I don't know if anyone on here will be able to answer this but will a 700R4 out of a 89 Trans Am fit into a 86 Corvette.
Thanks Jimmy.

Re: 700R4

Tail shaft/housing is different, vette has a torque arm back to the IRS center. It bolts to tranny and rear end. The rest should be the same.

Re: 700R4

The output shaft is .950" shorter. You will have to grind that amount off.
