Unusual Auxiliary Transmission … Can Anyone Identify It?

• CATEGORIES: Features, OD Other, OD Borg Warner/Rancho, OD Saturn/Warn This site contains affiliate links for which I may be compensated.

UPDATE: While still unidentified, we have learned thanks to the Dutch_Jeeper on the CJ-3A page that the auxiliary transmission is an “under-drive” rather than an overdrive. He pulled this out of his CJ-3A, then disassembled it.

You can learn more and see more pics here: https://cj3apage.com/Forum/index.php?topic=2318.msg19546#msg19546

1980 Overdrive Article from Pickup, Van & 4WD Mag

UPDATE: Here is a brochure and some directions/schematics for the rare Sierra Dana 20 Overdrive.

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.

UPDATE: **SOLD** Was $1100. 

Eric forwarded this ad. The ad’s title notes the overdrive is a rare Dualmatic overdrive. Herm has rebuilt these in the past. I couldn’t say if he still does or not.

“title says it all, and has cross member. got other tranfers and trannys also”

t-90 with OD Vashon, Wa $250

• CATEGORIES: OD Borg Warner/Rancho This site contains affiliate links for which I may be compensated.

UPDATE:  Price dropped to $250

Overdrive’s don’t appear too often.  Here’s a chance to snag a rare Borg Warner overdrive.  Most of the overdrives that appear for sale are the Warn/Saturn style overdrive, which mount behind the input shaft of the transfercase.  The Borg Warner overdrive mounts along the output shaft (or better put, intercepts the output shaft).  Learn more about overdrives here.

T-90, Dana 18 and Rancho OD — Topaz, Nv $225

• CATEGORIES: OD Borg Warner/Rancho, Transmissions This site contains affiliate links for which I may be compensated.

t90_overdrive_topazI believe this is a rancho BW overdrive.  Here’s a pic of one installed on an M-38a1.  This was posted a month ago.

As a side note, I ran across a thread that suggested Rancho made an adapter plate to mount a rancho BW overdrive onto a Dana 20 tranny (‘herk’ comment 12/07/2007).  I thought that was interesting.  Sierra also made an overdrive for the Dana 20Here’s an article on various overdrives from JP Magazine.

“used for a Jeep. Been sitting around need to get rid of it. Call Randy 775-266-4776 leave a message I’ll return calls in evening. Thanks”

R10H-1 Overdrive Portland, Or $85

• CATEGORIES: OD Borg Warner/Rancho This site contains affiliate links for which I may be compensated.

I’m not positive, but I believe this version of the Borg Warner Overdrive can be used by a variety of 50’s and 60’s vehicles including jeeps with the dana 18 transfercase.  Here’s an article that explores the overdrive issue on older jeeps.

“R10H-1 overdrive, Warner Gear Div., believe out of 50’s chevy? Good condition! $85 or trade for willys, cj parts.”
