700R4 differs from a 4L60 E in what way?

    I'm putting a later model chevy motor in my friends rig. He was thinking about getting the 4L60E that originally came behind the motor (5.3L I think). Anyway, can any of you think of any reasons why it might be better or worse to do this instead of just using a 700R4?

    I know you can order a Howell wiring harness and computer for each specific setup (like running a 700R4 or TH350 instead of a 4L60E) but I'm interested to see if there's an issue with keeping the 4L60E and using it in the swap instead... /forums/images/graemlins/grin.gif

    If he is running the 5.3 with the stock injection and computer I would get the tranny and wiring harness that goes with it. It would save a good deal of headache's b/c I think the engine and tranny are run off the same computer.

    The 4L60E is the electronic (controlled by the computer) version of the 700R4 (mechanically controlled). It would be best to get the tranny also, or he will probably have problems when the computer cant find the transmission.
