TR60SN 09D Lockup Clutch Control Valve
Aisin AW TR-60SN and VW/Audi 09D transmission complaints associated with bore wear at the TCC lockup control valve include harsh 2-3 and harsh coast downshifts. This is due to the converter clutch remaining applied. When bore wear delays TCC apply, the vehicle RPM may surge or set gear ratio codes due to high slip rates. Installing Sonnax lockup clutch control valve kit 25741-29K will restore correct lube pressure and valve control timing.
- Salvages previously nonrepairable worn valve bodies and avoids expensive valve body replacement
- Highly wear-resistant sleeves provide additional support to the lockup and plunger valves
- Hardcoat anodized aluminum valves combat premature wear
- New spring maintains OE operating pressures and TCC timing
Symptoms
- TCC codes
- TCC apply & release concerns
- RPM surge on coast
- Harsh downshifts
- Overheated fluid
Cause
Bore wear at the TCC control valve and/or sleeve results in the converter remaining applied and transferring the shift shock. Loss of control also results in RPM fluctuation.
Correction
Sonnax lockup clutch control valve kit corrects lost lube pressure and unsynchronized control timing caused by worn components in the lockup clutch control valve train and/or bore.
