I realize the support to tune the TCM for the 6 spd Allison is not out yet, but I was wondering if any of the EFI creators had any kind of screen shots of the shift points yet?

I just trying to find out when my trans is suppose to shift into 5th and 6th along w/ when the TC is suppose to lockup.

My TC doesn't seem to lock in 5th until after I've shifted into 6th and then it locks and stays locked when I slow down enough for it to downshift into 5th.
Is this normal? Another guy said his locks in 5th before it goes into 6th. His was an '06 but I doubt they changed much between the years.

Nevermind, my truck decided to prove me once again today. I did finally manage to lockup in 5th before 6th. I did have it fully warmed up though so maybe that has something to do with it.
