I'm having some drivetrain work done on my 1970. It has a M20 in it and the guy mentioned that the neutral safety switch has gone bad (along with other problems). He mentioned that it's hard to get and wants $112 for one. Seems steep to me. Are they that hard to get?

That is steep. I'm sure there's a way to set up a safety switch on the clutch pedal. I'm thinking that rigging a brake light switch into the starter circuit would do the trick. (Of course the brake light switch would be hooked up to the clutch pedal.)

Is he talking about the clutch pedal safety switch? I dont remember a neutral safety switch on my 70 with a m21..it had backdrive linkage to the steering column for the reverse lights, and the safety switch on the clutch pedal. If it is that switch, I would try and get one off a different vehicle, say a 70s pickup which is common in junkyards. Otherwise scour the swapmeets, they are out there.

I should probably check. I sent a e-mail to DZAUTO to see if there is such a thing. If the guy is only talking about the clutch pedal switch the only think wrong with it is the plunger is outside of the switch. All I need to do for that is reinsert it.

I just went throught all of my manuals. It does show a neutral safety switch that is combined with the Backup light switch, but it has a comment that it's for auto trans only. I know this switch is activated by a rod from the transmission but I think that all it does it turn on the backup lights and prevents you from removing the key unless you are in reverse. I need to find out exactly which switch he's talking about and they aren't open again until Monday. It'll drive me crazy until then. Oh well.

The neutral switch is located on the pedal bracing above the clutch pedal,with the accuating lever attached to the clutch pedal.On the factory manual shift depressing the clutch operated the neutral switch.112$,sounds like he is trying to pay is rent off you alone.A switch off a camaro,nova,gto,chevlle,cutlass,impala and possibly pickup's.67,68-72,73 should work.

Dave,
I read your email first. I don't know if it is still available, but the part number is (or was) 3983966. There HAS to be a ton of people out there who have disconnected theirs and will sell you a good one. Go to the ad section here on TC and place an ad. You'll probably get several responses. I don't know if 71-2 will work, but the book shows 70 to be by itself.
And yes, a neutral safety/backup switch is for a car with auto.

I have a 73 M20 and it has a switch that is activated by the shafts that come out of the tranny. It is built into the plate that the shafts come thru. I always thought this was a neutral safety switch. I would be happy to know that it is a reverse light switch. Does anyone know for sure?

I bypassed the clutch safety switch in all of my Chevelles. I figured I was smart enough to take it out of gear or push in the clutch when I start it and no one else gets a key (except the wife and she is smarter than me).

I bought the switch from Chicago Muscle for 50.00. THe 69 switch is not the same as a 70.It hooks up to the clutch pedal that is why you have to push the pedal to the floor in order for the car to start.

Don- If the switch you are referring to is on the front lever of the side cover, it is for cars with the Transmission Controlled Spark system, known as TCS. It allows vacuum advance only in 4th gear after the engine has warmed up.

Try looking for the switch at your local GM parts counter. You'd be surprised at what is still available.
