Default No WOT 2-3 shift only after downshift.
Any ideas? Shifts on time for 2-3 except when you hit it in 4th and it downshifts & never makes the shift until you lift your foot off the pedal. This is a 4L60btw.

What size rear tires? Your current & calculated tire sizes need to match.

It's running a 35" tire but to make the VSS read accurate via GPS I think I had to enter 34.25

Try this tune, I fixed your calculated tire dia as that is what determines the shift MPH.

Thanks a lot Russ, I'll try it out and post the results. I see the revs per mile where changed, I just don't understand how they were scaled wrong but I'd love to learn how to tell if they are again in the future on other stuff.
