Blaine spotted a discussion at the Ford-Trucks.com forum on Auxiliary transmissions that included the rare Warn Auxiliary Overdrive. A user named “38 Coupe” shared a bunch of smaller Auxiliary transmission documents that included a Parts and Instruction manual for the Warn AO. So, here it is, along with some photos of a Warn unit that was for sale in April of 2015.

overdrive-oh

“29 spline Warn Saturn Overdrive – will fit a T-90/Dana 18 transmission/transfer case. Run that vintage Jeep a little faster and run with lower RPM’s. This overdrive was recently re-built by Herm the Overdrive guy. It is fully functional. I had it in my FC 150 but could not get the linkage worked out to my satisfaction. Ended up selling the FC (for other reasons) and now want to find a good home for this overdrive. Comes complete and ready to install with everything you need (including a new “special” retainer clip) DOES NOT INCLUDE SHIFTER OR LINKAGE – but these are easily fabricated. This unit has low mileage and shows hardly any wear.”

CJ-5 Parts including Warn OD Ashton, ID

The seller is parting out a CJ-5. The tranny/tc/Warn OD is a package deal at $600. It is the older 30% OD.

Transfer case and transmission with Warn overdrive $ 600 as a unit. the overdrive is 29 tooth. Is an older version 30% overdrive.

T90/Dana18/OD Yuma, AZ $800

• CATEGORIES: OD Saturn/Warn

Appears worth a look.

“This is a T90 transmission, Dana 18 transfer case and Saturn OD from a 1946 CJ2A.
They all shift and turn freely. The only evident issue is that some one beforehand had cut the tops of the original shifters and added these rods. Doesn’t affect the function, just looks dumb.”

• CATEGORIES: OD Saturn/Warn

All rebuilt.

“I have rebuilt t18 transmission ( spent $1300) with Novak adapter to a cj2a dana 18 ( rebuilt) with warn overdrive ( rebuilt by Olympic 4×4) combo that I need to sell. I had this combo built years ago but never completed the project so it has zero miles. I have paperwork on tranny and overdrive but cannot find transfer case paperwork. Have all shifters and linkage for all. This has been in my shop collecting dust for many years but has been inside the whole time. It is currently attached to a ford 289 (zero mile since built) but I may keep that for my bronco”

1980 Overdrive Article from Pickup, Van & 4WD Mag

• CATEGORIES: Features, OD Other, OD Borg Warner/Rancho, OD Saturn/Warn, Old Images
sierra-overdrive

The Sierra Overdrive was designed to mount to a Dana 20.

In November of 1980, Pickup, Van & 4WD Magazine published this article on overdrives, which includes several I hadn’t heard about. This series of article images comes from Christian Harrison (and thanks to Marty Tilford for spotting it). The scans aren’t perfect, but are mostly readable. You can find a similar article at the Four Wheeler Network.

Particularly interesting to me is the Dana 20-mounted Sierra Overdrive. Willie Worthy of Four Wheeler was involved in the development of it, but noted that a lack of capital doomed it.

PTO/OD/TCs/Parts Ferndale, WA $1500

• CATEGORIES: OD Saturn/Warn, Transfer Cases

Here’s a neat combo.

“Very rare 29 tooth warn overdrive unit with ultra rare adapter for Ramsey pto. Included is the Spicer 18 tranfercase (mostly complete with dual levers), Dana 20 transfercase (disassembled but mostly there), Warn 29 tooth overdrive unit, adapter to Ramsey pto winch, Ramsey pto winch, shafts, pillow bearing, Ramsey winch, cable and misc pieces. Note: I believe the transfercases are 26 tooth and that is why I didn’t finish project. Also these pieces have been sitting about 10 years in an uninsulated shop (surface rust is on most everything). These pieces were working when removed, but that 10 years ago. I didn’t notice any broken teeth but you need to inspect before buying. I believe almost everything is there, but sitting in shop for ten years I may have misplaced some things. Will not part, complete sale only. Price is firm. If you need more picks please email me and I will send them to you.”

Warn VS. Husky Overdrive

• CATEGORIES: Features, OD Other, OD Saturn/Warn

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).
