Reducing resistor automatic transmission Nissan March
The automatic transmission pull-down resistor is designed to regulate the voltage supplied to the automatic transmission solenoids to ensure smooth gear shifts. It is an important component of the automatic transmission control system.
Location
The automatic transmission reduction resistor is usually located in the engine compartment, next to the automatic transmission control unit. On a Nissan March it is usually located on the left side of the cylinders, next to the battery.
Signs of malfunction
A faulty automatic transmission reduction resistor can cause the following symptoms:
*Hard gear shifts
* Gear slippage
* Delay when shifting gears
* Gear changes too early or late
* Error codes on the diagnostic scanner
Replacing the automatic transmission reduction resistor
To replace the automatic transmission step-down resistor you will need the following tools:
* Wrench set
* Socket wrench
* Screwdriver
* New automatic transmission reduction resistor
Replacement steps:
1. Disconnect the negative terminal of the battery.
2. Find the automatic transmission reduction resistor.
3. Disconnect all electrical wires going to the resistor.
4. Remove the bolts securing the resistor to the car.
5. Remove the old resistor and install the new one.
6. Tighten the bolts.
7. Connect the electrical wires to the new resistor.
8. Connect the negative terminal of the battery.
Note: After replacing the automatic transmission pull-down resistor, it may be necessary to reset the transmission adaptations using a diagnostic scanner. This will ensure that the transmission shifts correctly once the new part is installed.
Part number
The part number for the automatic transmission pull-down resistor for Nissan March may vary depending on the year of manufacture and model of the vehicle. Consult your vehicle’s repair manual or local Nissan dealer for the correct part number.
