Looking for help. We have an 83 FJ60 4 speed that hasn't been used for a few years. The clutch had been working fine. We just started using it (10 miles) and the clutch suddenly started slipping then quickly quit. Now the truck doesn't move. The truck behaves as if the clutch pedal is always on the floor, but the pedal works normally. The hydraulics seem okay (the fluid is full and the slave cylinder pushes the throw-out arm when we press the pedal) yet we can easily shift in and out of gears as if the pedal was always on the floor. The truck has some rust issues. Any help identifying the problem will be greatly appreciated! Thanks in advance!
