Does anyone know what this is?
This is on a doodlebug I am getting rid of but don't know where it came from. It looks like a high low option? Anyone's help is appreciated.

Whatever it is the bat plug makes it that much better.

That is an auxiliary transmission used on the early AA before the 4 speed transmission was introduced.

Re: Does anyone know what this is?
What you have is called a Dual High, Auxiliary Transmission, after the 3 speed, it takes special adapter to mount it on a Truck 4 Speed. Although it is actually a lower gear ratio, not Higher like a overdrive transmission. It was used in Model AA 131 inch wheelbase frames like Dump Trucks and Log Trucks, a nickname for it is a stump puller Transmission. With your Transmission in Low Gear, Dual High Engaged, Throttle down a little the Truck would crawl, you could walk faster that the truck. I've seen a truck pulling stumps with one, the front end comes right off the ground about 3-4 feet, and the weight of the Truck does pull out most Stumps.
Here is a Link to 322 Thread Posts about it on the AA Truck Forum http://forums.aa-fords.com/search.ph...&submit=Search Last edited by Jazzjr; 11-20-2013 at 07:06 PM. |
