A new two (2) piece number five (#5) thrust bearing assembly (7D234 bearing and 7D235 race) (Fig 1 )
A forward clutch sun gear (7A399) (Fig 2 )
A reverse sun gear (7A019) (Fig 3 )

SERVICE TIP

To install, refer to the latest version Workshop Manual for disassembly and reassembly of the transmission.

CAUTION: ALL COMPONENTS IN THE KIT MUST BE INSTALLED OR THE REPAIR MAY NOT BE EFFECTIVE AND MAY CAUSE AN INTERNAL NOISE OR LOSS OF FORWARD AND/OR REVERSE.
