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.

Warning:

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.
