  2. Transmission control unit - Wikipedia

    en.wikipedia.org/wiki/Transmission_Control_Unit

    Known as an input speed sensor (ISS). This sensor sends a varying frequency signal to the TCU to determine the current rotational speed of the input shaft or torque converter. The TCU uses the input shaft speed to determine slippage across the torque converter and potentially to determine the rate of slippage across the bands and clutches. This ...

    If the speed sensor detects lock up at any individual wheel, the control module pulses the valve for both wheels on that end of the car. 5) One-channel, one-sensor ABS This system is commonly found on pickup trucks, SUVs, and vans with rear-wheel ABS. It has one valve, which controls both rear wheels, and a one-speed sensor, located in the rear ...

    en.wikipedia.org/wiki/Torque_converter

    This is a feature beyond what a simple fluid coupling provides, which can match rotational speed but does not multiply torque. Fluid-coupling–based torque converters also typically include a lock-up function to rigidly couple input and output and avoid the efficiency losses associated with transmitting torque by fluid flow when operating ...

    en.wikipedia.org/wiki/Motronic

    Motronic is the trade name given to a range of digital engine control units developed by Robert Bosch GmbH (commonly known as Bosch) which combined control of fuel injection and ignition in a single unit. By controlling both major systems in a single unit, many aspects of the engine's characteristics (such as power, fuel economy, drivability ...
