When you get a chance to get a switch they are easy to put in. Just screws out & back in. If you cant find one new just about most of the mopar auto tranny switchs may work even if its a 727. Not 100% sure on that but I think its right. SO it would be easy to get one at the pick & pay. But it should be no problem to get a new one I just havnt bought one in awail to know if they are still available. There is a metal gasket that goes on the back of the switch ( slides over the threads) that you want to be sure goes back on so that fluid cant leak out. A bit of RTV on the threads wouldnt hurt either.

If you find you just cant buy one or find one in the junk yards let me know I probably could dig one up out of the basement from one of the trannys I have stored up & mail it to you. If they still sale them new they are cheap.

Any 3 prong torqueflite switch will work. They are all the same, 904 or 727, any year, if it is 3 prong. Still available new. When you change the switch, put a drain pan under the trans, you will loose a little fluid. DO NOT put sealer on the threads. The switch must make a ground connection to the trans case. After you sre done and the trans is warmed up, check the fluid level, and add a required.

I dont know Charlie, Mopar & other OEM manufactures have been putting sealer on the threads at the factory even on the across the counter sensors sold new in the pack for years. They come with the sealant on the threads when you break them out of the pack. Even sensors that give a resistance reading to gound like a water temp sensor they put it on it. I cant see any sealer type giving a problem with this. If anything it might even protect the grounding on some sensors like ones that go into water jackets and have a tendancy to rust or corroad.

The only sensor I have seen that you dont what anything is the O2 sensors & RTV but then they use antysieze type on the threads (which is not a sealant) just to help it form gauling.

Certain things need sealer. But I don't like RTV as a thread sealer. On most of the sensor/senders that have sealer on them, have a taper pipe thread, on no seal/washer/"O"-ring. On something like these, I use locktite thread sealant. I also use this on the manifold studs that go in the head. The neutral safety switch is a straight thred and has a seal washer on it, so sealer is not neccessary. I hate to work on a engine, etc, that has been put together with 5 tubes of RTV. Remember the "Brill Creme" hair tonic comercial? "A little dab will do ya."

Ah, now you're dating yourself Charlie. I'd bet fewer than 20% of the guys on here have ever seen those commercials. Can you even still get the stuff?

Gee, I don't know. Give you an idea, I ran my first drag race, in 1958, at Montgomery New York. It was NASCAR sanctioned.

In 1958 I was in the 7th grade and was probably using Brilcream and watching for Burma Shave signs when we were traveling.

WoW guys. I was a ASE cert tech for 15 years, and then ran my own performance shop for a few years before I got dissabled. Worked for many small shops before all that for about 10 years. And you guys still have a few years on me. All though I dont feel young with the injurys and all you guys are making me feel younger, keep it up I need all that I can get, lol.

There are a few of us old farts on this site, and I would go so far as to say there are a many slant racers over 50 as under 50, with some of us on Social Security.

Hey Jess, Just remember the quote in David's signature.
"growing old isunavoidable, growing up is strickly optional."
