Default Broken Transmission Pan Bolt

Please help!

It appears that I overtorxed the passenger side middle transmission pan bolt and snapped it off flush. Any ideas on removal? Seems like a small bolt to try to left-hand drill or use easy out. Can I buy replacements at Lowes or the like? Pan has been off very recently and bolt should not be under any pressure or seized. I was trying to fix what I thought to be was a mis-aligned gasket or improperly torxed pan leak. Now I have a real problem 😕

Thanks for any solutions!

Is it snapped flush with the case or the pan?, it the pan when it is removed you might have enough to grab. If flush with the case start drilling.

I did the same and had enough of the end of the bolt sticking out the top to get pliers on it and continue turning clockwise to get it to come out the top.

It's flush with the case. Any bit size recommendations?

Thanks

you can sand off the broken piece flush, and then mark the center...
Use the smallest bit possible and work your way up.


I just did this on an exhaust manifold with no issues, nut snugged right up.

Two options I have done in the past:

1. Drill it out. Use a tap and die set (and new bolt) to replace it.
2. (IF the broken bolt area is near the surface) Get a small Dremel (or similar tiny disc grinder) -> Grind a flat groove in the exposed part of the bolt to have a notch for a flat-head screwdriver. (Deep Creep, or similar "loosening fluids," can help here.)

Thanks for the information.

I was able to put some small vice grips on the end sticking out on top and work it out. New gasket and all six new stainless bolts from Lowes. So far no leaks and running and shifting smooth as glass.

Thanks for everyone's help. 😜

Mike-
