Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is parked on a flat surface and the engine is off.
Disconnect the battery to prevent electrical shock.

2. Check and Replace Transmission Fluid

Tools Required: Socket set, funnel, drain pan
Locate the transmission pan and remove the drain plug to drain the old fluid into the pan.
Inspect the old fluid for metal particles or burning smell; if present, it may indicate internal damage.
Replace the drain plug and refill the transmission with new fluid using a funnel, ensuring to use the manufacturer's specified fluid type.
Torque the drain plug to the manufacturer’s specifications.

3. Inspect and Replace Transmission Range Sensor

Tools Required: Socket set, multimeter
Disconnect the electrical connector from the transmission range sensor.
Use a multimeter to check the resistance according to the service manual specifications.
If the sensor is faulty, remove the mounting bolts and replace it with a new sensor.
Reconnect the electrical connector and check for proper function by shifting through all ranges.

4. Inspect Engine and Transmission Mounts

Tools Required: Jack, jack stands, socket set
Lift the vehicle and secure it with jack stands.
Visually inspect engine and transmission mounts for cracks or signs of wear.
If damaged, remove the mounting bolts and replace them with new mounts, ensuring proper alignment.

5. Test Drive

Reconnect the battery and start the engine.
Take the vehicle for a test drive to ensure that the jerking issue has been resolved.
