AiSiN trans tuning

Overall the shifting improved after putting about 300 miles on the truck, ultimately still need some adjusting on the tune the 1-2 , 2-3 , and 3-4 shifts are still very strung out, and maybe change up the converter lock up some also.

Had the tune installed today and a total different truck for the better! Going to haul cattle next week and see how it performs.

Got rid of the flairing in between shifts. Gets better with the more miles put on the truck. My truck is actually enjoyable to drive now.

Great Purchase!

I'm running these new Aisin tunes on my 2015 3500HO. Truck shifts and drives so much better. I can't wait to see how it does pulling my 40ft toy hauler. Biggest improvement I've noticed is the 1-2 shift and going on and off the throttle is much more responsive (less dead pedal I guess)

A must have for a truck that pulls heavy. We run a cattle operation and max these trucks out. Biggest improvement is 50-80% throttle where before the aisin was unsure what to do now it’s confident, quicker shifting in every gear with lockup and shift timing that really matches the Cummins power curve. Big thanks to kory/ ppei for putting this together.
