My 727 leaked and leaked...

I could never nail down where it was coming from until I had a 4 post lift installed last week. First thing I noticed after I cleaned up the transmission was seepage at the neutral safety switch. I didn't think it was leaking much by the looks of it though.

I happened to have another, new neutral safety switch at the house so I installed it. I drove the car and checked again. The new switch was also leaking! These switches leak between the plastic and the metal housing.

I bought another switch, as soon as I got it I cleaned it with wax and grease remover then used RTV to seal the junction between the plastic and metal. No more leaks!!! I am amazed at how much it was leaking through the switch every night.

I hope this helps someone else.
