Corvette transmission swap

Unread post by CrazyW » Fri Jun 16, 2017 12:43 pm

I have a 1986 corvette with the 700r4 automatic. These are weak transmissions and I intend on building the motor so my question is how hard will it be to swap in a 4L80E auto overdrive, what it will require, and does anyone know the difference in the gear ratios of the 2 different transmissions? They are both 4 speed automatics...

besr bet for interchange is call a wrecking yard. Most yards have interchange books on what you can swap around.
