To get the top two tranny bolts, I just use a wobble impact socket and extension, with a impact gun spins them right off, you could undo the cross member bolts some while supporting the tranny and make little more room, or nother trick is to start lifting the engine just high enough to remove the engine mounts then lower the engine back down slowly almost touching the pan to the axle. Leaving the hoist hooked up this will give you more room for top two holes also. I usually just stick wobble up there and forgo both those methods.
