What is the function of the transducer? Stuck in "Limp In Mode"
A transducer is a sensor that does not need to make physical contact with what is is trying to sense. It can be used to detect the presence or position of something; on boats they are used to sense the distance to the bottom to determine the depth of the water.
These devices are typically employed to provide feedback - or "prove" that a command has completed or component is in the right place ie: A command to shift from position "A" to position "B" will be halted when the transducer at position "B" detects the presence of the shifter.
If the transducer is unable to detect the shifter at "B" or falsely detects that the shifter is always at "B" - it can cause problems. The device (computer or controller) that interprets the transducer output has no way of knowing if the shift has completed or not and can decide do something to limit damage to the motor, transmission, etc.
