E-Shift Valve Spring
Part No. 37000-02

Fits '00-'09 units only.

    Requires:
  • 37000-02BST (Recommended)
Allison 1000/2000/2400 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.
  • Bore sizing tool 37000-02BST improves bore finish and removes flashing and ridges for smoother valve operation
  • Stronger spring helps prevent valve binding
