1980 Overdrive Article from Pickup, Van & 4WD Mag

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.

T-90/TC/Warn OD/BW OD Las Vegas, NV **Status Unknown**

UPDATE: Status Unknown. Was $500.

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.”

Dualmatic Overdrive Elkton, VA **Status Unknown**

• CATEGORIES: OD Borg Warner/Rancho, Transfer Cases, Transmissions

UPDATE: This was priced at $1100. **Status Unknown**

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

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.

“willys transmission transfer case and electric o.d. and adapter plate to bolt a ford 302cid or a 289cid bell housing too transmission is a t-90 3speed and the transfercase is a t-18 300.00 206-948-3213”

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

• CATEGORIES: OD Borg Warner/Rancho, Transmissions

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

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.”
