Number of teeth in planetary gear sets?

07-22-2018, 08:48 AM
I know that TH350 automatic transmission has gear ratios of 2:5, 1:5, and 1:1. I tried to search the Internet to find the number of teeth in planetary gear sets but I couldn't find anything. Does anyone know the number of teeth in planetary gear set? I wish to create a working 3D model of the transmission.

I found images of sun gear and ring gear on the Internet, counted the teeth on them, and found out that the sun gear has 36 teeth, ring gear has 72 teeth, and planet gears have 18 teeth. Are they correct?
