When you buy by means of hyperlinks on our web-site, we could get paid an affiliate Fee. Right here’s how it really works.

To start with Gear In 1st equipment, the smaller Sunlight equipment is pushed clockwise from the turbine while in the torque converter. The World copyright tries to spin counterclockwise, but is held even now via the a person-way clutch (which only enables rotation inside the clockwise course) as well as ring gear turns the output. The tiny gear has thirty enamel along with the ring gear has seventy two, so the equipment ratio is:
