Automatic transmission switching resistor (TRS) in Nissan Tiida
The Transmission Shift Resistor (TRS) is an electrical component that is used to regulate the voltage supplied to the transmission shift solenoids. This helps ensure smooth gear changes for comfortable and efficient driving.
Location:
*Located in the engine compartment, usually near the transmission.
* Bolted to the gearbox housing.
Functions:
*Adjusts the voltage supplied to the shift solenoids for smooth shifting.
* Helps prevent shifting jerks and delays.
* Optimizes automatic transmission performance in various driving conditions.
Symptoms of malfunction:
*Hard or delayed gear shifting
*Slippage or shock when shifting gears
*Transmission errors or Check Engine light
* Increased fuel consumption
Diagnostics:
* Diagnostic scanner to read TRS related trouble codes.
* Multimeter to check the voltage at the TRS and its terminals.
* Physically inspect the TRS for damage or corrosion.
Replacement:
* Disconnect the negative battery cable.
* Find the TRS and unscrew it with a wrench.
* Disconnect the electrical connector.
* Install the new TRS in place.
* Tighten the bolt and connect the electrical connector.
* Connect the negative battery cable.
Notes:
*Only use original or high quality TRS designed for Nissan Tiida.
*Refer to your repair manual for specific replacement instructions for your vehicle.
*After replacing the TRS, it may be necessary to reset the transmission adaptation settings using the diagnostic scan tool.
