Ok guys i got some questions.
First off i have a built transmission, so it shifts plenty hard.
While in tow/haul 1-2 shift is too hard.
If i copy table D0701's Normal numbers to the Performance Column shouldnt that keep the Part throttle shift speed the same and only change the Base Pressure?
What im tryin to ask is, How do i get Tow/Haul to shift the same as Normal?

And with your shift kit, make sure desired shift times tables are zero'd out.

0'ed Shift times was done before i got the built tranny.
I just know T/H works great on the back roads and stuff so it wont keep shifting. But if i come to a stop sign and take off 1-2 is pretty rough... Too Rough.
Thanks guys!!!
Im fixin to go try this and keep goin on the AutoVE tuning..
I didnt know AutoVE took this long, its hard to hit some cells with the roads the way they are around here.
