Hi i have a 1991 Ford F150 with 90,000 miles. I was wondering if you have heard of this before im sure its common, anyways. I was driving and it started to stall in 1st gear and i quickly switched to 2nd gear and then i acceleratred and it went no where. i pullled off into the side of the highway, and i would try every gear and it would get into them, but when accelerated it went no where. almost like the driveshaft has dropped but its still in tact haha. Maybe the hydrualic slave unit for the clutch? not sure. Please help in any way possible. The clutch is new within a year or two.

Sounds like the clutch is bad.If the slave cylinder were to fail you would not be able to shift it out of gear.It would essential be stuck without a clutch but you can get from gear to gear . so I would start with the clutch itself.

Suggested Repair

Start by inspecting the clutch. Because the transmission can still be shifted between gears, a failed hydraulic slave cylinder is unlikely; a bad clutch is the more probable cause of no movement under acceleration.

Conversation Summary

The owner of a 1991 Ford F-150 with 90,000 miles said the truck stalled in first, then selected gears but would not move when accelerated, despite an intact driveshaft. The clutch was replaced within the past year or two, and the owner suspected the hydraulic slave cylinder. The expert said a failed slave cylinder would prevent shifting out of gear, so the clutch itself should be checked first.
