Swapping from manual to auto tranny....

[stallion85]

My Father in law told me when you go from a manual to an auto tranny there is a bushing or reducer ring that must be removed to allow the bigger transmission shaft to enter the back of the engine.

He said the trick to get it out is to pump the area full of grease and use 6" of a 2" dowel and smack it on the end with a hammer and the force will cause it to pop out.

Does anyone have any experince with this or a picture. I have never changed trannies and or even seen the back of an engine outside of the vehicle

I'm don't think that is correct, once you switch to an auto there is no shaft going into the flywheel, for that matter there is no flywheel, you need to go to a flexplate.... unless I'm missing something I don't understand what he is talking about

 

[stallion85]

I think he was talkin about where the torque converter goes into? I really don't know and probably sound really stupid

 

[resurrected_jimmy]

the torque converter has no shaft to speak of, it is held on to the flexplate with three boltsthere is a small button on the face of the torque converter that lines up with the center of the flexplate but I have never heard of hammering any reducer out for this to fit

Are you talking about hammering this reducer/bushing out of your old flywheel or out of a flexplate for an auto tranny?

 

[stallion85]

Maybe that is what he met. I could have swore he said on the back of the engine....I will have to ask him again.

the center of the crank is not touched when hooking up an auto. it uses a flex plate with a torque converter bolted to it with 3 bolts. auto to manual yes but not manual to auto. you're free and clear to get to motoring

I think he's talking about the throwout bushing for a manual.

 

[55Willy]

the throwout bearing would be to be touched when doing a swap. also the method he discribed with the grease and a handle is the "hydro" method of removing a pilot bearing from a crank.

 

[bigbadchev84]

he must be confused with a ford, i installed a 400m out of a manual truck into an auto truck and the button on the convertor was jammed against the old throwout bearing, i have swapped out many chevy motors before and this has never been an issue......by the way the grease and dowel thing is a real mother f***er a pilot bearing removal tool is the only way to go

If its the pilot bushing ya'll are talkin about....its for the standard tranny. just leave it there. not worth removing if you are swapping to an auto. It wont hurt a thing.
