The direct clutch is applied in reverse, 4th and 5th gear by the variable force PC-C solenoid. Fluid pressure from the solenoid is routed through the reverse modulator and reverse engagement valves, which then stroke appropriately to route apply pressure to the direct clutch. Wear at the reverse pressure modulator valve bore and end plug results in the leakage of the solenoid feed and direct clutch apply pressures, resulting in slipping or loss of 4th/5th gear, burned direct clutch and delayed reverse engagement. The Sonnax reverse modulator valve kit 56947J-53K can restore proper hydraulic function and prevent future leakage.

  • Critical valve spools incorporate annular grooves for better hydraulic centering and reduced wear
  • Critical valve spool length increased by almost 20% for increased sealing and stability
  • End plug incorporates O-ring to positively seal critical PC-C solenoid feed oil
