If you can't really feel it shift then there is some electronic or hydraulic trickery going on.
By all accounts I have been able to find soft grocery getter shifts ruin transmissions faster as it wears clutches faster than hard shifts.

Thanks. So I am right that disabling the pressure control solenoids so it holds a high pressure is actually better on the transmission? My old trans died shortly after I started messing with it, but at 243K miles I think it was just its time to go.
