TCM-0060

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-0060 is stored if the control module registers an internal fault in the power stage circuit for solenoids S1, S2, S3, S4 or S5.

Substitute value
- The transmission control module (TCM) Emergency mode Ill program has been 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.
