I was looking at some of my trans tuning the other day and noticed that EFILive 7.4 and 7.5 have the shift pattern changed around. In the tunes made with 7.4 I have shift pattern B 'Tow/Haul mode' modified. But now it shows Tow/Haul as shift pattern D. They still seem to work as they should, so what gives? Was it actually changed or was there a labeling error?

7.4:
Pattern A = 'Normal' mode shifts, when the selector is in 'D'.
Pattern B = 'Tow/Haul' mode shifts, when the selector is in 'D'.
Pattern C = '4WD Lo' mode shifts, when the selector is in 'D'.
Pattern D = 'Hot Transmission' mode shifts, when the selector is in 'D'.

7.5:
Pattern A = 'Normal' mode shifts, when the selector is in 'D'.
Pattern B = '4WD Lo' mode shifts, when the selector is in 'D'.
Pattern C = 'Hot Transmission' mode shifts, when the selector is in 'D'.
Pattern D = 'Tow/Haul' mode shifts, when the selector is in 'D'.

You have them backwards.

Glad you brought this up - I thought I was going crazy when I went to make some adjustments to a tune I had written in 7.4 and suddenly things didn't seem right in 7.5. never looked into it to figure out why it seemed strange though.

It was backwards, I fixed it. Have you done any testing to see what the deal is? Or are you just scratching your head like i am?
I dont think you changed that around looks like you just went from 7.4 to 7.5

Here is how its in my 7.5 build
Pattern A = 'Normal' mode shifts, when the selector is in 'D'.
Pattern B = 'Tow/Haul' mode shifts, when the selector is in 'D'.
Pattern C = '4WD Lo' mode shifts, when the selector is in 'D'.
Pattern D = 'Hot Transmission' mode shifts, when the selector is in 'D'

Must be the difference between the 5 speed and 6 speed TCMs. My first post I checked a 6 speed TCM file, but I just now checked a 5 speed file and it is like you guys are saying.

Mine is wrong on 5spd and 6spd both, has been since I went to 7.5. I even uninstalled and re installing thinking maybe it was a download problem but it's still the same.
