Ever wonder how your transmission knows to shift gears? Why is it that when you stop, the engine doesn’t die? We’re here to show you how cars work. We recently looked at manual transmissions.

The automatic transmission is made up of three parts: the torque converter, the planetary gears, and the brake bands and clutches. As the engine runs, it spins the torque converter's impeller ...

This turbine moves only when transmission fluid is thrown off by centrifugal force from a similar-appearing piece called the impeller assembly. As the impeller spins with the engine rpm, steel ...

A torque converter has three main parts that make it work: the impeller, which is attached to the engine, the turbine, which is connected to the transmission, and the stationary stator in the middle.

ATI shows us a new torque converter impeller shell, which is actually tied to the transmission's front pump. The pump's drive hub hasn't been installed yet. These fins move fluid through the ...

The fact is, most transmission failures in mildly modified diesel trucks can be linked to the torque converter. Additional power made by the addition of a tuner can exceed the handling limits of ...
