“T96-1A 3 Speed With Overdrive Transmission R10B-1E Jeep Willys transmission with a spicer 4-9-67???”
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.

UPDATE: Here is a brochure and some directions/schematics for the rare Sierra Dana 20 Overdrive.
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”
Roy spotted this ad.
“This is a Willys Jeep Dana Spicer model 18 transfer case. Has 1-1/4″ intermediate shaft
Includes the attached overdrive (Borg Warner or Studebaker?) it is not a Warn/Saturn OD
Call 6-6-1-7-2-2-9-7-9-6 between 8AM and 9PM only”
Not a bad price for a column shift T-90 and BW Overdrive. The Engine is seized.
“THIS IS A F HEAD ENGINE IT WAS ORIGINALLY OUT OF A 62 WILLYS WAGON 2WD IT IS JUST A CORE AS IT APPEARS TO BE SEAZED UP BUT HAS A 12 VOLT STARTER GENERATOR THAT CAN BE USED ALSO ON A L HEAD ENGINE THIS IS COMPLETE FROM FAN TO TRANSMISSION
TRANSMISSION IS A FACTORY COLUNM SHIFT 2WD TRANNY WITH BORG WARNER OVERDRIVE ENGINE TRANNY COMPLETE AS PICTURED $150.00”
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”
Note the SM420 + adapter +TC +overdrive (studebaker) for only $600.
“Stuff that needs a new home:
I 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 20. Here’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”
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.”
