Trying to read file for initial tune and I get "TCM Unsupported".
This is an '06 Trailblazer SS E40 PCM with an E43 TCM.
Here's a quick back story.
Truck blew motor, dealer replaced, said tune wasn't stock, also replaced PCM, did not replace TCM. Trucks fine. Fast forward to now...I do a set of modifications to truck, go to license truck by pulling stock files and get this error, how do I fix it or what do I look for.
I'm assuming this TCM was also modified but wasn't replaced when the dealer replaced the PCM and now I cant read it. I have a stock 2006 TCM file from another TBSS, can I flash just the TCM to get it back like it should be or??
I'm a little lost on this one, as this trucks out of commission until we come up with a solution.
Help me out here guys.
Thanks in advance.
