Primary Governor Valve

Part No. 12802-01

Fits ‘90-‘03 units only.

Complaint:

  • 2nd Gear starts
  • Early upshifts
  • Late upshifts

Cause:

The primary governor valve wears or sticks, creating erratic governor oil pressure.


Correction:

The Sonnax wear-resistant governor valve has longer lands and more support area.

The OE aluminum governor valves in Chrysler RWD units become worn because the soft-coat anodizing wears off. The valve is not being optimally supported in the bore because the OE valve land is narrow. Sonnax primary governor valve 12802-01 has been improved over the OE version in both material and configuration for greater durability and performance.

  • Sonnax valve is made from hard-coat anodized aluminum for better wear resistance than the OE valve
  • Includes longer valve land for better support to reduce bore wear and maintain shifting consistency
  • Valve can also be installed into new governor bodies to prevent future wear from occurring
  • Use of this valve will not change shift timing/governor pressure from OE calibration
