Granted my only experience is with DSM transmissions, but they were all wheel drive with a lot more going on. You need a 20+ ton press, a pile of bearing pullers (preferrably from an OEM tool kit), an inch pound torque wrench, a big ****ing hammer, a complete metric set of everything, and balls of steel.

I got my AWD 5-speed manual transmission all torn down in about 2 hours (we're talking AFTER the transmission was out of the car and on a workbench.) Inspected everything and I needed to replace a LOT. All six synchros (reverse, people), 1st gear, 1st-2nd shift hub, and all the bearings & shims. (the bearing underneath my 1st gear let go and ground itself into the case. ) I don't know what Honduh prices are for transmission internals, but that list ran me ~$500-600 which is probably more (parts wise) than you'll need. ALWAYS replace every bearing, race & shim, along with every synchro. They're cheap, JUST DO IT. Bearings with races were $5-10 each, synchros were $15-25 each, shims were $1-2 each.

I had help from an ASE mechanic putting it all back together, took us 6-8 hours but we were doing several transmissions at the same time. Shimming was a pain, just had to go by factory specs and play it by feel. Got it all back together and went for a test drive. 200 miles later 3rd gear shattered, sending shrapnel into the center differential, intermediate gear, and then back through the front differential for some more fun. Evidently 3rd gear had a micro-fracture in it, invisible to the naked eye, and it gave up the ghost. Oh well, what can you do.

Tore it apart again on my own, assessed the damage, cried, killed a six pack, called to an online dealer, ordered more parts, and waited a couple days. 3rd gear & the intermediate shaft were $400 if I remember, it's been a while. Started rebuilding it on my own, messed up when assembling the 1st-2nd gear spindle (put the shift hub on backwards ), disassembled it AGAIN, rebuilt it AGAIN, and got it all back together in a total of 4-5 hours. Gave it a little time to let the anaerobic gasket maker to set, then drove home and threw it in the car. Yes I was nervous, but damn it I felt good.

2000 miles later, I still make a small prayer every time I shift, but she's going strong.
:driving:

Long story short, can you do it? Sure, maybe, possibly. Should you have help? YES. If you don't have a master mechanic handy, you can yank the transmission yourself (pretty easy, gravity is on your side, getting it back up is the bitch) then haul it to a tranny shop or ship it to a friend. This will save you labor on removal & installation.

If you aren't capable of that, call your favorite stealership and make an appointment for one ass rape, no lube. Be prepared for $400+ to remove & later install the transmission, $1000+ just to rebuild it, plus parts.
