Diagnostic Trouble Code (DTC) Information

Diagnostic trouble code (DTC) information

Condition
The solenoids are controlled by power stages in the transmission control module (TCM). The transmission control module (TCM) opens the power stages to activate the solenoids and sends a voltage through the circuit. Diagnostic trouble code (DTC) TCM-0061 is stored if the control module registers an internal fault in the power stage circuit for solenoid STH.

Substitute value
- Transmission control module (TCM) "Limp Home" program initiated.

Possible source
- Internal fault in the control module.

Fault symptom[s]
- General orange warning lamp lit.
- Malfunction indicator lamp (MIL) lit.
- No lock-up function.
- Harsh gear shifting.
- No shifting.

Hint: Harsh gear shifting can be caused by:
- no reduction of line pressure when shifting
- no reduction of line pressure when moving the gear selector between positions P-R, N-R and N-D
- no torque limiting request to engine control module (ECM) when shifting

No shifting - because the transmission control module (TCM) prevents activation of the solenoids. This stops gear-shifting.
