Yes, you cannot get into reverse without wiring that switch. I believe that you just apply 12 volts when you want to get into reverse. You could go complex and hook it up to a speed sensor switch so when you are at say 2 mph or less the solenoid will allow reverse. I am going to hook mine to a switch on my shift handle.

Wow, that's news to me...and I've been shifting my T56 into reverse for months now without the lockout switch wired. It takes a little extra effort but is not a problem. Ideally it's best to wire the switch as originally designed, though. Just too many other projects in the way.

I think it was Ben Franklin who said "Better to remain silent and be thought a fool, than to speak up and remove all doubt." Words to live by GoFasterFirebird.

Dittos to what kevinc said. I've had mine in for a couple of months now and just force it past the solenoid, it's not hurting anything. Actually I prefer it that way, you have to make it a conscious effort, there is no doing it by accident.

Is there a way we can take the solenoid apart? last time I looked at mine was a year ago (still in the garage) but I thought it could be done, what do you guys think?

Take the solenoid apart? If you mean remove it I'd say very bad idea. I would imagine accidentaly hitting reverse at those speeds would be very bad for the tranny

soulition for lock out

I found an article in chevy performance that tells how to wire it to a button. I'm going with that. I can't wait tell it is running.

When I hooked up my solenoid I solderd a wire to the back of the cigarette lighter. Then ran the wire down inside the consol, through the shifter and to the solenoid. Its easier than running a wire all the way to the fusebox, and its still protected by a fuse.

Ahh yes, I guess you can just force it past. I tried it on my new aftermarket one and I didn't apply that much effort. Now that I moved the solenoid once it seems easier. Kevinc, I appreciate the salt in the wound. Just b/c my car is faster doesn't mean you should condemn me for that.

I'm gonna wire mine to my brake switch, so I can only shift to reverse when the brake is applied. I've already got a button on my shifter that goes to my line lock.

my 97 formula you had to force it into reverse. Every car I have driven with a t-56 you had to put a little bit of preasure to get it to go into reverse.

What amount of time can the solenoid be on before failure? I am asking what the duty cycle of that solenoid is. I am thinking that maybe a brake switch will allow it to stay on too long. Just a possibility..

I don't know what the duty cycle is, but in stock apps it is on any time the car is below 5mph on the speedometer. I plan on finding a way to hook it into the VSS somehow.

Wired mine to the Hurst T-handle switch along with the line lock (see Kevin91Z) - I just hit the button for either line lock or reverse... I'm never doing the same thing at the same time so it works for me.

t56 lock out

i am just leaving it for now as i have alot of other stuff to do on the car eventually i will hook it up to a button . I dont see how any one could shift into reverse accidentally. you really have to push it over and up.

I don't see how you could hit reverse accidently if you leave the RLS completely disabled either. What we were discussing was what you have to worry about when coming up with a scheme to turn the RLS on and off.

Since I will have easy access to the VSS signal in my car, it's simple enough to run it through a frequency counter and then enable/disable the RLS based on that.

Of course, the term "Reverse Lock-out Solenoid" is actually not correct; it's really a "Reverse Enable Solenoid"... but I digress...

Not sure about the reverse lockout, but I was able to match up the VSS and reverse light connectors in the electronics section at Pep Boys. VSS matched to a "horn connector" and VSS was a standard 2-pole male WeatherPak.

Just draw a picture of the connector shape and the locations of the pins and give it a try.

The reverse lockout solenoid connector is the same as the CAGS connector. I got them both from GM but I don't remember what the part number was.
