Hello all.. hope all are well.. you are going to like this one..I had to change my tranny oil.. no big deal..done it 100s of time .. building Harleys and whatever,, this is my 3rd spit had a 65 and a 78,, got hit broadside in my 78 ,,guy was going 40 miles an hour,, and i lived..anyway so I get my big belly under the car and take plug out no big deal.. plug came out fine,, drained it then started to put the plug back in.. it would go only half way,, thought ok just a little burr,, not so.. that SOB plug would only go in half way.. so baffled I get a tap to check the threads.. tap went in just fine..so tried it again no way,, half inch drive,, remember this plug came out easy and it was not cross threaded..I was sure.. put tap back in no issue,, ordered new plug,, same thing half way and that was it,, so I got ****** and went and bought a regular plug with the same thread ,, got it in to about an 8th of an inch.. it quit,,man I am ballistic something so simple.. the threads were straight not pipe type so was the plug.. anyway I put the plug in that I bought which does not have a magnet,, but I got it.. I said self it is going to go or It will just stripe out.. well went to the 3/4 drive and got it.. man i still cannot figure it out all threads were fine..gremblins I guess any body else??
