Hi All,

Im new to this forum so a little intro. I have a 2001 c3 6.0 with a Whipple SC at 6lbs of boost, Wester's tune and a Flomaster mufler. After killing a couple of 4l65s I just finished a 4L80 swap. I drove the truck before I switched the wiring and the tranny shifted fast and crisp but no TC lock up. I finished the rewiring this morning- switched the brown wire with the white one on the trans connector and ran wires from the computer to the front ISS wire A to pin 22 wire B to pin 23 of the RED connector. After a test drive the tranny shifts slowly with some flairing and still no TC lock up. At least the SES light is off now. Did I do the wiring correctly?



Thanks

Steve

 

You did do a segment swap for the 4l80e right?

 

What's a segment swap, did not read or hear that term. If you mean updating the computer for the conversion, yes

 

A segment swap is when you convert the PCM and put an 80E file in it to make it shift right. You should go over my "4L80E" using the search function to make sure you got everything right.
