I haven’t seen an OD pop up for sale in a while.
“Dana 18 transfer case and overdrive unit. Both work great removed from a 1962 CJ5. Had the overdrive on my 1952 CJ and went from being able to do 45mph to 57mph. Doing and engine and tranny swap so no longer need it. Overdrive is a Warn unit. It is a factory part not a knockoff. Very rare. $600”
I thought this overdrive comparison was interesting. A 1969 article promoted Warn’s Auxiliary Transmission, an overdrive that sat between the transmission and transferase. By early 1970 Husky was promoting a similar sized heavy-duty overdrive that sat between the engine and transmission.
More pics of the Warn Auxiliary Transmission. This one was sold in Nevada in 2013, priced at only $450 (also included tranny & tc).
This one was priced at $700 and sold out of Maryland:
UPDATE: **SOLD** Was $450.
Somebody need this one?

“I got this overdrive in an m38 willys that I bought and don’t know the history of it. It does turn and spin and all parts move. It is a Warn, the data tag says it is a 33-29, but the gear has a 26 on it. It came off of a 18 transfer with a t-90 transmission in a willys m38.”
It’s a good price if in good shape.

This combo won’t last long.
“jeep transmission and transfer case with overdrive only. motor not included $400”

“For sale the ultimate early CJ5, CJ6, CJ2, commando and CJ3B combo an upgraded t90 transmission with a twin stick dana/ spicer transfer case, with a warn overdrive and a Ramsey pto . Also included are the parts to remove the pto. This is a great setup and was fully functional when removed. The guy I bought it from was doing a diesel swap in his cj6 and couldn’t use this setup. I was going to use the transfer case and overdrive in my cj5 but it turns out the t14 trans I have has a different spline count so I can’t use it. Looking to get 1000 obo or trade for a warn overdrive for a t14/ dana 18 or let me know what you have. This is a good price as the warn overdrive alone is new over a 1000 and 700+- used”
UPDATE: **SOLD** Was $500
“Recently removed from a Willys Jeep project that I am parting out. All internals in great shape except for the special lock washer, and the end of the 6 spline shaft. The washer and special C clip are available from Advanced Adapters in their installation kit. The end of the 6 spline shaft is serviceable, just needs dressed up. Brass syncro ring and dogs and springs all look good. Planetary gears spin free with no noticeable wear. Original vintage Jeep and International Scout All range overdrive, just needs the washer replaced and installed on your Dana Spicer 18. I did not disassemble the planetary housing any further than is depicted…If you want me to dig deeper into the assemble I can but I don’t think it necessary. This was removed from a Ford 289, top loader 3 speed and Spicer 18 that came out of a running Willys.”

This setup has a Warn and a Borg Warner Overdrive.
“T 90 3 speed transmission out of an 80’s CJ 5 with Warn Overdrive. There is another reduction gear on the side of the tranny. I was going to use this in my Willy’s project but didnt need my wagon to be slow low geared.
Everything is in really good condition, I had the over drive off and it looks brand new inside. Overdrive has all parts which is rare to find, includes shifter and linkage. OD alone is worth the $500.
Looking to sell but not going to give this away, anyone with a old jeep or on going project realizes the value.”
UPDATE: Was $450. **SOLD**
“Warn/Saturn overdrive unit that mates to the Dana Model 18 transfer case.

Unit turns freely and is not burnt up, but needs some new bearings.

This combo may be a good price.
“Dana 18 with warn overdrive and transmission out of a 66 jeep 3 speed. 500$. The overdrive units cost that much used alone.”

“I have a Complete Dana 18 1 1/4″ intermediate shaft with twin sticks.
Disassembled for inspection.
New intermediate shaft with bearings.
New complete seal and gasket kit for it.
Needs assembled, I just haven’t had the time to do it, but I will if someone needs me too.
Also, a Warn / Saturn overdrive unit for the 1 1/4″ shaft Dana 18 transfercase.
Excellent condition. It was in my Jeep and I pulled it off to change the transfercase and noticed the needle bearings in the planatery were showing some wear so I put another overdrive I had back in the Jeep. I have the new bearings for the overdrive.
I have the complete shifter setup for a T90 as well. Could be modified to fit other transmissions if you dont have a T90.
This complete package was a spare for my Jeep, but I sold my jeep a year ago and just clearing out the extra parts I had for it.
Dana 18 twin stick and Warn Overdrive $800 like they sit with the new parts in the bags
or I will rebuild the transfercase and the overdrive with the parts I have for an extra 200 bucks”
