You need a shop manual. I'll say that pulling the trans is much easier- disconnect the driveshaft and speedo cable, remove the shifter and all the linkage, take the bolts out of the trans mount and remove it (support the trans!) then remove the distributor cap, take out the four bolts that hold the trans to the bellhousing, lift the engine slightly, pull the trans back and roll it top to the right. Keep working it back until it's as far back as it will go then start letting the engine down. As it comes down there will be one spot that the trans input will clear the bellhousing, then slide the trans forward and out. Not much fun unless you have a trans jack. It's not as heavy as an auto is, but it's still plenty heavy. Watch you fingers.
That's the rough version. the shop manual has the really easy way.
