E-Shift Valve Spring

Part No. 37000-02

Listed Allison units commonly exhibit 3rd gear starts and trouble codes related to a sticking E-shift valve. The low return rate of the OE spring combined with flashing or wear ridges forming in bore over time allow the valve to hang up, resulting in these concerns. Crack down on sticking valve action by reconditioning the bore and installing stronger Sonnax E-shift valve spring 37000-02.

Symptoms:

  • 3rd Gear starts
  • Code P0872
  • Pressure switch stuck on
Cause:
Wear ridges or flashing in bore coupled with low OE return spring rate allows E-shift valve to stick.
Correction:
Prevent valve sticking and restore normal operation by reconditioning the bore and installing Sonnax E-shift valve spring.
  • Bore sizing tool 37000-02BST improves bore finish and removes flashing and ridges for smoother valve operation
  • Stronger spring helps prevent valve binding
