Hi, I have a Rocky Mountain Transmission that mounts on the rear axle. The shifter says 6 speeds for Ford. So what do I have? Is it 2 gears under or does it have an overdrive? If so what ratio? Are there parts for this unit? Thanks for any info you can give, Scott
3-speed. Parts are where you can find them - swap meets, want ads, etc.
Scott --According to the ad Dan posted, it would be an underdrive--straight through--overdrive unit.
That is like what is in my coupe! Nice units. Universal was the other common brand that supplied a similar item. Both were built in both car and/or truck units. They tend to be easy to shift, compared to things like Warford and Jumbo Giant. But they can also be a bit tricky once in awhile. I had a Universal three-speed progressive shift in my first boat-tail (very similar unit). I used to joke about it having two neutrals to get stuck in. It can be easy to head into direct from either underdrive or the overdrive and shoot right through direct into the opposite neutral.
There were a couple other brands of similar transmissions that used three-speed progressive shift, however, their names escape me at the moment. Moore and Universal, along with several others, also built two-speed units which may have been either under or overdrive along with direct.
Mostly all of these transmissions (with the exception of Planitor) are unique with few if any parts in common with anything else.
Robert S O, Is yours in a car? Or out and loose? If in a car and running, Try it out (carefully!). If out and loose, I would recommend taking it apart carefully and checking all the bearings and gears before going to any effort to fit it into a car. They can be really good to have. However, I have seen more than a few that were total junk.
Drive carefully, and enjoy, W2
I have just installed one in my TT, was really pleased when I took it apart. Looked very good inside, truck is still not on the road yet though. Hopefully this year :-)
Wayne, I bought a 26-7 two door a while back. The body had been changed in the past. The firewall has been set back for a bigger motor I think. This rear end came with it. I have all the linkage as the running gear was complete. I have also picked up a 27 coupe. It has a ruxtell with rockys. The coupe has sat for over 35 years and is testing me. I think Iam going to win and should be able to fire the motor in a few days. Stuck pistons and such. I have pulled the pistons for cleaning, honed the block a tad. Did a valve job so its on its way back together. I would like to use both the tranny and the ruxtell. So thanks for the info on this tranny. I will go thru it after I get the motor running. I have gear machines so I can make replacment parts if needed. Thanks for everyones help, Scott
