CVT Line Pressure Control Performance
2000-2012 Mitsubishi Eclipse 2.4L I4 🇩🇪
Description
The CVT line pressure is not within the expected range for the current operating conditions. Line pressure controls clamping force on the belt/chain.
Symptoms
- Check Engine Light
- CVT belt slip
- Shudder during acceleration
- Delayed engagement
- Unusual transmission noise
- Overheating transmission
Common Causes
- Faulty line pressure solenoid
- Worn oil pump
- Clogged CVT fluid filter
- Low fluid level
- Internal seal leak
Diagnostic Steps
- Check CVT fluid level and condition
- Monitor line pressure PID on scan tool
- Test pressure control solenoid
- Inspect CVT fluid filter
- Check for internal leaks with pressure test
Repair Notes
Replace line pressure solenoid. If oil pump is weak, transmission rebuild may be required.
