The Allison being a clutch on clutch transmission must literaly go into nuetral for a millisecond to complete the shift cleanly. If you alter that you will cause a tie up and start binding the clutches. If you do this you will be in 2 gears at once for a millisecond.
So figure a 7,000 lb truck running 500 hp with the pedal to the metal in 2 gears at once for a millisecond and the Alli loses. This is how the splines on the P2 planet and C2 hub strip.

I got lucky and had a job in CA when I needed to get mine done. I paid diesel one way and hotel for 2 nights, job paid the return and hotel. I did it round trip houston to LA and back in 7 days total. All I can say is Mike told me what it would cost, it would take one day (pending the new torque converter arriving), and he was right. It took 2 days as the torque converter did not arrive, but I was informed of this when I dropped it off.

When I called Mike, he only asked 3 questions. 1 - when do you want it done , 2 - how much power you plan on putting to it, & 3 - who is going to tune it. Just answer the questions, and you will be more than happy with what you get back.

Another option is to pull the trans yourself, ship it out on a LTL truck to Mike. When it comes back, reinstall and have someone reset the TAPS.
