e it sucks its hella expesive to get it part by part i would just bu a new oneor rebuilt one make sure it has a warranty too cuz i threw the reverse in my trannyand they wanted like 700 dollars for a part ansd a new or rebuilt one is like 800-900 so go with the rebiult or new one its cheaper and less headaches in my opinion. i know cuz i just ot mine back rolling today.

when doing a rebuild, you usually inspect all thrust washers, bearings, shafts, gears, and case assembly. you usually replace all seals and all synchronizer blocker ring assemblies. rebuild also includes measuring clearances and backlash as well as making adjusments to shift linkage and clutch (if not hydraulic) once the trans is reinstalled.
while its out, you might as well go ahead and do a clutch job on it as well. clutch disc, pressure plate, flywheel, release bearing, and pilot bearing.
cokewhite is right though, rebuilt t-5's are pretty cheap. you just have to remember to get the right one for this application (or you could get one out of another application so long as you can get it to bolt up okay.) there are borg-warner t-5's in everything from 4-cyl s-10's to early 90 model mustang 5.0's to 4th gen camaros. they all have different gear ratios for each gear, but 4th will always be 1:1 and 5th will of course always be overdrive.
many people go with lower gears in rear to increase torque to rear wheels, but you could also get a t5 that's geared a little bit lower to accomplish the same task. plus, like cokewhite said, when you purchase a rebuilt unit it usually comes with some kind of warranty that you don't get when you do it yourself. also, these things are rebuilt on an assembly line by people who do the same thing all day long, and are usually QC inspected by an ASE certified professional. if you've never reconditioned a transmission before, this may be your best choice.

for comparison in shopping for gear ratios (***remember that replacing the OEM M49 t-5 with one that has different internal gearing will throw off speedo, odometer, and pcm the same as if you changed rear gears.) here are the gear ratios for the automatic trans (4L60E, RPO M30) for comparison:
1st: 3.059:1
2nd: 1.625:1
3rd: 1.000:1 (direct drive, same as 4th in t-5)
4th: 0.696:1 (overdrive)
REV: 2.294:1

mfgr service manual does not provide gear ratios for either the M49 5-speed or the MM6 6-speed manual trans, but they may be in the tech database on this site...

***remember, i mention using different gearing than stock only as a possibility. personally i would not put a trans with different gearing in my personal car. if you do go this route the pcm will not receive an accurate signal for vehicle speed because its programmed for the M49's gearing. however, this IS one way besides changing final drive gearing to increase torque supplied to the rear wheels.

if you do decide to rebuild yours, the t-5 is one of the easier manual trannies out there to go through. just get a very detailed, very comprehensive reference guide before you start. clearances and end play are critical to proper operation and long trans life.

edit: and take your time when doing it. nothing sux worse than to go through the trans, get it all back together (yea! no missing/extra parts!!!), put it back in, and then go to drive it only to find out that you used the wrong size selective shim and the thing behaves worse than it did to start with... like my middle-school woodshop teacher said (ad nauseum), "measure twice, cut once."

when looking into rebuilding or buying a rebuilt tranny, it is also a good idea to have it race-prepped, just to make sure everything will work well, and also get it lightened too. replace the heavy stock units with lighter aluminum units so more power can be put to the wheels, as well as not having to use as much of the clutch to grip everything.
