“'Tween:” How to Identify the ZF6HP Series Valve Body that Bridges the 1st & 2nd Generation Designs
Maura Stafford
In ZF6HP19/26/32 (Gen. 1) and Ford 6R60, 6R80, 6R100 units, the variable force solenoids control clutch apply/release, torque converter clutch apply/release and line pressure. The solenoid pressure regulator valve ensures proper flow and pressure to the solenoids during hot conditions and low pressure. 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.
