Transmission Choices

[size-o]

Looking down the road, I seriously want some ass-whoppin performance and great mileage on the Hwy. Engine choice will likely be a stock LS3 (525HP) or a stroked version (600HP+), not sure yet. I've been reading up on TCI's new 6X 6 spd auto. Program it to give me all the performance using the first 4 gears and Hwy mileage with the last two gears.

Anyone out there install one of these. The 6X uses the 4L80E case so its big and I think I have some surgery to perform with the trans tunnel, just not sure how much. Some insight to this would help if anyone has some photos.

Thanks,
Perry

It fits tight but fits. Cross member and drive shaft mods.

Whoops, I guess I should add my signature. I have a 68 Chevelle Malibu. Car was originally a 327/4 spd. I found a frame from a big block car and now going with an LS-525 and TCI's new 6X (I think) unless there are better options. I will not be tracking the car, purely crusining and having fun.
