BUSH KIT SONNAX(8HP45/50/55/70/75/845RE)

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.

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:
The Sonnax parts restore hydraulic integrity and provide a positive seal with the pump bore. The Sonnax boost valve kit restores hydraulic integrity and provides a positive seal with the pump bore.


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. The Sonnax improved bushing kit restores worry-free operation.

  • Upgraded material composition outperforms OE bushings
  • Superior wear characteristics eliminate premature deterioration
