Oversized Pressure Regulator Valve Kit Part No. 35740-01K

• Valve

• Sleeve

Vehicles equipped with ZF8HP45, ZF8HP55 and ZF8HP70 transmissions often develop erratic or high line pressure due to excessive wear in the OE pressure regulator valve bore and/or sleeve.

This wear allows critical oil loss, preventing proper line pressure regulation. Without correct balance oil pressure, the PR valve will be out of its desired position, resulting in line pressure instability and possibly restricting cooler and lube flow.

A deteriorated bore can cause lowered line pressure, resulting in soft shifting and burnt clutches. Reconditioning the bore and installing Sonnax oversized pressure regulator valve kit 35740-01K renews pressure regulator action for revived line pressure control in all ranges.

• Hardcoat anodized aluminum valve combats premature wear

• Annular grooves help center valve in bore to reduce side-load wear Needs tool F-35740-TL

Part No. 35740-21K

• Valve Spring

• End plug

• O-Rings (3) 1 Extra ZF valve name: DR-RED-V (DR-V) Chrysler valve name: PR-V 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.
