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


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.


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


Caution: Use of an arbor press is required for correct installation. Do not use a hydraulic press or a bushing driver/hammer combination to install, as doing so may distort the bushing and cause fitment issues.

OE bushings in Chrysler 845RE and listed ZF 8-speed units have a tendency to wear out prematurely due to sub-optimal material composition. This wear can lead to bushing failure, harsh shifts, burnt clutches and gear ratio or solenoid codes. Sonnax improved bushing kit 35030-01K restores worry-free operation.
