Oversized Secondary Pulley/Pressure Regulator Valve Kit
Fits RE0F11A, JF015E, CVT7
Tools Required
Symptoms:
- Push belt slippage
- Pulley breakage
- RPM surge
- Chatter on acceleration
Cause:
Excessive bore/valve wear allows circuit cross-leakage that exhausts critical oil pressure and volume. Wear at the inboard valve spool may cause high line pressure. Wear at the other spools will typically lead to low line pressure.
Correction:
Restore proper hydraulic control by refurbishing the bore and installing the Sonnax oversized secondary pulley/pressure regulator valve kit.
Oversized Solenoid Regulator Valve Kit
Fits RE0F11A, JF015E, CVT7
Tools Required
Symptoms:
- Chatter on acceleration
- Noise on acceleration
- Push belt slippage
- Increased push belt & pulley wear
- Low line rise
- Low solenoid feed pressure
- No ratio change
Cause:
Regulated solenoid pressure is directed to all control solenoids except the TCC solenoid. Depending on the magnitude and location of bore wear, regulated solenoid feed oil pressure could be either low or high.
Correction:
Re-establish solenoid feed oil pressure regulation by reconditioning the bore and installing the Sonnax oversized solenoid regulator valve kit.
