Anyone running this on a built transmission? I have a BD-Power Trans. Will it work or would it mess up how BD has the Trans. setup? I imagine it would be fine...

I sure would like to have TAP Shift on my 06/07 Kodiak with the 6th speed. Drove a LML from Seattle to Oklahoma and back with it, sure made for easy living in the hills.

More of an annoyance in the mornings but it was worth the added strength to me to just ignore it. Right now, no one has a fix for it and honestly, i think alot of guys are not worried about. youre not under power to kill parts.
So a hard 2-1 downshift with alto G3s is somewhat normal? I've built 3 trans with them in C3 and my personal truck has a hard downshift when you first drive it. None of the other trucks do though and all three have the same setup.

Finally swapped tuning and am enjoying it greatly! 6th gear comes in around 57mph slowly accelerating. Holds the higher gears even with more throttle input which even with my build is still great. Besides the stupid Allison cold shift strategy hanging the gears too high, the shift timing seems perfect and my half throttle 4-5 flair has gone away. The transmission may be getting weak but until then it gets the job done!

Also just noticed something this weekend that I can't remember if it was mentioned. But there is a 2nd gear start programmed into the strategy when selecting 2nd gear. Flipping sweet!

does it actually start in 2nd or do you feel it quickly shift to 2nd soon as you touch the throttle?

It starts in first then jumps to second touching the throttle. The 2-1 downshift still seems to be normal when coming back to a stop.

ok, 10-4. i thought maybe Josh found the tables to make it STAY in 2nd gear at all times even at a full stop (think its one of the things he has to search for when hes bored). the 06-up trucks will stay in 2nd when you make a 2nd gear start tune, its just the 01-05 that do this.

That would sure be nice, I'd daily a second gear start tune if it didn't downshift to first when stopping.
