View Instructions Find a DistributorDelayed Forward engagement, burned Forward clutch, and/or Forward clutch psi low by 10-15 psi in vehicles with listed Ford transmissions are common complaints. These are often caused by a worn valve body at the manual valve bore, allowing excessive oil leakage. Replace the worn OE manual valve with Sonnax manual valve 96201-05 to prevent oil leakage and increase stability at the linkage.
- Hardcoat anodized aluminum valve combats premature wear
- The three spool diameters have been lengthened to provide increased stability and prevent oil leakage
- Exhaust flats added to the extended spools provide proper oil circuit control
- Lengthened spools and tightly toleranced cross-hole provide increased valve stability at the linkage
- Drop-in Zip Valve™ installs quickly and easily
