Part Number: TAT-37000-02-SX

A sticking E-shift valve in an Allison series unit can be caused by a weak spring, an out-of- round valve bore, or excessive flashing on the valve body casting. The Sonnax E-shift valve spring has a higher spring rate than the OEM while the bore sizing tool allows you to improve bore roundness and remove excessive flashing.

Features & Benefits

Stronger spring with higher spring rate helps prevent valve from sticking.
Bore sizing tool improves roundness of the bore and removes any flashing for smoother valve operation.

Note: Use of the bore sizing tool is not required but is recommended.
