Flywheel vs flex plate - Saabnet.com Bulletin Board
There's no bushing/bearing on the automatic. If you swap the motors, you just need to swap the flywheel from your old motor to the new one - the automatics use a flex plate instead of a flywheel, which looks similar in that it has a big ring gear around the outside of it for the starter to engage, but it is much lighter, as the (heavy) torque converter is bolted to it and performs the same function as the weight of the flywheel on a manual car. If you take it apart, it will be obvious what you need to do. There's no need for a bushing since the torque converter and flex plate are bolted together and don't need to rotate relative to each other.
