Snap-on sells a long extension that allows you to enter at the tranny tail shaft.The one end is a 1/2 inch drive and it tapers to a 3/8 inch drive at the socket end. Use a good quality (nothing that says Taiwan on it)17 mm wobbly for the tranny bolts and a plain 1/2 inch wobbly with a 10 mm allen socket for the starter bolts. This long one piece extension gives you the 1/2 inch breaker bar muscle you need at one end and the 3/8 inch flexibility you need at the other end.I hope snap-on still makes the tool;I bought mine about 25 years ago.The key is to use good quality tools like snap-on which,in my opinion,is the second best quality made tool in the world.Hope this helps.This extension makes the job a cakewalk.

Good luck,
Peter
