However, my issue is because some are upset (as I would be too) is the half-truths or sometimes outright lies that get put on this forum.
I guess it's their way of getting "revenge".
I will continue to do the "half truth alerts".
Here is what happens.
When I pull away from a stop, it shifts very, very quickly (under normal driving, when I hammer on it, this doesn't happen) down into 2nd and third gear...it goes to 2nd before I even make it through the light. So, when I want to then bring it up to speed, it is already locked down into usually 3rd and wants to stay there unless I go past probably 3/4 throttle, at which point it jumps down violently to what feels like 1st. Seems like it is tuned very, very aggressively for mileage. Very, very annoying as it does that all the time..so neighborhood/slow speed city driving really stinks. Tranny is very confused. If I put it into tow/haul, it stays in gear much longer and there is no issue. Seems like it might be tuned for an engine with much more torque or a 3.73 or 4.10 rear end.
2nd. When slightly rolling (1mph or less) and then trying to accelerate, there is a slight 1/2 second delay, then the power kicks in and everyone's head jerks back. I have to be very, very, very gently on the pedal and feather it through this until the engine/power engages. This seems like it might be a throttle issue or something to do with the fuel delivery. Does this truck have a throttle cable, or is it electronic?
3rd. Problem. Towing. Under hard acceleration (not w.o.t., but well past 3/4 throttle) and towing 2k--4K trailer, there are multiple times where the tranny "jumps" or slips in between 2nd-3, 3-4, and 4-5. Engine revs slightly and it jerks into gear. Again...seems confused.
I have had this truck to the dealer for warranty work on tranny. There are no codes. They could find nothing. I explained everything to my dealer as I have in this post. It is due to go in again. I checked tsb's and couldn't find any that seemed to be related to the issues I am having. HELP
2 times ago at my dealership they gave me a 2012 as a loaner. Totally different truck even though it had the same engine and the same tranny and the same rearend (3.42). Clearly the 2009 needs an updated tune , but GM refuses to both acknowledge this and act on it. Help. Somebody. Please.
The first gear in the 6 speed is a VERY SHORT gear. It will shift from 1st very quickly. That's what it is supposed to do.
"3rd. Problem. Towing. Under hard acceleration (not w.o.t., but well past 3/4 throttle) and towing 2k--4K trailer, there are multiple times where the tranny "jumps" or slips in between 2nd-3, 3-4, and 4-5. Engine revs slightly and it jerks into gear. Again...seems confused."
Use "tow-haul mode". It will hold on to gears longer. Under hard accelerating, more often than not it will downshift more than one gear.
"Seems like it is tuned very, very aggressively for mileage."
Yes, it is.
It seems a longer test drive would have been in order for you. You shouldn't have bought the truck.
Except for the "JERK" you are describing, the truck is acting exactly as it is designed.
"You shouldn't have bought the truck". No, GM should fix their junk, period. If the same transmission acts right in a 2012 vs 2009, 10 etc, then there obviously is a software/hardware/hardparts issue. Deal with it.
Sarah, if you are reading this, I've been back by the dealer twice, and supposedly the GM rep is due by the dealer next week. There has been no decision on the howling differential and vibrations so far. My patience is wearing thin, and if it comes to it, I will tear into it myself. If I do, it will be made public via website or youtube or wherever. i know ive been there at least 10 times so far. Ridiculous.
Frankly, I just wish your Honda would have been 1 year model earlier as the prior 2 years to yours are known for transmission failures around 100K. Shouldn't be, but do fail just like clockwork. I don't know if the software update that Honda is doing on the 2005-10 accords, approx. 1.5 million cars recalled, fixed that '05 '06 problem. I believe the recall was for a lot of the same complaints found on this forum.
Your right. Except I have the 4 cylinder motor. The 6 cyl. motors was the one that had the tranny failures.
The still had issues until the last couple of years in the mini vans and Pilots.
And I don't even want to bring up the part about the 'road force' tests that didn't do squat other than scratch and dent up two of my wheels. Thanks for that fine piece of work, gm certified tech.
If he damaged your wheels doing a road force balance I would talk with the service manager.
I am an Avionics Tech for the Air Force and as far as #6 on your list I think your right with the stray volts going to the adjustable peddle. The guy who wired your truck was probably having a bad day.
Thanks
Many happy miles,
Sarah

SO, put the truck on jack stands, turned off the traction control, and viola....still got the shakes, whines, and backlash clunk. (With the front tires stationary....which was supposedly the culprit all along).
Drove a '12 chevy with the identical driveline and it didn't have that mysterious pedal movement. Apparently that is the anti-lock brakes re-booting/system check.
Long story short, not a damn thing fixed. Supposed to meet with GM rep this week. They're gonna replace it or they can supply me with a permanent loaner.
(P.S.-- if there is a forum monitor on here, please remove Chuck1's posts...no help and clearly has zero benefit on this forum except to just tick people off with real problems...thank you)
Thank you for your updates on your situation. Please feel free to email me directly.

its worse now then before.
a tech at the dealer told me to avoid any stop and go traffic and it will shift fine.
REALLY?
a very disappointed customer.
I'll keep it in mind, but I'd like to know what you can offer that hasn't already been covered on my end. You can contact me directly ..... jon@stockhub.com .
GM's corporate governance has really poisoned the well with me. Of all the new gm cars/trucks that I have bought, this vehicle has more problems than all those combined.
I refuse to take a bath on this thing after waiting patiently for months. I suppose the thing that pissed me off the most is the 'policy' from GM technical assistance NOT to supply the dealer with hard parts until the vehicle has reached a certain amount of mileage. I was told 5,000 miles was the 'break-in' period. In other words, GM's policy is not to fix squat until a customer has endured 5,000 miles of problems. The supposed way to override said policy is to get a GM rep involved. I did....which I shouldn't have to bend over backwards, and say 'mommy please' to a GM rep to get the nod to fix my vehicle. The powers that be best clean house on that policy since it is a 'precondition' to warranty that is not stated in the limited warranty that accompanies the vehicle. I would direct them to the language in the Magnason-Moss Act, 15 USC 2301, the Texas DTPA, etc. And you wonder why you are losing market share, jeez.
How many vehicles do you think you could sell if the warranty said "3 years or 31,000 miles, because you have to drive it 5,000 miles to get certain things fixed, so we are really not offering 'bumper to bumper' coverage for a certain amount of time beginning at the moment you drive it off the lot" .
To put it bluntly, if GM wants to 'dig in' and knock heads on this, so be it. The truck is one thing, the deceptive warranty is another. They've had 5 months to resolve it and I'm not going to wait another 5 months. We'll be in court neck deep in discovery to flesh out these 'policies' by that time. Good luck with that.
This doesn't help anyone either. It also doesn't help Edmunds who promotes vehicles of all types and makes.
I think the real issue is not anyone other than you and GM telling half truths and lies to cover up mediocrity of new Gm trucks.
Lets be totally honest here. The issues that are being brought up are known issues with the NNBS trucks. No secret to anyone who follows GM trucks.
Customers are using these forums to try and convince GM to do as they did in the OLd Gm way and take care of them and their vehicles.
Having owned Gm for 40 plus years I am so disappointed in GM that I am at the point of buying from a competitor.
The solution to all the rhetoric and forum posts would be for GM to very simply take care of warrant able issues as they arise and the customers would have nothing to complain about.
So GM, let's get 'er done.
I'm sorry to hear that your transmission has given you so much difficulty on your truck, and it sounds like you're in the middle of some current transmission troubles? Have you already worked with Customer Assistance in regards to these issues?
Best,
Sarah

They wanted me to return my truck and swap it out for another one and I didn't want to. I explained to them I just wanted it fixed.
As long as it keeps running I'm happy! ;-)
Maybe when the warranty runs out Chevy will have a new truck rolling out for me to go and buy? :-)
Let me know, though, if I can ever answer any questions or help in any way. I'll be happy to do what I can!

Well i had my truck back for a little over a month now and it stated acting up again. This time the transmission is dis-engaging when shifting between 3rd and 4th gears. feels like the clutch is still engage and im in neutral for about 5 seconds before 4th gear kicks in. I can even rev the engine during these 5 sec with no foward movement. Im starting to regret my decision to buy a silverado and should have stuck to toyota which i have 3 vehicles from. This is becoming more of a headache after spending 42k on a truck that doesn't work properly. truck is more a little over 3 1/2 months with 4k miles on it.
Thanks for the update, even though it isn't a happy one. If we can get a Service Request set up for you on this, please send the following information our way at socialmedia@gm.com: your name and Edmunds username, phone and address, the last 8 digits of your VIN and current mileage, and the name of your involved dealership. A brief description of the situation would also be helpful as my coworker Christina answers inbound emails and this will help her understand the context.
Regards,

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.
Thank you for taking the time to email me with your concerns. I see that you have a previous case (71-1065018870). I apologize for your frustrations and inconvenience. There isn't much I can do. If you need further assistance I would recommend contacting 866-790-5600 extension 11040.

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.
Just saying....
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.

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.

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.
I have called GM and setup a case on it and they are playing the normal games of nothing wrong with it. Like you said if it was there dollar I bet it would be fixxed or taken back.
