ya... i agree. i'll leave the bolt on. i installed my tranny temp sensor over the weekend and initially didn't screw it in nearly enough (it's hard to see and i was just guessing the amount of torque i was putting on the wrench). it was leaking a bit until i realized it needed to be tightened down way more. based on how much i added last night, i lost about 8oz of fluid. not too bad i suppose.
