We're keeping an old Dodge 1985 2.2 Turbo running and was forced to replace all the A-413 tranny pans due to corrosion. Pans are now dry as a bone. BUT--there's always a but-- The Governor Pressure test plug is leaking . Put on a few drops of locktite and managed a few easy turns but still leaking. Is it possible to fix this kind of leak without draining the fluid again? Since its is only under pressure when in gear, can I remove the plug engine off, clean the threads, wrap some Teflon tape around it and put it back in without losing much fluid. Need some experience here which I don't have. Thanks.????
