____________________________________________________________ The lemon laws are pretty much a state issue and each state has different interpretations on what constitutes a "lemon" regarding vehicles and different guidlines on what you need to do to certify that you have a "lemon". Check out your state laws and see what they say. Replies to this message: 07max (Jul 06, 2007 1:40 pm)

Replying to: rockman59 (Jul 06, 2007 9:25 am) Thanks for the input on the lemon laws. I have checked for my state (TN) and think I that may be able to proceed, but would rather have the truck fixed or replaced on good terms if possible. Will keep you informed on my progress.
#37 of 161 Re: Does the 2007 Chevy Tahoe Have A Transmission Problem? [glockfan] by c3gm Jul 11, 2007 (10:47 am)
Replying to: glockfan (Nov 26, 2006 7:32 am) We have a 2007 Chevrolet Avalance 1500 LTZ.   The Transmission, under acceleration from a stop-light, made a POP sound, then revved up to redline. The transmission only had Park, Reverse, and 1st gear. When revved up in first the transmission would whine. This vehicle had only been put into 4 wheel drive once to make sure it worked, when it was new. This vehicle's mileage is mostly highway, very few city miles. The vehicle has a total of 27,673 miles on it.   This problem resembles the same issue from the 1992-1996 model years where the Spline Drive (input shaft) pin, also reffered to as the SUNGEAR would snap. Under acceleration, approximately every 30,000 miles, the pin would snap causing the input shaft to slam into the forward gears of the transfer case. This could destroy the transmission, transmission housing, transfer-case and/or transfer case housing depending on how severe the load is under acceleration during the failure.   GM knows this part breaks easilyunder load or heavy acceleration (merging, passing, emergency acceleration) and has for nearly 20 years (1998). Why does it appear again in 2007?   C3

WAKE UP!!! People are wondering why their Chevy's have issues like the GM lemons of old. If you did research before buying your lemon GM vehicle, you would find out that massive changes haven't been made to the GM architecture in just about 10-15 years. Not to mention, the new Tahoe, Suburban, and Avalanche are being built cheaper than ever before. There's gotta be something behind how GM can now make almost 10 grand more on the new Tahoe than the old one, yet the new one has all of these "revolutionary" changes. The only change I see is just what GM does - replaces the body parts, stiffens the frame every now and then, and keeps the old 30+ year technology under the hood. Wake up - buy a Ford - you'll be much, much happier. Replies to this message: c3gm (Jul 24, 2007 2:40 pm) tahoe007 (Aug 04, 2007 10:31 am)

Replying to: thereisnospoon (Jul 23, 2007 11:08 pm) Update:   2007 Avalanche-   1) Replaced Sprag Gear 2) Replaced clutch packs 3) Re-flashed PROM for DVD Navigation system 4) Re-flahsed PROM for Console   This cured the problems of the DVD navigation system failing with the A/C Controls and Radio rendered inoperable.   So far, 1400 miles and the transmission is still holding together. No one has raced off of a redlight under full-throttle acceleration, nor have they attempted to repeatedly stand in the throttle in order to accelerate rapidly. My guess is, the next time it happens, it will break again.   In response to the Ford Comment. our 1999 Tahoe worked flawlessly for 167,000 miles- and I do mean FLAWLESSLY.  The difference was, that 1999 Tahoe had driveline slop which caused clunking and clattering and sounded as though something was wrong, when in fact, there was nothing wrong.   I don't hear of these problems in the Pickup, why is it only happening in the SUVs?   C3

Replying to: thereisnospoon (Jul 23, 2007 11:08 pm) YOU ARE SO RIGHT! I read these messages and the transmission problems are the same as the 1997 Tahoe. I was a diehard GM owner, never would buy anything else, until all the problems with my $34,000 1997 Tahoe which left me on the side of many roads. In 2002 purchased a Ford F-250, best truck I've ever had (and still have). I use the Tahoe for short trips to the store, but no long trips from home. I finally did wake up!
