Transmission Gear Train

[noobokgbp]

Hi all,

This ones confusing me, I'm having trouble understanding how to find the gear train ratio for the following speeds. Hoping someone can help me with a step-by-step explanation.

Thos diagrams are much easier to understand if you color each active gear, clutch, and control line, in a different color. It takes me most of a morning to do a 4 speed Ravigneaux, so I'm afraid you are on your own.

OP
There is planetary gear trains with low and high speed gear trains with reduction gear set.
This would confuse any one. Must be part a ship drive, I am guessing.
I don't believe there is enough information.
For example which is the driver, driven, and stationary in the planetary drive.
I think it would be easier to contact the engineering department of the manufacture.
There is plenty of sources explaining planetary driven and gear ratios.
