manual 2.8 to auto trans?

[91dime]

I have a 91 manual 2.8 s10, and im selling the engine. The man who wants to purchase it has a auto 2.8 s10. What will need to be changed to put a 2.8 set up for a manual to a auto trans? Is it just the flywheel needs to be swaped for a flexplate, and maybe a different ecm?

Thanks for any help.

Nothing he will just have to put your engine in his truck and use all his current stuff to install it. There is no difference between the engine

If it is only the engine getting swapped in nothing is needed except to change the flywheel. ecm is the same because manual and auto trans have the same gear ratios/settings only thing different really is the clutch+pressure plate between engine and trans and the stick shift and clutch pedal in the car other than that it is easy to use an engine from manual to auto or auto to manual.

One thing to check before trying to bolt it to the trans is the pilot bushing may have to be removed. I'm not sure but it may be in the way.

I didnt really think there would be a big difference. I never thought about the pilot bushing, anyone had this problem before? Thanks alot for the help.

anytime when you are installing an auto make sure the pilot bushing/bearing is removed. ive seen were the bushing hangs out a slight bit and it pushes back on the snout of the converter and warps the flex plate, and can cause it to break.

This is semi related so I figure I would ask it here.

I have an 82 2.8L out of a Chevy S10 Blazer that originally had a clutch and flywheel installed and I want to bolt a TH-200 on the thing.

I have a flexplate and torque converter out of a 2.8L FWD 1982 Chevy Citation and I want to use these.

The bolt hole pattern is the same on the flexplate as on the flywheel so it will bolt up, but the diameter is about 1/4 inch or so less than that of the flywheel.

I am wondering whether or not the difference is made up by a different size gear on the starter or if I need a larger diameter flexplate. I have a feeling that getting a flexplate to match my starter will probably be cheaper than buying a new starter.

I'm also wondering if the torque converter I have will work for my application. I have yet to see if the splines match up, etc, but even so I suppose it still may or may not be a match for my engine/trans combo.

Anyone have any thoughts on this?

Thanks,

Daniel

you need a rwd flexplate. the fwd stuff uses a smaller diameter flexplate than the rwd because of the smaller bellhousings on fwd transmissions. you should be able to use a rwd flexplate from a small bellhousing 700r4.

is the torque converter the one that was with the tranny??? if it is, what was motor and car did it come from???

Don't forget the radiator. You need the coolant lines.
