Then, put a drop or two of Loctite on the bolts and put them back in. If you don't use Loctite, two very bad things will happen--neither which will make you smile.
First, the bolt holes in the tranny case are through holes--as in all the way through to the
oil. Hitting
oil is cool in Texas, but sucks on a tranny. The
oil will work its way around the threads of the bolt and leave a little puddle in your drive way to remind you that you didn't follow David's advise.
Or, WORSE, they will work out over time and start a very unexpected "Agitado" movement in your bell housing that will not be music to your ears.
Make sure you clean off any hanging boogers of the old Locktite that may still be on the bolts. You don't have to clean them perfectly as that is almost impossible. Loctite sticks to bolts harder than Congressman Murtha sticks to Pork.
