For the Nissan Sunny FB15 automatic transmission, the reduction resistor has the following characteristics:
Number of parts: 31746-9FB0A
Nominal value: 51 ohms
Power: 10 Watt
Accuracy: ±5%
Installation location: Automatic transmission control unit
Function:
A step-down resistor is used to regulate the voltage on the automatic transmission shift solenoids. It converts the input voltage from the transmission control module (TCM) to a voltage compatible with the solenoids.
Typical signs of a bad resistor:
*Hard shifting
* Gear slippage
* Torque converter lockup problems
*DTCs P0755, P0756, P0757, P0758
Note:
*Resistor replacement requires special tools and knowledge.
* It is recommended that you contact a qualified mechanic for repairs.
