Diagnostic trouble code (DTC) information
Condition
Throttle solenoid SLT controls the line pressure in the transmission. The solenoid is controlled by a power stage in the transmission control module (TCM) output. The transmission control module (TCM) uses the power stage to control the current to the solenoid. A low amperage results in a high line pressure. A high amperage (approximately 1 A) results in a low line pressure. The amperage is primarily affected by the throttle position. Diagnostic trouble code (DTC) TCM-0118 is stored if the control module registers a short-circuit to ground in the solenoid SLT circuit. Solenoid SLT cannot then control the line pressure.
Substitute value
- The transmission control module (TCM) "Emergency mode I" program has been initiated.
Possible source
- Short-circuit to ground in the control signal cable or the signal cable.
- Defective solenoid SLT.
Fault symptom[s]
- General orange warning lamp lit.
- Malfunction indicator lamp (MIL) lit.
- No lock-up function.
- Harsh gear shifting.
Hint: The shifting may be harsh if there is no request for torque limiting to the engine control module (ECM) during shifting.

When to See a Mechanic
Stop DIY work and contact a certified mechanic immediately if any of the following apply:
- • You smell fuel, burning insulation, or see smoke.
- • Brakes feel soft, pull hard to one side, or make grinding noises.
- • 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.
