I pulled the gearbox on my 94 ex, and had a shop rebuild it reinstalled it myself. wasnt too hard, I used the haynes manual, seemed pretty straight forward, but I've built a few mustang racecars, and have some other mech skills. If you do it yourself make sure you check your axles,boots, and clutch while everythings out! You dont need any real special tools just a full set of sockets and wrenches, a couple of jacks, and jackstands, maybe a breaker bar and a prybar, a hammer and a punch, hmm... off the top of my head, thats all I can think of.
