Downshift resistor, automatic transmission (AT) Nissan Cefiro A32
The Reduction Resistor (RLR) is an important component in the transmission control system in Nissan Cefiro A32 vehicles. Here is its location and functions:
Location:
*The downshift resistor is located under the hood, usually near the engine control module (ECM).
* It usually comes in a black plastic case with an electrical connector.
Functions:
* RLR is responsible for reducing the voltage supplied to the downshift solenoid in the automatic transmission.
* This allows downshifts at lower speeds, which improves acceleration and saves fuel.
*When the RLR is faulty, there may be a problem with gear shifting, such as:
* Gear slip
* Premature upshift
*No downshifting
Check and replacement:
*Check the RLR resistance using an ohmmeter. The resistance should be as specified in the service manual.
*If resistance is out of specification, replace RLR.
* To replace the RLR, disconnect the electrical connector and unscrew its fastening.
* Install the new RLR and tighten the fastener.
* Reset the automatic transmission memory to adapt it to the new RLR.
