So I was changing tranny oil in my shee, and I replaced the stock screw(on the bottom of the cases, when changing oil I remove it and the oil flows through the hole, I put it back in and fill with new oil), I replaced it with some super duper screw from ebay with magnetic end. The fuckers said it was for banshee, but I screwed it in and realized that it has a little bit different thread, so I removed it and now the thread in the hole in the cases is fucked, and the stock screw is impossible to tighten - I hope you know what I mean.
How to fix this? Helicoil? If so, which size or type?
Thanks
