the guy who built the trans for my vette said that shift kits are designed to shift hard so the driver thinks it is better, but it's not a good shift and is hard on the transmission.
To do it right he changed some internal programming in the trans.
The vettes trans will go into whatever gear you tell it to, It also does shift very hard on WOT, but putting around it shifts nice.
I would not put a shift kit in anything, much less a motorhome.
I would let Manny update it however.

Don't do it or you could damage your engine. It cost me 2 engines. First one over reved in low gear when I accidentally pulled it into low thinking
it was super. You can't pull the trans into low if the rpm is too high with the stock trans but with a shift kit it will go into low. 2nd one damaged
the thrust bearing from extremely hard upshufts. After this I had Manny remove the kit and redo the trans. If you are a flatlander you may never have
a problem but living in a mountain state is hard on drive trains cause you are always working it hard climbing steep grades while towing.
