When your TCM takes a bath...

[Chad Lares]

Thanks again guys for all the help in learning the technical part. I'll post another video of this replacement when the new TCM gets here.

A little footnote to computer's, microprocessor's, rom's & prom's when handling. Follow proper ESD procedures. Electro Static Discharge. The little static spark one doesn't see or feel and POOF... Time for more parts., now or later when they fail. Nice video.

Sparky the electron just Smokey Beared your electronics, CAMO

You will see a few of us call that “the little green smoke escaped” or “you let the green smoke out”. We’re describing a blown unit.

Always ground yourself when working on components with delicate electrics. Just tie a stripped wire to a radiator and tie the other end to your wrist.

Hello, did your transmission light turn on when you turned your ignition on? On your old tcm?
Thanks,
Cory

Yes, replaced the entire TCM. Everything works good now. Took it out for a drive and it shifted through the gears normally!

Can you share where you found one at a good price?

rockauto. $151 plus shipping. Also, it was $49 for a new EPROM.

Having trouble locating. Do you have the item description or part numbers.
Only showing options for turbo diesel?

Is it an6 of these?

I am pretty sure you are not going to find it for any civilian 6.5L application even the H1, the TCM they used in the HMMWV was for an early 90s GM truck with a 6.2L and a 4L80 transmission.
99% of all the 6.5L used the DS4 IP so those engines had an ECM and a different TCU

Did I miss the one for the turbo?

I could use it. I’m setting up a spare box and internal ‘puter.
