AOD doesn't have a pilot bearing, does it have a bushing?

About to bolt up the AOD to the Blueprint. It's still got the throw out bearing in it. What takes it's place for this AOD? I'm having a heck of a time finding good info this am. 🙄

Thanks!

Automatics don’t use a pilot bearings
Your torque convertor bolts to the flywheel so that centers everything up.
If yours has a pilot bearing, pretty sure you need to remove it. Try the bread trick, it works slick.

If I am wrong someone will chime in.

The snout of the torque converter fits in the back of the crankshaft. No bushings, no bearings. If there is a pilot bearing in the crankshaft it will need to be removed.

Sounds like this is a new engine (?) If so, nothing needs to be done. No extra parts needed.

A pilot bearing is needed in a manual transmission because the input shaft of the transmission will spin at a different speed from the crankshaft when the clutch is not engaged. The pilot bearing allows the different speeds and supports the front of the input shaft keeping it aligned.
The snout fits in the end of the crankshaft to keep it aligned and supported as well. Since the convertor doesn't spin at a different speed from the crankshaft, no bearing needed. Just a loose slip fit so the convertor can move in and out a tiny bit as the convertor is installed and the flexplate flexes.

What they said...you did get the correct flexplate for it right?

thick grease works with a socket as well, no food supply needed.
