hey if me and my buddie can pull out a tranny and reinstall it u can do it,just plan to do it over a w/end and get some tools and a spring compressor ,and ask a mate to lend u a hand,
also get a decent jack and jackstands and make sure u do it where u dont have to move it out the way of anything eg your mom needs to park in the garage and your in the way etc,
other than that just take your time and get a haynes manual and jobs a goodun,
