Symptoms:

  • Low cooler flow
  • Overheating
  • Excess Reverse pressure & distorted housings
  • Bang shifts
  • Harsh upshifts
  • Bind-up
  • TCC cycling
  • TCC slip
  • Flare shifts

Cause:

Excessive solenoid pressure is caused by line pressure side-loading the steel solenoid modulator valve and the continuous oscillation of the valve, which wears the cast aluminum bore.

Correction:

The modified valve and high-grade aluminum sleeve allows the bore to be refurbished, and prevents side-loading of the valve and future wear.
