Welcome to the forum.

Sorry, I'm not following you. What is the problem that you need fixed? The trans won't shift into the next gear?

Sounds like maybe you are in limp mode from what he describes....

 

[pimpski25]

are the the 1,2,3,4 and D all circiled on the display? also is the CEL on? if so what codes are you pulling?

 

[Addict75]

yes whit manual mode but whit my original tcm we have 1,2,3,4,5 and D

Sounds like your going through what a lot of us already have, the TCM might not be the problem check out this thread.

Ok but whit the new TCM the dealer put it on fix they original problem but give a new trouble. So maybe I need to change the TCM and ESM ?

What was the original problem?

You don't know at this point what your issue is, you need to start narrowing down the possible causes. I would start by cleaning the ECM or if your under warranty have the dealer replace it.

i agree, you should definitely take apart and clean first... some guys on here have had great success with it. some think it's just a band aid fix. i had problems about 6 months ago, cleaned it and it has been fine... just use some contact cleaner. i will try to locate the link for the walk through diagram on how to take the shifter assembly apart. there's a couple tricks to getting it off

 

[Addict75]

do you know where is located (ECM)?

 

[Tcnj80]

Look at post #16 in the link I posted.

 

[Addict75]
