Symptoms:

2-3 Shift concerns
4-5 Concerns
Delayed Reverse
K3 Clutch burned

Cause:

The K3 clutch control valve provides source pressure for control of clutch apply and release. Responding to TCU and the linear solenoid, the K3 control valve will establish control timing of apply and release relative to engine torque. Bore wear can cause either an overlap and bind-up or premature exhausting of clutch pressure, resulting in a flare shift.

Correction:

Sonnax K3 clutch control valve kit corrects circuit pressure loss and restores control timing of the K3 clutch.

Flare upshifts or downshift bind-ups in vehicles with the Aisin AW TR-60SN and VW/Audi 09D transmissions can be caused by a worn K3 clutch control valve. Wear at this valve causes incorrect shift timing, which can also cause clutch distress. Sonnax K3 clutch control valve kit 25741-08K helps restore shift timing.
