After driving 20 minutes or so TCC locks and stays locked in all gears
except 1st.It will unlock if i touch the brake pedal.
After logging i also found PWM current goes to 0 shortly before TCC locks
Two DTC's-trans component slipping and TCC stuck on.
Looking at trans input and output shaft rpm I see no major slippage
relative to gear ratio.
Anyone have a clue?
If the TCC solenoid was stuck on it would not release when brake pedal was pushed no?
PWM solenoid shot?
Trans seems to shift fine otherwise.can any of the v6 guys control TCC clutch with vcm controls in scanner? mine are greyed out. ???
Edit: Codes are maximum adapt long shift and TCC stuck on.
