Summary: The turbine shaft drives the front planetary ring gear. The K1 clutch, which is<br />
connected to the front planetary carrier, is on. This forces the front planetary assembly to<br />
rotate at a 1:1 ratio. The F1 freewheels as a result of the sun gear (which is connected to the<br />
K1 clutch) rotating with the complete front planetary assembly. The front planetary ring gear<br />
is linked to the rear planetary ring gear, (thru the rotating front planetary carrier). The K2<br />
clutch, which is connected to the rear carrier, is turned on and forces the rear planetary<br />
assembly to rotate at a 1:1 ratio. The B2 brake is turned off and the K3 clutch , which is<br />
connected to the center planetary's sun gear, is turned on. This forces the center planetary<br />
assembly to rotate at a 1:1 ratio.<br />
