Sensors in Allison automatic transmissions
For reliable and uninterrupted operation, for smooth and clear gear shifting in automatic transmissions (automatic transmission) “Allison” (“Allison”) with an electronic control system uses data from sensors. Sensors are used to obtain speed information (“Speed sensors” – sensors installed directly in the automatic transmission), as well as the position of the accelerator pedal (“TPS – throttle position sensor” or “load sensor”). Pressure change sensors are installed in the hydraulic system.
Gas pedal position sensors depending on the model and design of the vehicle, the location of the sensor (“TPS”) has different lengths. This is important when choosing them for replacement.
