I have a 92 F250 with the 460 and Auto w/overdrive
I just bought the truck and noticed it shifted hard (like a shift kit) Today I took the truck out and drove for about an hour, before I got back home the transmission did some strange things. While driving at about 55 I came down a hill the trans felt like it went into neutral and would not pull at all until I got down to about 15 mph (I could rev the engine and the tach would go up but the truck did not respond) after it got down to about 15 it started pulling again. It did this two different times. The speedometer does not work so I am guessing at the speed. Any help or ideas would be greatly appreciated.
