Swapping to AUTO or 5-speed? The auto trans uses the flex plate as mentioned and NO pilot bearing. A spacer goes between the flex plate and crankshaft and if the throwout bearing is left in the end of the crank the rotating assembly will bind and the engine wont turnover. The 5 speed trans bellhousing and auto bellhousing have identical bolt patterns for mounting...shouldnt have to change anything as far as that is concerned.

I learned how fun it is to swap engines from a manual trans rig to automatic last summer when powering the 85' Celica. Had to re-pull the engine after leaving the pilot bearing in the crank....ooops.
