Hi guys,

Just trying to get some info for my dad. He's not very computer/internet savvy so i'm doing some legwork.

He's got a 68 F100 pickup. 360 Fe motor, but a tricked out 390 (from his previous F100 project) is going into the truck.

The question he has is pertaining to the 3 speed column manual with overdrive...

The number cast on the Tranny (actual its on a hangtag, similar to the tag on the rearends) is: C8T3AS-1. It is hanging from the bolt on the bottom of the second fork.

It's a SIDE LOADER transmission. And we're looking to get any and all relavent info/specs on the tranny. Gear ratios, Torque capacity, etc.

There are 2 electrical "pieces" associated with the tranny.
-One connects to the same gear the speedo is driven from-except on the passengers side at the back of the trans.
-The other is on the drivers side near the back of the case before the overdrive(what would be the tailshaft). This is an electrical motor/device similar in size and shape to a riding lawnmower starter...It goes into the tranny housing. At WOT this activates a solenoid switch at the firewall...but not sure what it is?

I can get pics but it will be a few weeks before that will happen (Thanksgiving probably)

Any info is appreciated. Thanks!

The governor will screw in, it allows you to go into OD above and out below a certain speed. On the left mounted with 2 bolts is the solenoid which engages and disengages a pawl, it is controlled by the governor. After you remove the 2 bolts rotate the housing 90 degrees then pull out of the box. I wouldn't hot rod that box as it will break and parts are getting rare.

Thanks Beemer Nut. Any idea as to how rare this transmission is?

 

Sorry, not a clue. Check the early 50's to 60's truck and car forum as that's the era of the box. That a BW T86 box with a R-11 or R-12 OD? The side can be plugged off then add a Jeep top shifter. Check also with a Jeep 4 x 4 shop for older like WW 2 up, not Jeep dealers. I was agressive in a Ramble American years ago with a hotted 6 that ate T-96 boxes and hurt T-86 boxes, both had OD's.

Lightning247: Search under my name, banjopicker66 for detailed informaion on the Warner T-85N overdrive transmission. I did a number of posts with detailed explanations on it. You may need to restrict the search to the '61 - '66 forumt though, as that is usually where I spend my time.
Good luck and post back with any questions.
