Solution

1. Preparation

Ensure the vehicle is parked on a level surface and the engine is off.
Gather necessary tools and parts.

2. Check Transmission Fluid

Tools Required: Dipstick, funnel.
Remove the transmission dipstick and wipe it clean.
Reinsert the dipstick and remove it again to check the fluid level.
If low, add the correct type of transmission fluid as specified in the owner’s manual.

3. Replace Transmission Fluid and Filter

Tools Required: Socket set, transmission fluid pump, drain pan.
Position a drain pan under the transmission pan.
Remove the transmission pan bolts and carefully lower the pan to drain the fluid.
Replace the transmission filter according to the manufacturer’s specifications.
Reinstall the pan using a new gasket and torque the bolts to the specified value.

4. Test and Replace Range Sensor

Tools Required: Multimeter.
Disconnect the range sensor electrical connector.
Use a multimeter to check the sensor's resistance and compare it with the specifications.
If faulty, replace the range sensor and reconnect the electrical connector.

5. Inspect and Replace Throttle Position Sensor (if necessary)

Tools Required: Socket set, multimeter.
Locate the throttle position sensor and disconnect the electrical connector.
Use a multimeter to check the voltage output while moving the throttle.
If the sensor is not functioning properly, replace it.

6. Conduct a Test Drive

Once repairs are completed, start the engine and let it warm up.
Shift through all gears to ensure smooth operation and check for any delays.
