    4L80e custom shifting

    Wondering if anyone has put together a file for a 4 L 80 e that does some impressive shift flows as far as shift points based on throttle position and so on and so forth I would be very interested in obtaining a copy of your handiwork if that would be possible.

    Thanks in advance,

    Robert

    Not entirely sure what youre looking for but if you download bluecat tool you can input all your information and it will give you shift points based off rpm and speed and a few other things

    I did the wiring harness from scratch and am not certain if I'm getting into overdrive, I thought that having a file with shift points and speeds would give me a feel for if I was. I put 12 volts to two trans wires, a pink one and a green one. And then I have a green one left marked as tcc brake.

    That blue cat took sounds terrific, I will be checking it out.

    Maybe you could post your tune and what computer you are using and some more details. Tire size, gear ratio, shift rpm, etc.
