Symptoms:

  • Bushing wear
  • Bushing failure
  • Clutch failure
  • Harsh shifts
  • Gear ratio & solenoid codes

Cause:

Premature wear due to sub-optimal OE bushing material in ZF 8-speed units allows fluid loss and misalignment that results in harsh shifting and clutch failure.

Correction:

Install improved Sonnax P1 planet bushing to restore critical clearances and resist untimely wear.
