2012-2016 Tesla Model S 85 kWh Single Motor RWD
Description
The DCT hydraulic pump is not generating sufficient pressure for clutch actuation and gear selection.
Symptoms
- Check Engine Light
- Slow gear changes
- Clutch slip during shifts
- No drive in any gear
- Transmission warning light
- Creep function loss in stop-and-go
Common Causes
- Worn hydraulic pump
- Low hydraulic fluid level
- Internal seal leak
- Pressure accumulator failure
- Clogged hydraulic filter
Diagnostic Steps
- Check hydraulic fluid level
- Read system pressure PID
- Test pump motor operation
- Inspect accumulator charge pressure
- Check for external fluid leaks
Repair Notes
Replace hydraulic pump or repair internal leaks. Replace accumulator if pressure does not hold.
