i guess my other post didnt make it on. was driving down the road and it shuttered a little bit when hitting overdrive. i was pulling a trailer with a roller on it. dropped the trailer off and came down the interstate about 70 miles an hour and everything was fine. Exited onto a slower road and transmission was acting funny. pulled into a gas station to check it out and had no gears at all. shut it off and it would drive about twenty feet then kick back out. would do this everytime i shut it off. did i burn it up or is something else going on here?
