I need any information on a Rocky Mountain Transmission.
What is it worth?
Is it a 3 speed?
What are the gear ratios?
Does it gear up or down?
Thanks in advance!
Need more information, like maybe photos. I think most of them are "Rocky Mountain Six Speed" which are an underdrive, direct drive, and overdrive (sometimes referred to as a UDO). The way they count it is the Ford two speeds times the RM's three speeds equals six forward gear ratios. They and a similar Universal transmission are called a "progressive shift" which means the shift lever moves forward and backward only, no "H" pattern. To go from overdrive into underdrive, you must shift through the direct drive. It also means that you have two neutrals to get stuck in. Added brakes are very important! True for all added model T gear ratios.
I like them! My first boat-tail roadster had the Universal version with the tallest overdrive I have ever seen. It pretty much has to have four-to-one gears in the rear end. My coupe has the Rocky Mountain Six Speed in it. I really have not driven it enough nor needed to do any work on it, so I don't know what the gear ratios are. But I do like the transmission.
As to value, I have seen them from a few hundred to well over a thousand dollars, but do not know if they sold for that. CONDITION on them is very important. Parts are generally not available. If the gears are not good, they are not worth much at all. If the gears are good, but the bushings or bearings are bad, they may be rebuildable, but a buyer would be taking a big risk so therefore still not worth much.
I believe that Rocky Mountain did also build two speed transmissions (I know Universal did. I have had a few). I also know that they built TT versions. So it is really important to know more about what you have or are looking at to answer the basic question better.
Drive carefully, and enjoy, W2
I will get more information this weekend!
