Still going through my TT.
I have two shifters. One next to the parking brake. The other located in the center of the cab.
The one next to the parking brake controls the shift lock assembly. The center stick connects to a drive shaft box (?).
Could use some clarification from the experts as to the function of each.
Many thanks in advance.

Re: Ruckstell question
Ruckstell shifts as follows: lever back is in Ruckstell - lever forward is Ford Direct. Is the "gearbox" mounted to the rear axle or up front near the
engine ? Pull the floorboards so we can see what you have.

Re: Ruckstell question
Rocky Mtn. "6" speed is a 3 speed with under, direct & over. I've not shifted that transmission as I have a 3 speed Warford with a conventional (not really) shift pattern - yours is "inline" so I suggest jacking her up and go through the gears.

Re: Ruckstell question
Goldmine, a TT with an auxiliary gear box!.
The Ruckstell gives an under drive speed or standard 'Direct' or 'Ford' speed. The Ruckstell gear makes the TT go slower - more power uphill under load.
The Rocky Mountain auxiliary gearbox gives you a combination of higher gearing and a lower gear too. With this you will be able to crawl along (good for parades - or picking up the hay bales https://www.youtube.com/watch?v=BX-EIAYe7E4) using Ruckstell gear and RM low, or you may be able to 'zip' along at a better cruise speed (Ruckstell 'Direct'/'Ford' and RM high).
The TT does not really like going too fast for long periods, but I find 30mph is fine with bursts up to 35 mph (I did 45mph once - earned a few grey hairs that time).
With some practise you may be able to emulate a 'big rig' and change up through the gears in bursts as instead of the standard 2 speeds you now have 8 (assuming the '2nd' RM gear is a 'Direct').
Cheers

Re: Ruckstell question
Don't bet on the Rocky Mountain being a "six" speed! Every Rocky Mountain or Universal in-line shifting rear-mounted three/six auxiliary transmission that I saw or had for a model T or TT had a "bulge" in the center casing. This one has enlargements front and rear which is how the two speed transmissions usually had.
Basically, all the two speed versions had one position was direct drive, the other would be either overdrive OR underdrive. Whether the larger enlargement is on the front or rear of the center case can tell you whether it is an underdrive or an overdrive (I will have to think about this for a minute to remember which is which?). There is also a neutral between the two gear choices.
The "six" speed versions had underdrive, direct, and overdrive, in a progressive shift pattern (sometimes referred to as "UDO"). Those also have not one, but TWO neutrals to get stuck in! That is to some extent a joke, albeit a very important one as a reminder that getting stuck in neutral is a very real possibility, and adequate brakes for such an eventuality are a must. (TT lined parking brakes are adequate IF they are in proper good order and properly adjusted!) Another reality of these type transmissions, is that they are of a constant mesh design, and generally very easy to shift the gears! Getting stuck in neutral with them is somewhat rare.
I have had a few model Ts with these type transmissions. The only problem I ever really had shifting them was a few times hitting a bump in the road while shifting into direct from either underdrive or overdrive, and because of the bump slipping straight though direct into the other extreme. Which of course was improper for the speed I was travelling and therefore requiring me to fumble my way back into direct! Got it?
It should be pointed out that the "six speed" nomenclature is marketing's idea that the auxiliary's three speeds times the Ford's planetary high and low equaled "six" speeds. (Don't argue with Madison Avenue.) (The old saying, "Who is the bigger fool? The known fool? Or the fool that argues with the known fool?)
And sorry to tell you. After thinking about it, and focusing on the photo to determine front and back? I am pretty sure you have another underdrive there.
Some of those transmissions had "under" or "over" stamped into the center case somewhere. The center case itself could be mounted in the middle in either direction. However the input and output gears were machined differently. The Universal brass casing I had in my TT many years ago had "overdrive" stamped onto a special embossment. It was really nice. My TT could cruise for hours at 40mph in that Universal (brand name!) overdrive! Of course it was a bit slower in the hills when I had to shift into direct.
