Default Tow/Haul tuning Q's

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?

Copy and paste everything, except what you want to be different (maybe shift points)

Check D0801 as well. Maybe your performance has 0 TM and your normal has some.

Make sure the TM is the same as well as shift pressure and shift time. Those are the things that will make it shift like normal mode.

You're not going to be able to get the shifts to "feel" the same if your t/h mode still shifts at different points. A pressure corresponding to 200ft-lb shift at 3000rpm will feel different than that same line pressure shifting at 4000rpms in t/h.

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

Got it justin...
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.
