While installing the inner cover on my transmission as I was torquing the nuts one started to get loose rather than tight. Yes I was using a torque wrench and it was set for the required 12 ft-lb. Feels like the stud is stripping the threads in the case. Now the question is what is the thread and size of these studs. I believe it is British but I could be wrong. What is the best way to repair the threads? Helicoil and if so what size. I could live with one of the seven being a different size than the others if it comes to that.
