Transmission Pan gasket oil leak

My truck’s transmission [F350 1999 7.3 Automatic trans] is leaking oil from the pan gasket. When I tried to tighten the bolts, I noticed that the aluminum thread on the transmission where the pan bolts go got stripped(most likely done by the dealer last time I got the oil and filter changed) checking all the bolts, I found 3 more bolts with the same problem. Now, I think I will have to make a new thread however, what size of drill, tap, and bolt I should buy as I understand all 3 should match to provide a good tightening. Or are there any other solutions where tapping to make new thread is not necessary? Also, what is the torque value for the transmission pan’s bolts?

Isaac

Thank you

You should redo all the bolts. Just go the next size bigger on the bolt. Get the tap to match the new bolt. On the package the tap comes in it should tell you what size drill bit you will need.

When drilling out the holes. Keep the drill square to the hole. You do not want to drill crooked holes.
