It was a full tranny flush. I haven't checked the mount, but wouldn't that be noticable all the time, not just when it's cold?

feels like something slides back and hits the tailgate.

After flushing my fluid and switching to Royal Purple I noticed the same thing twice so far. Both times the truck was cold, and both times it happened while leaving work while merging onto the HWY... this is only about two miles from where I park it. I had been thinking about switching back to Mercon.

well then..... i think it has to be in the valvebody. sounds like there might be a sticky valve in thr somewhere or mabe a soloniod.. it might be time to invest into a shift kit and rebuild the valvebody while ur there.

I thought about a sfift kit. Had good luck on a '96 Ram w/ one. The tuner said it wouldn't really be worth my money. What do think?

mine was so bad i thought the tranny was fried.i had the pcm flashed by a friend at a Ford dealership and it has never done it again.i have since bought a tuner.
