You will need a 727 from a Jeep with an AMC motor, that way you can get a 4WD version of that transmission. you can still find quite a few that were put behind AMC 360 Jeeps.

If you are close to Seattle: AMC 727 and NP219 $175 in good working condition (we pulled them and the 401 for a diesel swap in a '82 Wagoneer) 727 and sometimes 999 (behind the 6 cyls) was used from 80-83 in Cherokee/Wagoneer, 80-88 in Jtrucks and '84 to '91 Grand Wagoneers.

I believe most V8 Jeeps from 1971-1991 should have an AMC engine and a 727 transmission. CJs, Full-Size Jeeps (SJ Cherokees, Wagoneers) and J-series pickups. A Wagoneer is probably easiest to find, almost all 1980+ Wagoneers are 360s.

In the off chance you find a Quadra-Trac 70's Jeep with the Turbo-Hydromatic 400 you'll probably be able to trade that pretty easily so I wouldn't let it go, but they're less common. They might even be desirable to some guys. I think they're way too big to fit into an Eagle and the front drive shaft might be on the wrong side.

I would say go with the 727.   Pretty much bullet proof.  Think about having it refreshened before its put in.

Jeep used TH400 before 1980. Even the CJs. AMC cars got Mopar style trans in '72. Up to '73 Jeep used a Buick Nailhead transmission with an adapter ring to bolt up to Nash/AMC 327 (Gen I), Buick 350 (and 225 V6), Gen II AMC 304/360/401 (designed for flat flange Gen III cranks that were one year only, but they also fit later motors), then AMC cased TH400 '74 till '79 for the Gen III motors.

Two words: Grand Wagoneer.

It's literally the Full Size Jeep.

They're a total unicorn in the Seattle/Portland area but common enough that you can find at least ONE mid to late 80's model and often accompanied by a few other wagons that are typically useless unless you're looking for weird photo worthy stuff like the one I saw in the Portland North lot last weekend. Full Size Jeep, standard axles with 2.73 gearing, 5spd gearbox and a cute little 4cyl up front. :rotfl:

Sherwood has the Grand Wagoneer and last I checked, it's definitely an automatic, most likely the uncommon 727 being discussed here. I tried picking a seat out of it last weekend but gave up after an hour as I decided it just wasn't worth it. The seat covers looked nice though.

I'm surprised no-one has jumped on the working 727 and NP219 I have posted for the same as core prices.
