Description
104740-02K 6L80E Clutch Select Valve Spring Kit.
Mid 2010-earlier GM 6L80E–6L90E, applications have a tendency to set a P0751 (shift solenoid 1 malfunction) code. One of the causes of this is the OE spring force at the clutch select valves inhibiting movement of the valves, affecting proper control of clutch apply fluid.
Early-model production has updates made to reduce the spring force, however the updated springs are not available separately from OE, only as part of a new and expensive lower valve body.
Sonnax clutch select valve spring kit 104740-02K, updates these springs to the correct lower load to prevent the P0751, code.
-
No special tools required

Avoids expensive lower valve body replacement
