You can see the bolts (at least with your fingers, "see") from the engine. My advice is (as listed above) get 4 ft of 1/2" extensions and have a helper "guide" them onto the bolts. You'll need a flex head.
As for dropping the transmission a little-----well, you can't do that until you loosen those bolts!!!
You shouldn't have to, just keep it supported and remove all bolts. I broke a cheap 1/2" flex, so be prepared to have good ones, because those suckers are torqued on there hard.
