You get to them one at a time by spinning the crank. Take the spark plugs out to make it easier to turn.
Here is the fun part. When you put it back together, place the torque converter on the transmission input shaft first. Then put the engine and trans together. Then as before, tighten one at a time by spinning the engine over. Much fun.
If you bolt the TC to the flexplate then try to mate the engine and trans, odds are it won't line up. The little splines get wedged on the input shaft for some reason. Don't ask how I found this out.
