Symptoms:

  • Flare shifts
  • Neutral shifts
  • Harsh upshifts
  • Harsh downshifts
  • Gear ratio codes
  • Solenoid performance codes
  • Delayed Forward
  • Delayed Reverse
  • Wrong gear starts
  • TCC slip

Cause:

Excess solenoid pressure regulator valve to bore clearance may cause shift and pressure problems. All the linear solenoids are fed by this regulator valve. Shift quality depends on the amount of wear and often changes with operating temperature.

Correction:

The oversized solenoid pressure regulator valve will control the minimum and maximum pressure source for the solenoid.

You need this if...

Vacuum testing at the port(s) indicated fails to hold the recommended minimum in-Hg, or if wear is visually detected.
