Reverse switch T 19

I have swapped a t19 into my CJ. there is a two pronged switch? just to the left and down from the shifter. I have presumed all along that this was the reverse switch. The ohmmeter shows that the switch is closed no matter what position the shifter is in. What is this switch and is it broke or what?

It's the reverse switch. I bought a pigtail from lmc and spliced it into the harness.
Can't remember if it was opened or closed. Can't imagine much could go wrong with one.
Also bought the stock shift boot from the 6.9. Made my own cover plate out of 16 a gauge.

Sounds like the reverse switch by the location you described (should be the only electronic device on the transmission).

By closed, do you mean you are getting continuity across the two posts all the time?

Are your reverse lights staying on all the time, or not coming on at all?

You could try removing the switch from the transmission and wiring to do a bench test. This would help determine if the problem is with the switch or something else (seems more likely it would be wiring).

Yes, it's the reverse light switch.

The pigtail is a pricey little bugger, if I recall correctly.

thanks for the input guys. the wiring is not in place yet as I'm nearing the end of a frame off. Just tested the switch as it sat, before it came time to hook it up. Does anyone Know what to tell the parts man as to what make and model of truck that this would be found in. The PO said it was from a ford grain truck. 1970's 80's? F450? 750? If I just tell them it's a t_19 they'll say HUH?

Wolf,

Here's where I got mine.

Like I said, it's pricy, but Amazon will likely get it to you faster than a parts store would.

Hope this helps,

Matt

Pulled one from an 85 F250 big block (think it was a 460). That should work at the parts counter.

Personally I would unscrew the switch and see if there's something obvious as to why it's not working.

The switch is really just a metal ball with a screw behind it that pushes the contacts open. See if the ball and spring are there, then put it in reverse with the switch removed and see if you can see the lever working that's supposed to push on the ball. A new switch won't fix anything if that lever setup is broken.

Now I lay me down to sleep.
I pray the Lord to fix my Jeep.
If I should die before I wake
Roll this POS into a lake!

Amen
