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

Oversized TC Switch Valve Part No. 35740-05 ZF

valve name: SV-WD Chrysler valve name: SV-TC Vehicles equipped with ZF8HP45, ZF8HP55 and ZF8HP70 transmissions may display concerns such as no lockup, excess TCC slip, soft or harsh apply and TCC codes.

In some cases, engine stall can occur due to TCC being stuck in the apply position.

These problems can be caused by bore wear at the TC switch valve, which allows crucial pressure loss from the circuit. Reconditioning the bore and installing Sonnax oversized TC switch valve 35740-05 brings the TCC switch circuit back under control by eliminating the path for fluid escape.

• Annular grooves help center valve in bore to reduce side-load wear

• Hardcoat anodized aluminum valve combats premature wear Need to use tool F-35740-TL5

TCC apply valve 8HP

OE valve name: WK-V

Vehicles equipped with ZF8HP45, ZF8HP55 and ZF8HP70 transmissions may experience converter shudder, TCC slip, overheating and/or damaged TCC linings, and may set various TCC-related trouble codes.

These problems can be caused by wear in the TC regulated apply bore, which allows critical control fluid to escape the circuit. Reconditioning the bore and installing Sonnax oversized converter clutch apply regulator valve kit 35740-13K prevents pressure loss and restores TCC operation by eliminating excess wear.

Required tool:

F-35740-TL13

Oversized TC Pressure Valve Kit Part No. 35740-18K

• Valve • End Plug • O-Rings (2) 1 Extra ZF valve name: WD-V Chrysler valve name: TC-V Vehicles equipped with ZF8HP45, ZF8HP55 and ZF8HP70 transmissions may have TCC problems such as harsh apply, excess slip, lining failure and related trouble codes.

These issues are often the result of bore wear at the TC pressure valve, which allows critical control pressure to escape the circuit.

Leakage here can also cause a 2-1 downshift clunk and diminished lube oil flow. Reconditioning the bore and installing Sonnax oversized TC pressure valve kit 35740-18K eliminates bore leakage for renewed TC and lube control.

• Annular grooves help center valve in bore to reduce side-load wear

• Hardcoat anodized aluminum valve combats premature wear Need to use tool F-35740-TL5

Oversized Clutch Holding Valve Kit Part No. 35740-20K

• Valve Spring

• End plug

• O-Rings (3) 1 Extra Fits five separate locations.

Clutch holding valve locations HV-C and HV-E use an end plug, the HV-A, HV-D and HV-B1 locations do not. The ZF8HP45/55/70 clutch holding valves provide solenoid feedback pressure to the clutch control valves, balancing each control valve to assist with apply and release of the respective clutch.

Excess wear at a clutch holding valve bore allows crucial fluid to escape the circuit. This can cause shift timing problems, a burnt clutch, ratio and solenoid codes, or loss of gears.

Reconditioning the bore and installing Sonnax oversized clutch holding valve kit 35740-20K eliminates bore wear and stops leakage for renewed clutch operation.

ZF8HP45, ZF8HP55, ZF8HP70 Oversized Priming Valve Kit

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.

Accumulator.pist.kit 6HP19, 6HP26, 8HP

Overly firm up/downshift feel or harsh engagement can be a sign of deformed accumulator piston bumpers in ZF6HP19/26/32 (Generation 1), ZF6HP21/28/34 (Generation 2), ZF8HP45/55/70, and Ford 6R60, 6R80 units.

The OE elastomeric (rubber) bumpers tend to take a set, resulting in loss of hydraulic damping. The Sonnax accumulator piston kit 95740-15K restores hydraulic damping with improved service life.

Features/Benefits:

Outperforms the OE by using Hybrid Technology, grooving and a proprietary blend of premium, high-energy friction material for high temperature durability.

Front Stator Support Bushing Part No. 35036

Package Quantity: 5

Symptoms:

• Bushing failure • Bushing wear • Harsh downshifts • Harsh TCC apply • TCC apply & release concerns

Cause:

OE bushing material composition allows premature wear.

Correction:

Install improved Sonnax front stator support bushing to restore critical clearances and resist untimely wear. OE front stator support bushings in ZF8HP45 units have a tendency to wear out prematurely due to sub-optimal material composition. This wear can lead to TCC apply and release concerns and harsh downshifts when TCC is engaged below 20 mph. Sonnax front stator support bushing 35036 restores worry-free operation.

• Upgraded material composition outperforms OE bushing

• Superior wear characteristics eliminate premature deterioration

WARNING:  Use of an arbor press is required for correct installation.

Do not use a hydraulic press or a bushing driver/hammer combination to install, as doing so will distort the bushing and cause fitment issues.
