Default 84 auto tranny?

I have an 84 vette that I'm putting a 6.0 lq4 in.I pulled The motor the other day to find that the tranny case is busted up only to bolts holding it in.What I would like to know is there any difference in the 700r4 case.The tranny out of the car shifts fine so can I just get a 700r4 case and switch everything over.I know the c4 corvette trans are shorter but if I use the guts and tail section that should not be a prob correct. thanks for all and any info.

As long as the case is from an 84-86 you are correct.

They are date coded, so that should help.
Externally, they look the same so the date stamp is key.
There are 255 changes in the 700r4 from 84-93. That is why I said many.

I appreciate all the info you have given me Pete K now I can find a case and get back to sticking this motor in.It suck when you find things like this but it's all part of hot rodding.Just hope I don't see the guy who had the vette before me again.I had already bought a tci constant pressure valve body and finned aluminum pan for the trans or I would prob do something else anyway thanks again.
