Late 70s Early 80 QuadraTrac VS 4WD

Hoping to get some clarrification here from Yous experts!

Is Quadratrac full time four wheel drive?

My 1985 J10/258/Auto has a lever under the seat for engaging 4WD (I think), is this QuadraTrac? It used to have a vacuum switch mounted under the dash too.
What set up is this and how does it work?

Thanx in advance for any help!

if its an 85 it was most likely an np229 swapped to an np208 with a flag shifter near the seat, this offered 2hi 4hi (on road) and 4low lock. you most likely have an np208 or np219. If you have a 2wd 4hi lock and 4 low lock on the lever than its an np208 and np 219 was only used in 80 and some 81's but was still branded as "quadratrac" it had 4hi (on road) 4hi lock and 4low lock

Most likely you are close but very likely wrong. This is not that helpful. Try again.

All quadratracs are full-time transfer case (no 2WD mode). The original(73-79) "real QT's are Borg Warner tcases, the later 80-82 also called QT's (marketing label) are New Process NP219 tcases. In an 85 GW most likely it's a NP229 tcase(Selectrac) which is a full-time/part-time tcase (it has a 2WD mode) The 2wd/4wd selection is made via a dash vacuum switch and associated vacuum plumbing. The H/N/L range functions are selected via a mechanical flag lever mounted near the floor off the side of the tunnel. Only other tcase option in 85 was the part-time NP208 tcase(Commandtrac). Mounted behind an AT all the 208 modes (2H, 4H, 4L, N) are controlled by a mechanical flag lever similar to the 229's H/L floor lever. A factory 208 will also have come stock with manual unlocking hubs. I'm betting yours came with the 229 vacuum tcase but folks get scared silly with vacuum stuff a 208 swap is common. If yours was swapped the vac dash lever has prolly been removed and the orig H/L lever now controls all the functions of a 208. Crawl under your car an look at the round tag on the tcase it'll tell you what it is. If missing look for vacuum lines going to a vac motor mounted on the tcase.

Really

Assuming is not good. Crawl under the truck look for the round red label on the back on the transfer case & read it. Probably a 229 maybe a 219 or 208.
Most likely & original 229. In reality it could be anything. There is no other way to know what you have without looking. We could guess all day. What would probably come of that is a fried T/C. Seriously it's not somethig to guess at.

If you can't make it better why waste your time. No use repeating the orignal mistakes. I'm to old to push it that's why.

I was on my way out and didn't get in the low range flag shifter for np229's and 70's qtracs, with so little time I shoulda kept my nose out of it but I couldnt keep my mouth shut

The 70s Quadra-Tracs in Wagoneers do not have low range.

Not all of them do since the reduction box was an extra cost option. The QT w/o reduction box is the model BW1305. The 1305 with the optional low range was sold as the model BW 1339. Don't know this as fact but from what I've seen I'd bet there were more sold w/lo range than w/o.

I've seen more waggys than not with the early Quadra Trac had low range. My 79 will beg to differ

I almost never know what the heck I am talking about but on this I am sure.

As stated above BW 1305 v. 1339 is a fact. I have a 1339 and it most certainly has the low range. Now time for my shameless plug; the low drive is unbelievable, been stuck many times, but thanks to that lever under my seat I almost always get unstuck!
