I have a Caterpillar C15 Accert 475hp set at 550hp... I have a medium duty transmission EatonFuller RTOC 18909A and I am asking if this tranny is the best match up for my engine?

My name is ***** ***** I will assist you.
As long as it is the 1850 torque rating and not the 1650, you are good. The transmission tag will identify that.
Also, I would convert it to the 13 speed for better fuel mileage instead of the 9. You'll get a better resale value on it. Also, this transmission uses two clutches. Make sure you get the iron one and not the aluminum. It will wear way faster with that HP from the engine.
