#37 of 413 Re: Does the 2007 Chevy Tahoe Have A Transmission Problem? [glockfan]
Jul 11, 2007 (11:47 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?

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.

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?

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!

All of you should visit the National Highway Traffic Safety site located at link title
You can file complaints and fill out forms that send your issues to the investigative group at NHTSA. Its the only way to get GM to recognize the issue.
Also, Contact CNN and file a request for STORY submission at CNN.COM

I noticed my first slippage early. Same response from the dealer as may others have posted here. At 41,500 miles, just finished turning a sharp curve on an incline when I got the loud bang (thought I'd blown a tire) and immediate loss of power. Remaining was reverse and limited lower gear. Chevrolet dealer said "not a common problem" but it may be time to get rid of this one. My fourth GM over the past 10 years, but not sure I'll stick with them. Car is still under repair so we'll see.

I had the same problem. 07 Z71 Suburban with 8,200 miles. This is crazy. My dealer, however (valley Stream Chevy) did tow the vehicle to its shop, and they REPLACED the entire tranny unit. I cant understand why a NEW 50K vehical could have tranny problems. I LOVE my truck, however I cannot deal with these kind of 80's quality problems.
