T18 won't shift
My T18 tranny in my 85 F150 will not shift, first instinct was clutch but after tearing the drivetrain out of the truck to check the clutch, there is virtually no wear on it. Slave cylinder is leaking a littttttle bit but the mechanic that took a quick look at it said it was still working. She was shifting fine when i left for school, then when i got off the highway i couldn't shift. Help anyone??????

Check your firewall for flex and a crack where the clutch master mounts. Check all the rest of the clutch set up and make sure the motion at the pedal is getting to the throw out bearing.
Next is to pull the top off the trans and see if there is something wrong with the shifter and forks. You should have a removable panel in the floor of the truck so you don't have to pull the box.
