I was interesed in the new h and s trans program and was wanting to know how it worked and what all it changed thanks

 

If you haven't found anything else yet, a couple google searches turned up threads in cumminsforum and some others.

 

I have the H&S trans upgrade, if you get it on it shifts a lot quicker, but just normal driving it seems to want to stay in 5th until you give it a little pedal to make it go to 6th. Other than that I like it better than it was before.

 

Yes, gave mine a nice firmer shift and eliminated that horrible 6-5 downshift buck.
