Tranny shifting out of od

[dually]

A friend of mine has a 360 1/2 ton 2wd.She says it is out of od and back in.It has almost 300k factory tranny.I didnt get it yet to check it out or get codes.Any ideas? If the tranny is all played out i can pull it.I am thinking the od solenoid in the tranny is shot.What do you guys think? I know it is a shot in the dark because i dont have it yet.....but what's your guess.

I would check for error codes first and check the trans relay...

Thanks will do.I will let you know.It has been a good truck for her.My old 94 v10 had 285k when i sold it ,factory tranny.I like working on her truck because it fits in the garage.
