Symptom
Erratic harsh shift engagements.
Failed on or not connected, TCC
will not engage at less than one-
third throttle opening.
Increase in EPC pressure.
Rerun On-Board Diagnostics.
Warm vehicle to normal operating
temperature and rerun On-Board
Diagnostics.
May flash TCIL.
Improper gear selection depending
on failure mode and transmission
range selector position. Refer to
shift solenoid operation chart.
Improper gear selection depending
on failure mode and transmission
range selector position. Refer to
shift solenoid operation chart.
May flash TCIL.
Transmission slippage, erratic or no
TCC operation. May flash TCIL.
Early or delayed shift schedule.
Harsh shift, may flash TCIL.
TCC slippage/erratic or no torque
converter clutch operation. Flash
TCIL.
Open circuit causes maximum EPC
pressure, harsh engagements and
shifts. May flash TCIL.
Shorted circuit causes minimum
EPC pressure, limits engine torque
with partial fuel shut off and heavy
misfire. Flashing TCIL.
