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.
The service manual explains that Autostick signaling is multiplexed on a single wire. The transmission control module outputs a 5v signal to the handle and monitors it for voltage drop The voltage ranges 0.3-1.6,1.6-2.8, 2.8-3.8, and 3.8-4.8 representing down, up, overdrive lockout, and all open respectively.
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 ...
An electronic control unit (ECU), also known as an electronic control module (ECM), is an embedded system in automotive electronics that controls one or more of the electrical systems or subsystems in a car or other motor vehicle.
"Under this final rule, each public utility (or its agent) that owns, controls, or operates facilities used for the transmission of electric energy in interstate commerce will be required to create or participate in an OASIS that will provide open access transmission customers and potential open access transmission customers with information ...
The Ultradrive is an automatic transmission manufactured by Chrysler beginning in the 1989 model year.. Initially produced in a single four-speed variant paired with the Mitsubishi (6G72) 3.0-liter engine in vehicles with transverse engines, application was expanded to the Chrysler 3.3- and 3.8-liter V6 engines in 1990 model year Dodge Caravan/Grand Caravan, Plymouth Voyager/Grand Voyager ...

It is nicknamed "The City on the Circle", in reference to Circle Drive, the center of the Sebring Downtown Historic District. [7] [8] It is the principal city of the Sebring, Florida Metropolitan Statistical Area. [9]
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.
