Description

 

Fits mid '10–earlier. Compatible with all models except early, 1st design 6L80 plate 24246916.

 

Mid 2010-earlier GM 6L45/50/80/90 transmissions 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

 

  • Additionally, updates were made to the OE separator plate to further improve clutch feed pressure, clutch backfill exhaust pressure and compensator feed pressure. 
  • If the unit's separator plate is NOT the updated version, Sonnax recommends replacing the plate with the updated version when using this spring kit.
  • See instructions for details.

 

  • Springs (2)

 

Symptoms:

  • Code P0751
  • 1-2-3-4 Clutch burned
  • 3-5-Reverse clutch burned
  • Cruise control disabled

 

Cause:

These symptoms can be caused by faulty OE clutch select valve springs, setting the valve apply pressure too high.
 

Correction:

Sonnax springs reduce the apply pressure needed to move the clutch select valves, reducing the tendency of the P0751 code to set.
