NEW master rebuild kit for the ST300 Transmissions found in the Buick, Pontiac & Oldsmobile transmissions
This kit contains all Borg-Warner clutches and "Steel plates." Make sure you get a kit with steel plates. The cheaper ones don't have them and you "will" need them. Also included is a Transtec soft parts kit with every rubber seal and gasket that you'll need to complete your rebuild. The kit comes with a new filter, adjustable vacuum modulator, and popular bushings. This kit also comes with a band which most kits don't include, but should always be changed.
Remember to soak all of your clutches in tranny fluid for thirty minutes before you install them.
