    4l60e 2-3 Shift

    Hey, 01 ss 4l60e new rpm trans. 2800 vig,3.73 I have my 2-3 programmed at 3500 and 50 mph and it still wants to shift at 6300 and 71-73 mph every time. if I use my tech 2 to control the 2-3 shift solenoid i can make it shift at any rpm i want instantly. i've attached my tune, i must be missing something. thanx

    Is it only not @ WoT the problem occurs? .

    You have "222" plastered all through your Part Throttle Shift Speed-Performance table that could be causing the issue until you get up onto it @ WoT and jump to the other table.

    hmm, looking at another similar tune it has the same :S crazy stuff

    Try changing the part throttle shift table to the same value you want it to change at WOT. Set all your 1-2 shift values to 55, 2-3 to 80 and 3-4 to 155 for example instead of maxing them all out and check that your TPS is reading 100% at WOT.

    See how you go.
