Fitment Notes:
The complete kit is listed for GM TH180 and TH180C applications, excluding Holden. Other transmission names above describe individual component applications only and do not expand complete-kit compatibility.

Confirm part number K54900-RS, the installed transmission identification, and required sealing components before ordering. The gasket and rubber kit carries a 1969-on designation; verify the complete kit against your specific transmission.

Friction plates, steel plates, a filter, bushings, and transmission fluid are not listed among the supplied contents. Inspect the transmission to determine whether additional rebuild parts are needed.

For the refill stage, consider Lubegard ATF only after verifying the selected fluid against the transmission’s required specification. Fluid is purchased separately.
