TT Aux Tranny?
I've been asked to help a non-hobbyist dispose of some T & TT stuff they inherited. So far I've only seen a few photos but I will be paying a visit sometime in the next month to look it over. The collection includes three C-cabs (just the cabs) and a pile of parts, but one item caught my attention. It appears to be an auxiliary transmission on a TT rear end. I can't quite make out the name on it but it looks like maybe "Rocky Mountain." Can anybody tell me what I'm looking at and whether it would be of value to anyone?

There were several variations of that - 2 speed & 3 speed - Seattle Transmission and or Tractor Train Co. was another.

In the photo it (sort of) clearly says 'Rocky Mountain'
When in trouble, do not fear, blame the second engineer !

Re: TT Aux Tranny?
Yeah. Thats a Rocky Mountain Six Speed. The driveshaft and torque tube-at the least- should be included with the sale. They’re pretty popular if in good internal condition.

Tim,… if those C Cabs were in the “Thumb of Texas”, I’d be highly interested…
