2. Transmission solenoid - Wikipedia

   en.wikipedia.org/wiki/Transmission_solenoid

   A transmission solenoid or cylinoid is an electro-hydraulic valve that controls fluid flow into and throughout an automatic transmission. Solenoids can be normally open or normally closed. They operate via a voltage or current supplied by the transmission computer or controller. Transmission solenoids are usually installed in a transmission ...

3. Variable force solenoid - Wikipedia

   en.wikipedia.org/wiki/Variable_force_solenoid

   A variable force solenoid (VFS) is an electro-hydraulic device that controls pressure proportionally or inversely proportionally to a signal (voltage or current) obtained from the on-board controller of a powertrain. A low flow VFS is used as a signal level devices for transmission line pressure control or application of clutches.

4. 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.

5. Teletouch - Wikipedia

   Pushing a button on the shift control preselected the chosen gear. The electrical circuit was closed only after the driver fully depressed the clutch pedal. This energized the appropriate transmission mounted solenoids necessary for returning the transmission to neutral and then completing engagement of the preselected gear.

6. GM 4L60-E transmission - Wikipedia

   en.wikipedia.org/wiki/GM_4L60-E_transmission

   It weighs 133 pounds without transmission fluid. [1] The 4L60E family of transmissions use 2 shift solenoids, initially called Shift Solenoid A & Shift Solenoid B, later changed to comply with OBD II (On Board Diagnostics revision 2) regulations to 1-2 Shift Solenoid & 2-3 Shift solenoid.

7. Automatic transmission - Wikipedia

   en.wikipedia.org/wiki/Automatic_transmission

   These solenoids are computer-controlled, with the gear selection decided by a dedicated transmission control unit (TCU) or sometimes this function is integrated into the engine control unit (ECU). Modern designs have replaced the centrifugal governor with an electronic speed sensor that is used as an input to the TCU or ECU.

8. 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 ...

9. Chrysler RFE transmission - Wikipedia

   en.wikipedia.org/wiki/Chrysler_RFE_transmission

   The TCM uses data from various transmission and engine sensors to control transmission shifting. The TCM operates the solenoid pack to change hydraulic flow through the valve body to various clutches in the transmission. The solenoid pack is mounted directly to the valve body; its connector protrudes from a hole on the left side of the ...
