Purpose of the Reverse Gear Shifter shaft that sticks out the transmission cover?

[pitpawten]

I was crawling around under my truck and noticed a nice shiny metal linkage sticking out of the rear of the transmission cover. It is item #16 in this picture:



It is designated as the following in TM 9-2520-346-34P:

2520-00-752-1097 7521097 19207 SHAFT,STRAIGHT:REVERSE GEAR SHIFTER

It looks like this is an unused linkage for some kind of add-on item that is actuated when in reverse gear. Anyone know if it was used on our trucks, or was a generic option added just because?

It was originally used before their shift Sprague transfer case

their shift Sprague transfer case

I'm thinking this was supposed to be about the Sprag and Airshift, but there seems to be some noise on the line

Doghead had it right but he's prolly snowed in again and has a dose of cabin fever.

It would appear Doghead is hitting the sauce again. Moderators may want to gently remind him that SS members are expected to scribe their thoughts into coherent sentences.

That shaft is attached to linkages going to the Sprag transfer case. Although generally discontinued in the 1970s, I can vouch that the sprag transfer case was being reused and rebuilt until at least 1985, or at least the National Guard service trucks of that vintage still used them.

Ok so it actuates the Sprag but goes unused on the Airshift hence it sticking out into air on mine

Thanks guys

It's unused on the airshift

You can also use the #16 shaft to contact a switch for reverse lights. Several kits are out there by members for this.

I was thinking down this line too, but with a backup cam, perhaps both simultaneously switched...what's that about brilliant minds?

I was just thinking about how to switch R lights...duh. So who sells these kits?

Was/still am, posting with phone. I used the talk to text feature, then tried to edit it. I did not have my glasses on either. Was not drinking!

I guess it is okay but just for you!
