I wonder how things might have gone if Ford had perfected a three speed planetary. Cadillac listed one for their 30 and 40 hp models in 1906. I've never seen one, and am curious how the controls worked?
Rob : Ford used the planetary gear box in there Tractors . Ford [SELECTO SPEED ]It was not a big success . Don't asked how I know that !!
I thought the inventor/technician who built the Ford select-o-matic also built the John Deere power shift that became an immediate success in the mid 60s?
The Cadillac transmission seems like a continuation of the 2 speed transmission, and seems like a good concept. This is one of the few 40 hp and higher power cars I've found that used the planetary transmission along with Ford (Model K).
I think I recall a thread that mentioned Ford looked a a three speed planetary in the twenties for the T or it's successor?
The ol' brass picup has a 3 speed planetary: stock tranny plus BorgWarner planetary overdrive.
There was one patented for the T in the mid 20's by some guy. I looked into the idea of making one. Maybe yes maybe no
I never knew Cadillac built a four that early, wonder if any survive? I did see a three speed planetary on this forum a few years ago, but the thread just kinda died, alot of time was spent by someone on this idea.
It was done by a guy named Craig Whipple, amazing design, back in 2009, google search model t forum three speed transmission
Craig's version was not a planetary. It was basically a motorcycle transmission. It was not nearly strong enough to take the torque of a T engine
