Stripped a bolt hole on my torque converter during install. I DO NOT want to have to take this thing out all the way again. It will tighten to a certain extent and then skip back out at a certain point.
Clearly a heli coil would be best, but is the mounting pad on a toque converter deep enough for one? I'm guessing I would have to cut an insert down in length. Also how far can I drill into it without going into the converter itself. And I'm also guessing I would need to find a bottoming tap to get the threads for the insert deep enough to make a difference. Does any store typically carry bottoming taps?
Also looked at the specs for the permatex thread repair compound. Looks like the recommended torque for a repaired thread is very low.
Any suggestions would be greatly appreciated.

Take it out, cut off the little block, weld the hole up, re-drill and tap it, and then weld it back on in the correct location.
Or, look at this as your big chance to get the new torque converter you've always wanted.

I think that it is, or you can get it to work. If not, it will need to come out for repair IMO.

Consider using a metric sized bolt that's close to the hole size you have, just slightly oversized...just check out a few tap charts to see what size you can go to,...a metric starter and bottoming tap would do the job, no drilling, just tap, and go
