In Chrysler 845RE and ZF8HP45/55/70 units, the variable force solenoids control clutch apply/release, torque converter clutch apply/release and line pressure. The priming valve insures proper flow and pressure to the solenoids, and is especially crucial during hot conditions and low pressure. Low solenoid feed pressure at idle can create delayed engagement or wrong gear starts. This priming valve also limits the maximum pressure to all the solenoids. Excessive solenoid feed pressure can flood the solenoids causing gear ratio codes, harsh up/down shifts and excessive line pressure. Reconditioning the bore and installing Sonnax oversized priming valve kit 35740-21K eliminates bore wear and stops leakage for proper solenoid pressure control.

Hardcoat anodized valve combats premature wear
Annular grooves help center the valve in the bore to resist wear
