I have a 92 F150 4x4 302 and a 5 spd. 1st thing in the am it shifts fine but after it warms up it is hard to get into gear. If you put it in 4th 1st then it will drop right into 1st. If you shut it off it will go right into gear. Seems like the clutch is not totally disengaging. The old guy i bought it from had a new clutch installed 2 years ago and only put 1000 miles on it since. The truck has 94,000 miles on it. My thoughts are either they re-used the old slave cyl. and it is bad or maybe the master cyl is shot? It doesn't leak any fluid.
