All of the Model T accessory gearboxes (Warford, Chicago, Muncie, Jumbo, etc) are most certainly "shift on the fly" transmissions. You should never have to come to a complete stop to shift up or down. I do agree that any car or truck with one of these Auxiliary Overdrive gearboxes SHOULD have Rocky-Mountain brakes and a foot throttle for safety and ease of use!
I have a Chicago Mark-E in my '26 roadster and absolutely love it! They do take some "practice" and "getting used to"....but once you get it, they shift nice and smooth. The are great for making a T drivable...giving 6 total forward speeds and 3 in reverse. I will usually start off from a stop in Underdrive, mash down the low pedal, shifter in to high (on the planetary trans), then wind her out in high, take my foot off the gas as I pull the Chicago into neutral (pause here just for a sec) then pull the lever into direct with no grinding...truly a beautiful thing
Down shifting is a little tricky, but still easy to master. I let the car slow down a bit by taking my foot off the gas, push her into neutral, goose the throttle a bit (pause for just sec) then go for the lower gear.
The key is: if it won't go in, DON'T FORCE IT! ..Don't try to jam it in gear, that is how you break gearboxes. Just a little bit of hand pressure is all you need....if the gears are ready to mesh, they will
The Warford transmissions had a 1st gear (underdrive) ratio of 1.37:1, 2nd (Direct) was 1:1 and 3rd (overdrive) was 1:1.363.
