What you need is more miles on the truck so that the transmission can adapt. If you would like to drop it by my house and leave it for a few months I'll take care of the problem for you.

Alternatively you could drive it hard and make it adapt. For some of these there is a fast learn mode that the dealer can put it in. In that mode it adapts faster than it normally would.
