Just thought I ask for some input I went to pass a truck the other day in my 95 f150 6cyl 5spd and third an fourth gears weren't there and they haven't come back I can put the shifter into third or fourth with out pushing in the clutch an they act just like neutral any ideas?

 

I would crawl under her and make sure that the 3 4 linkage rod is ok. If so, then there is an internal problem with the shifting fork or what ever they use inside the trans
