2011 Camaro, HCI
Started happening recently.
At WOT the car would drop into neutral sending RPMs to the moon. Thought nuked the tranny, but it drives fine.
Did some datalogs - when it happens, all the communications with TCM stop, speed jumps to 158mph, the rest of the data freezes.
Thought it was problem with the ground (G106 on the head) - replaced the O-terminal and the problem went away .... for half a day
Just did it again at WOT in 2nd gear.
Anyone had problem like that? I believe TCM is inside the transmission and there is just CAN bus, power and ground going to it, right?
Thanks in advance.
