Solution

1. Preparation

Gather tools and parts.
Ensure the vehicle is on a flat surface and secure with wheel chocks.
Disconnect the battery to avoid electrical shorts.

2. Fluid Change

Sub-steps:
1. Raise the vehicle using a jack and secure it with jack stands.
2. Remove the transmission pan bolts using a socket set.
3. Carefully lower the pan to drain old fluid into a catch pan.
4. Replace the transmission filter (if applicable).
5. Clean the transmission pan and magnet, inspecting for metal shavings.
6. Reinstall the pan with a new gasket and torque bolts to manufacturer's specifications (typically 10-12 ft-lbs).

3. Replace or Adjust Components

Sub-steps:
1. If the TPS is faulty, disconnect the wiring harness and remove the sensor.
2. Install the new TPS and reattach the wiring harness.
3. For a faulty transmission range sensor, follow the same procedure as above.
4. Ensure the sensor alignment is correct according to the service manual.

4. Reconnect Battery and Test Drive

Sub-steps:
1. Reconnect the battery terminals.
2. Start the vehicle and allow it to warm up.
3. Test drive the vehicle to verify that the transmission shifts smoothly without jerking.
