2013 Impala LTZ. Acting all sorts of crazy and I believe the TCM is bad or the wiring to it. I cannot seem to figure out the location. Does anyone know the location to the TCM?
I checked and didn't see it there. Are you sure? When I look up the part on autozone or wherever... it's this huge black thing. It doesn't look like the TCM I've seen in videos and stuff is why I'm confused.In the air box. The smaller of the two is the tcm, the larger is ecm. Well protected and gets air flow to keep them cool.
In this case, the 6T70, it to is inside the trans.TCM is an electric device. Brain.
Valve bodies are Hydraulic devices in trans.
Some TCM's are on the trans.
Some are remote.
