2. Transmission control unit - Wikipedia

   en.wikipedia.org/wiki/Transmission_Control_Unit

   A transmission control unit (TCU), also known as a transmission control module (TCM), or a gearbox control unit (GCU), is a type of automotive ECU that is used to control electronic automatic transmissions. Similar systems are used in conjunction with various semi-automatic transmissions, purely for clutch automation and actuation.

3. Powertrain control module - Wikipedia

   en.wikipedia.org/wiki/Powertrain_control_module

   A power-train control module, abbreviated PCM, is an automotive component, a control unit, used on motor vehicles. It is generally a combined controller consisting of the engine control unit (ECU) and the transmission control unit (TCU). On some cars, such as many Chryslers, there are multiple computers: the PCM, the TCU, and the Body Control ...

4. Electronic control unit - Wikipedia

   en.wikipedia.org/wiki/Electronic_control_unit

   Modern vehicles have many ECUs, and these can include some or all of the following: engine control module (ECM), powertrain control module (PCM), transmission control module (TCM), brake control module (BCM or EBCM), central control module (CCM), central timing module (CTM), general electronic module (GEM), body control module (BCM), and ...

5. Chrysler RFE transmission - Wikipedia

   en.wikipedia.org/wiki/Chrysler_RFE_transmission

   This design allows the vehicle to be driven (in “limp-in” mode) in the event of an electronic control system failure, or a situation that the Transmission Control Module (TCM) recognizes as potentially damaging to the transmission. On the 68RFE, fourth gear is used for limp-in instead of second and third. All RFE transmissions use Mopar ATF +4.

6. Engine control unit - Wikipedia

   en.wikipedia.org/wiki/Engine_control_unit

   Delco ECU used in General Motors vehicles built in 1996. An engine control unit (ECU), also called an engine control module (ECM), [1] is a device that controls various subsystems of an internal combustion engine.

7. Electronic throttle control - Wikipedia

   en.wikipedia.org/wiki/Electronic_throttle_control

   A typical ETC system consists of three major components: (i) an accelerator pedal module (ideally with two or more independent sensors), (ii) a throttle valve that can be opened and closed by an electric motor (sometimes referred to as an electric or electronic throttle body (ETB)), and (iii) a powertrain or engine control module (PCM or ECM). [4]

8. Throttle position sensor - Wikipedia

   en.wikipedia.org/wiki/Throttle_position_sensor

   A throttle position sensor (TPS) is a sensor used to monitor the throttle body valve position for the ECU of an engine. The sensor is usually located on the butterfly spindle/shaft, so that it can directly monitor the position of the throttle.

9. Crankcase - Wikipedia

   en.wikipedia.org/wiki/Crankcase

   Many two-stroke engines use a crankcase-compression design, where a partial vacuum draws the fuel/air mixture into the engine as the piston moves upwards. Then as the piston travels downward, the inlet port is uncovered and the compressed fuel/air mixture is pushed from the crankcase into the combustion chamber.
