2004 Volvo S80 L6-2.9L Turbo VIN 91 B6294TSECTION 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.

- • The engine overheats, stalls repeatedly, or misfires under load.
- • You are missing required tools, torque specs, or safe lifting equipment.
- • You are not confident in the next step or safety outcome.
