Torque Converter Clutch Inductive Signature Malfunction
2016-2016 Ford Explorer 3.5L V6 EcoBoost
The 2016 Ford Explorer is equipped with a 3.5L V6 turbocharged gasoline engine. Below you'll find detailed p1740 diagnostic code information including labor time estimates, cost ranges, and technician notes specific to this engine configuration.
Description
The TCC solenoid did not move when the PCM commanded it. This is an information code — there should be a more specific code stored in the Transmission Control Module. The TCC solenoid circuit performance is not as expected.
Symptoms
- Check Engine Light
- TCC not engaging
- Reduced fuel economy on highway
- Transmission overheating at highway speeds
Common Causes
- Faulty TCC solenoid
- Wiring issue to TCC solenoid
- Low transmission fluid
- Internal transmission blockage
- Contaminated transmission fluid
Diagnostic Steps
- Check for additional transmission DTCs in TCM
- Test TCC solenoid resistance
- Inspect TCC solenoid wiring
- Check transmission fluid level and condition
Repair Notes
Check for companion DTCs. Replace TCC solenoid if faulty. Service transmission fluid.
