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 will distort the bushing and cause fitment issues.
OE bushings in ZF6HP19 and ZF6HP21 units have a tendency to wear out prematurely due to sub-optimal material composition. This wear can lead to bushing failure, loss of correct pressure to the "E" clutch and "B" clutch, and gear ratio or solenoid codes. Sonnax improved bushing kit 95030-19K restores worry-free operation.
