There are 6 bolts total which attach the transmission to the block. Three thread into the block and 3 thread into the bell-housing.
BLOCK TO BELL-HOUSING: Two 14mm at the top of the bell housing. 1 14mm just above the clutch slave cylinder (accessible from underneath).
BELL-HOUSING TO BLOCK: 1 8mm for the inspection plate above the slave cylinder (I never replaced this one after the first removal). 1 12mm for the inspection plate below the slave cylinder (important for keeping debris out). 1 12mm below the starter (accessible from underneath after dropping x-fer case and important if you don't want to crack the bell-housing).
Otherwise you just have to remove the 2 bolts in the transmission mount, pull the axles, unhook the reverse-light, unhook the speed sensor, pull the slave cylinder off of the transmission, pull the starter, drop the x-fer case, down-pipe, fore-aft sub-frame brace and support plate, pull the wheel-well dust cover, and then drop it down.
Tips:
1) If you remove the brake-line brackets you can pull the two 17mm suspension strut bolts and tip the hubs out. This will allow you to pull the axles from the transmission without removing the 36mm castle-nuts from the spindles. That is, you can leave the axles in the vehicle and just slide them out of the transmission.
2) Removing the radiator and the lower water-hose makes for more room when wiggling the transmission out.
3) If you have trouble aligning the input shaft with the clutch disk try using a 1/2" socket driver to turn the engine through the drivers wheel well. Always turn clockwise (consistent with engine rotation).
4) Make sure you torque down the transmission bolts a little at once and evenly. If you let the bell-housing get crooked you could do damage to the seals and the clutch disk.
5) The passenger axle can be a BITCH to pull from the transmission but I came up with a slick trick that works like a charm. Get a nice beefy flat-headed screw-driver with a square handle. Get a big crescent wrench and put it on the handle so you can twist it easily. Slide the black of the screw-driver up between the head of the axle and the casting of the transmission. Twist and watch the axle slide away like butter. Wear glasses to keep debris out of your eyes.
