Symptoms:
  • Bang shifts
  • Bump shifts
  • Clutch failure
  • Flare shifts
  • Inconsistent shift quality
  • Shift codes
Cause:

Wear at the various end plugs allows critical circuit leakage of solenoid modulator, secondary regulator, and line pressures. These pressure losses impair control of the clutches, resulting in various shift complaints and eventual failure.

Correction:

Install the Sonnax O-ringed end plugs to prevent oil pressure loss at the plugs.
