Vehicles equipped with Aisin AW TR-60SN and and VW/Audi 09D transmissions may experience slippage in 4th, 5th or 6th Gear during steady driving. They also can experience slippage or shock on kickdown. These problems are caused by excess wear in the solenoid modulator valves, which results in improper solenoid pressures. Replacing the worn solenoid modulator valve or valves with Sonnax solenoid modulator valve kit 25741-18K will ensure the solenoids are fed the proper pressures, and will eliminate excess slippage and shock on kickdown.

• Hardcoat anodized aluminum valve combats premature wear and features annual grooves for better centering in the bore
• Sleeve is highly wear-resistant to increase life
• New end plug and spring for proper calibration
