The transmission shown has a modified full-manual valvebody. As such, the throttle pressure/kick down lever-ordinarily stacked atop the shift lever-is absent on this example.

To get a better understanding of transmissions—we'll leave clutches and torque converters for a future issue—we'll delve into the internal workings of these components.

Modern torque converters use an internal lockup clutch that mechanically connects the engine to the transmission under high-speed low-load conditions to increase efficiency.

A torque converter sits where a clutch normally would, and they have essentially been unchanged since the mid 60’s. Your engine forces transmission oil against fan blades that slip when the car ...

Whether it’s a fully automatic transmission (AT), which uses a torque converter, or automated manual transmission (AMT), which internally operates like a manual but shifts with computer ...
