I cross threaded one of the tabs on my torque converter the last time I put my tranny back on. Because it wasn’t in a position where I could tape it out and put a helicoil in (without pulling the tranny again) I had to just run a M8 x 1.25 tap right through it which I think just chopped off the top of the peaks of each thread.. Now I have the tranny out again I want to fix that hole.
I’ve never done this before, but I think its just a matter of tapping the hole out to the bigger size and then threading the helicoil in. Do I need to drill out the hole at all or can I just start tapping with the larger tap since there are still threads there.
Do I just use a tap one size up?
