The automatic transmission now receives control from smart modules that are produced by automakers globally. The sensors inside the module are an upgrade to the classic governor units found in hydraulic gearboxes. All vehicles built after 1990 have one or more modules controlling different aspects of speed and shifting. LCP provides access to find and buy used transmission control modules from the largest junk yards in North America.

Computer programming is the main source of knowledge inside of the TCM units now produced for motor vehicles. Along with a series of switches, the computer provides a series of programmed routines to the clutch mechanism and speed control sensor. The use of smart transmission controls is popular although DIY programming is hard to grasp. Many dealerships provide re-programming of TCM modules, but this does come with a higher than standard price tag.
Automobiles that are OBD-II compliant can be tested for proper functionality. The most common error code for a control module is known as the P0700. This is the first sign that an error has been detected. When a person tests a module, an indicator lamp could be lit or slipping might be noticeable during vehicle operation. Since the ECU works with the TCM, each module requires testing prior to making a determination that a problem exists.

Automobiles will usually not start in park when a TCM issue is detected. Some automakers have limp or limp home mode that might interfere with the normal operation of a working module.
