I changed the transmission fluid on my Demon with 727 and found one of the pan bolt threads stripped. I installed an aluminum pan with 2 qt extra capacity and do not have any leaks so far. I did have a leak before I took the stock pan off. I do not like the aluminum pan because it hangs very low and plan to go back to stock pan sometime in the future. But I want to repair that stripped thread before I go back to stock pan. I have heard of helicoils but have never installed one. Is that something a novice like myself can do? Where do you buy helicoils and what size would I need. Someone please educate me. Thanks.
