Any suggestions?
Its an electrical switch mounted on the drivers side of your tranny. In earlier Allison trannys it was poorly shielded from the elements and prone to failure. I'd start there.
If you have one let me know price, your location and if you accept paypal or how you would like paid. I live in Maryland(20832) my email is shawnmili@yahoo.com
I unhooked the egr valve elect. when it begain to act up to see if it would change the running of the truck, it didnt. after the truck sat turned off for a min i re started it and it ran fine. but the trans temp stayed up around 200.
Anyone have any isdea or help?
I parked my truck for 2 weeks and come back home. When i started it up and put the trans in overdrive it don't want to shift right. It takes it awhile to shift from first to second and takes awhile to pickup speed. When u let off the gas it shifts fine, but if u get on it, with the pedal mashed down it wont shift right. ANY HELP WOULD BE APPRECIATED.
Thanks
Thanks,

This is the info I saw on EBay:
2000-2007 Chevy Silverado 1500 Transmission Cooler
Genuine GM Part Number: 12497071
Recommended for trailer towing upgrade w/ 4.3L (LU3, L35), 4.8L (LRV), 5.3L (L59) and 5.7L (LM7) engines. Helps prevent transmission overheating.
One day it was very sluggish in drive and when I got to destination there was no reverse. Started up 3 hours later and no problem
Two months later started it up no gears would engage. Went away for a long weekend started up went in gear, no problem.
Before the gears problems, my dash gear indicator went out and I had to count gears to get into drive.
Bought the truck used 3 years ago and the Trans temp gauge had never worked.
Once the TCM was replace no gear problems, gear shift indicator came back and now the Trans temp gauge works.
The first shop thought it was the main computer, hard time getting a read. Referred me to another shop and inside 20 min they found the problem with the TCM.
Happy with fix, very expensive though.
:confuse:
The transmission has failed because the casting of the transmission housing prevents proper lubrication to the 3rd and 4th gears. Depending on how the truck is used may depend on when they finally crap out.
I called GM and they said that I needed to take it to a GM dealership to have it diagnosised before they could do anything. Well they told me it was catastrophic failure and they could fix it for 2200.00 but can't guarantee that it won't happen again.
If they replace it with a new tranny for 3300.00 they can warrant that it won't happen. DAH !!!!!! must be a problem with that tranny like both shops said. I have found numerous people on the net with the same issue.
I have been a devout Chevy man for 33 years and my trucks aren't used for plowing or towing. I see that some people have had this tranny replaced 2,3,4 and 5 times??????????
Also, when braking to a complete stop, it almost feels as if the truck is in tow mode. Tranny seems to downshift slowly and i have to apply brakes harder due to it trying to continue to go. Now the brakes are squeaking.
So needless to say, I have bought a $33,000 truck that didn't come with a much needed neck brace or a supply of brake pads. Very disappointed.

What the heck could be making the noise?
I know she hasn't met me so I must sound stupid on the phone. If I do that GM still can't guarantee that they will pay for anything at all. I told her that they don't need me to do that since I've already had two transmissions shops and their dealership tell me the same thing by just driving it.
They want 2200.00 to rebuild without a guarantee that it won't happen again so why would I want to pay them another 400.00 of my hard earned bucks? I just laughed and said " you are kidding me right". She then told me that she had to talk to another District Manager and call me Friday.
She did call while I was on my bike going home from work and when I got home and called she was gone for the weekend of course. Tomorrow will be two weeks without the truck and I need to do something soon. I will call her this morning and if I get the same answer I will pull my truck from the dealership after paying 76.00 for a diagnosis that took 2 minutes.
I am probably going to buy a used tranny locally and then trade it in because these trannys seem to like timebombs that can blow at any time. I have been set against buying anything other than GM but it may be time to break out of that mold.

I told them no thanks, that isn't much of a deal for a lifetime Chevy owner. Then they called the next day and offered to give me a certificate for 500-1000 dollars off of a new truck. WOW!!! I could get that much off on my own. Have you noticed that they do respond to problems on this site with trucks that are 2008 and newer?
Well I have been without the truck for two weeks now so I had to do something so I purchased a completely rebuilt tranny. I was told that it has all of the GM problems taken care of by replacing them with upgraded parts that should have been put in it to begin with.
The cost is 1000.00 plus 259.00 shipping both ways to return my original one. I don't know yet what I will do once it's repaired. I may trade it on a new Toyota although I have a problem with driving non GM products.
I have a number of friends and coworkers that own them and seem to be very happy with the trucks performance and reliability.
Truck has 38k miles- I'll be heading off to a dealer with my info.
Thanks for your support

We are trying to research the problem and we are working with the transmission company. They are testing it every 100 or so miles to see what is happening. I read one post that said it could be in the computer system.
Can't trust any car company any more.

Please keep me informed on how the repairs go. Thank you,
