Cause:
The K1 clutch control valve provides source pressure for control of clutch apply and release. Responding to TCU and the linear solenoid, the K1 control valve will establish control timing of apply and release relative to engine torque. Bore wear can cause either an overlap, bind-up or premature exhausting of clutch pressure, resulting in a flare shift.
Correction:
The Sonnax wear-resistant sleeve and valve correct circuit pressure loss and restore control timing of the K1 clutch control valve.
In Aisin AW TR-60SN and VW/Audi 09D units, bore wear at the K1 clutch control results in delayed engagement into Drive, flare on 4-5 upshift and harsh 5-4 coast downshift. This bore wear will cause a clutch overlap condition (bind-up) or premature exhaust of clutch pressure (flare). Installing Sonnax K1 clutch control valve kit will correct source pressure and clutch control timing.
