Expert:  JOHN aka Eauto replied 5 years ago.
Its really cut and dry unbolt the tranny drop the drive shafts, drop the starter and the exhaust remove the tranny lines and linkages, The upper bell housing bolts can be a knuckle buster but its a pretty basic job
Customer: replied 5 years ago.
First I read that you did have to remove any exhaust.

There are two support the first one is easy but there is another cross member by the rear drive line that look very difficult to remove. do you have to remove this or will the tranny side back and then fwd.
