I bought my brother a Planet jr transmission for a model T. Does anyone know anything about such a transmission. I tried posting a picture but get a message saying file too large.

Is it by chance a Jumbo Planator? See the thread below:

I have a Jumbo Planetor in my '27 touring. Low is great for parades and low /high is great for climbing hills. Shifting quietly is very difficult but it can be done. If the spring is weak they tend to jump out of gear but after going through my spring pile I found one that worked perfectly. I like the unit and don't understand why they apparently did not sell all that well. I originally had it on my '14 but when I moved to Florida there was no reason to use it as there are no hills so I swapped it out for my '27 that I keep in the mountains. The whole swap from one car to the other took less than 3 hours.

Let's hope it didn't stand like that for decades with rain filling it up from the u-joint..

The other thing about the Jumbo Planetor is that it gives you a free neutral and it can get stuck in neutral so auxiliary brakes are a must if you plan to use it.

Interesting to see truss rods on a 26/27 rear end - they were more common before 1915 when Model T rear ends were much weaker.

Truss rods probably installed because of the additional mass of the Planitor. However truss rods are not seen when Langbein, Rocky Mountain, Universal drive-line transmissions are mounted...also Ruckstell.

Stan and I rebuilt mine in 2013. Fairly straight forward. We posted some pictures but I was not able to find the thread.
