I'm working on tuning my transmission myself and am having issues with getting the 2nd to 3rd shift in T/H mode to listen to the values I enter.

Given stock tires and 3:42s the value I have set for 0-17% throttle input is 1025 on the output shaft speed. (Translates to approximately 30 mph)

For some reason the truck will still shift to 3rd at 18mph or so at light throttle.

The values are exactly the same in "normal" shift mode and the transmission listens to the values exactly.

Are there any tuners here that could provide some input?

Thanks in advance!
