SES Light Question

[pahl]

I tested the stealer and went to another mechanic and have they have both came back with the same answer. They are saying the computer unit (sorry for not knowing the exact terms here) on the transmission or module most likely needs to be replaced as it is giving no signal to the main computer causing the SES light, or could be a lack of communication, either way most likely the module needs to be changed.

I am not sure what to search for to learn more about this module. The stealer wants over $1,300 for it. Is this something I could order and replace or have my mechanic replace or am I stuck with going back to the stealer?

Thanks,
Eric

Ok, I did my homework...
The correct term is called "Transmission emergency program (DDE control unit)"

Has anyone had to replace this module before?

Is this module available for purchase other than the stealer?

Is it a bear to have installed?

Any assistance will be much appreciated.

It the truck doing anything that would indicate the transmission is a problem? Thats not a common unit to fail. Try disconnecting the Battery for about 10 minutes then clear the code and see if it returns.

The Dealer says this the computer tests show the transmission is fine when the computer is hooked up directly to it. Its just the communication between the two computer units.

I havent tried disconnecting the battery, I'll give that a try and let you know.

Thanks,

if you know the Part no. its easy to ind how much it costs online without getting it from your dealer to avoid ripoff.

These control units rarely fail. First thing to check is the wiring harness and all connections. Failures with electronic components are usually at the connectors, Also, you can learn all about the TCM here:
