Product Description
KIT IS NOT COMPATIBLE WITH ZF6HP19 6HP28 6HP34 (GEN-1)
Tooling Required
ZF6HP21 6HP28 6HP34 Oversized Solenoid Pressure Regulator Valve Kit
ZF Valve Name: DR.REO-V
In ZF6HP21/28/34 (Generation 2) units, the variable force solenoids control clutch apply/release, torque converter clutch apply/release and line pressure. The solenoid pressure regulator valve insures proper flow volume and pressure to the solenoids during hot conditions and low pressure operation. Low feed pressure at idle can create delayed engagement or wrong gear starts. This valve also limits the maximum pressure to all the solenoids. Excessive solenoid feed pressure can flood the solenoids causing gear ratio codes, harsh up/downshifts and excessive line pressure. Sonnax oversized solenoid pressure regulator valve kit 95740-64K restores proper solenoid function.
• Kit fits either M-shift or E-shift valve bodies
• Hardcoat anodized aluminum valve combats premature wear
• Matching spring reproduces OE function with the oversized valve
Symptoms
- Delayed engagement
- Flare shifts
- Harsh downshifts
- Neutral shifts
- High line pressure
- Harsh upshifts
- Wrong gear starts
- Gear ratio & solenoid codes
- TCC slip
Cause
All solenoids are fed by the solenoid regulator valve. Worn valve/bore surfaces allow critical pressurized oil to cross-leak to the sump, reducing available oil pressure and volume for the solenoids. Shift quality will be adversely affected by wear and operating temperatures.
Correction
Sonnax oversized solenoid pressure regulator valve kit eliminates cross-leaks and loss of critical oil to the sump, restoring correct oil pressure and volume available to the solenoids.
