From what I read TCC should apply above 72 degrees, I have had it warmer and still will not apply. I have not seen the tcmode change from OFF either.
Ive been trying to find out if TCCES &TCCEP Failed means anything or not.
Appreciate the help.
Maybe, on my own vehicles (both gas), lockup doesnt occur until much warmer than that (I want to say~120F or so, but been a while since I logged it). Can take quite a while in the winter to get the trans up to temp.
I'll keep thinking of other things...
