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
