Solution

1. Preparation

Gather necessary tools and parts.
Disconnect the vehicle battery to ensure safety during electrical work.

2. Check and Replace Transmission Fluid

Locate the transmission dipstick and remove it.
Inspect fluid level; if low, add the appropriate transmission fluid as per the owner’s manual.
If the fluid is burnt or dirty, drain the old fluid using a transmission drain pan.
Replace the transmission fluid filter if applicable.
Refill the transmission with the correct type and amount of new fluid.

3. Inspect and Replace Transmission Speed Sensors

Identify the location of the speed sensors (typically on the transmission case).
Disconnect the wiring harness from the sensors.
Remove the sensors using the appropriate socket or wrench.
Install new speed sensors, ensuring they are correctly seated and connected.
Reconnect the battery and clear any stored error codes.

4. Check and Replace Throttle Position Sensor

Locate the throttle position sensor (typically near the throttle body).
Disconnect the electrical connector from the sensor.
Remove the screws or bolts securing the sensor and take it out.
Install the new throttle position sensor and reconnect the wiring harness.
Reset the vehicle's ECU if necessary to recalibrate the new sensor.
