When we built version 1.0 of the car it had a 700R4. Version 2.0 is getting 4L60e built by Atomic Transmission in Villa Park, IL. What I have learned is that the mounting position on the tailshaft is further back and the top of the case is a little fatter. Which means there is a a whole lot less room on the sides for you to reach up and install the wiring and tighten the coolant line fittings.
For now the empty 700r4 case is going back in as I can't seem to find one. You can see I had to drill new holes in the G-Force Crossmember for the 4L60e which are currently hidden under the tape.
