4L60E=electronically shifted 700R4...with minor differences.

The 4L60E is not the best auto tranny by any means. stock LT1's and LS1's can burn them up. And it is had to find someone who can rebuild one and have it last more than 35K.

Century Automotive is the only place I have heard of that can build a 700R4 or a 4L60E that can stand up to any real power. Hell their famous in the F-body community for being able to do it.
