I am sure this will be my first and last time i buy a GM product. These issues have left a sour taste in my my mouth. 2 transmission issues within the first 4000 miles and 4 months. This silverado will be traded in as soon as i can and going with my original choice of a Tundra.

Have you checked with your local BBB office? Lemon law vary by state. However, the one common denominator is the three repair rule. The manufacturer has three attempts to fix the problem, if it is not repairable for whatever reason, the BBB can be instrumental in getting you a buyback which is way better than trying to trade or sell a truck with known issues.
 
Just saying....

galvezfj,
I understand your frustrations. Due to your situation and concerns as well as the department you have worked with, there isn't a lot that I can do. They are better quipped to handle your situation. I apologize for your inconvenience.

#1276 of 1486 1996 gmc sierra - no overdrive/drop down by earlybird6754

#1277 of 1486 1996 gmc sierra - no overdrive/drop down by earlybird6754

1996 gmc sierra 1500 350ci automatic. Shifts through all gears great with no hesitation, noise, vibration, etc. Problem: if you floor it for rapid acceleration to pass or whatever, you can hear the tbi open up and fuel dumps in, but it actually SLOWS down....it will not "drop down" into overdrive. However, once you let off of accelerator and fuel stops dumping in, it runs fine. Again, in automatic or manually, all gears shift, act, sound, feel, etc. normal; it just won't kick down into lower gear. Whether you're in 2nd, 3rd, or 4th gear, it will not shift down automatically.
All fluid levels and conditions are good. Vehicle did sit up for nearly 2 years and only driven 50 miles, maybe. Did perform a transmission flush, drain and refill fluid. I'm thinking pressure solenoid, valve body vacuum, or trans control module. Any ideas, suggestion, etc. will be GREATLY appreciated. Working with limited financial resources, so I can't afford changing out parts which aren't bad. Need all the help possible. Thanks.

I too am having transmission problems but was told it has to do with the torque management system on the vehicle. Also, I was told that no repairs could be made to fix it and that I should consider it to be normal. I bet if it was their money on the line they'd want an investigation done. It's a potentially serious mechanical problem as well as a safety issue.

#1279 of 1486 6 speed GMC transmission problems by alcianfarini

Keep trying, I complained so much, sent a certified letter to the ceo of GMC, finally the district manager called and offered to buy me out of my 2011 and into a 2012. I am still waiting for the dealer to locate an identical truck but hope to get results soon. The truck is dangerous, it actually accelerates as I'm slowing down and it is always in the wrong gear constantly up and down shifting and bogging because it won't accelerate when necessary! Keep screaming or we will need a class action law suit!

#1280 of 1486 7th time to the dealer? by super6sierra

Jul 19, 2012 (8:49 am)

I have posted on this before. My truck is at the shop again. I am pushing them to look into the TPS this time. I continue to have downshift/re-acceleration issues with my 2009 GMC Sierra 5.3l 6-speed 3.42 rear end. Very, very, very frustrated. I have an open case number and talk with GM reps...they are very professional, but absolutely no help. The dealer is great...the problem is GM engineers...they need to come up with a fix for this known problem and known issue. I pay a ton of money for this truck and it is the nicest vehicle I have ever owned (bought in '10 with 12K on it). I now have 69K on it.
there are no codes...which renders the local dealer mostly helpless as they try to fix the crappy programming of the TPS, TMS, and Transmission. The loaner vehicle I have this time is a 2012 Colorado with the 5.3l in it and a 4speed. Oh, how I miss the 4 speed. This little truck rocks...seems so much "less confused" than my Sierra.
I drove a 3.5l EcoBoost the other day...WOW. Ford has that thing dialed. Makes it pretty hard to want to stay in this GM product. Don't get me wrong...I really, really like my truck. Like how it looks, interior, power, fuel economy...but when I have been driving a vehicle for 30K+ miles and continue to bring it in to the dealer to fix a very, very serious drive ability issue and they are left stranded by GM who, with all their R&D and techy know how can't seem to program the thing to run correctly...well, quite frankly, it sucks rocks.
Should be getting a call today from the dealer. Will let you know if whatever they "fix" this time changes anything.

Thank you for your reply! I actually figured this would just get lost in cyberspace. I will email with info. I also still have the same problems only progressively getting worse. I am planning yet another trip to Dominion Chevrolet Richmond, Va. very soon to look at these problems. 13,000 miles and I want documentation before my warrent expires or runs out.

Definitely sounding like a solenoid issue. If you've never replaced that on your stock transmission, I'd suggest getting on line to GM Parts Giant, GM Parts Direct... one of those should have your solenoid.
 
The R&R will be tough if you don't have a trusted transmission person that will do the service without telling you "you need to check this". A tale-tell sign is if the transmission fluid is it's pretty ruby-red, and there's no sediment, get the solenoid changed. The R&R shouldn't be more than $100 if you have the part. Call the stealership and get the part number, and roll from there. If the fluid is in good shape you should be able to re-use it.
 
Let me know how you make out.
