Re: Auto trans shifting hard
it does that for a reason, to get where it needs to be quicker when the computer sees that it's under a load.
you can disconnect the battery cables overnight, and reconnect them in the morning. drive the truck smoothly and with a light foot for the next few days, and the tranny will relearn its shift strategy based upon how you drive it. that might help smooth it out some.
