Solution

1. Preparation

Tools Required: OBD-II scanner, socket set, fluid catch pan, transmission fluid, funnel.
Ensure the vehicle is parked on a flat surface and the engine is off.
Disconnect the battery to avoid electrical shorts.

2. Check and Replace Transmission Fluid

Sub-steps:
1. Locate the transmission dipstick and remove it.
2. Use a funnel to add new transmission fluid if low.
3. If fluid is burnt or contaminated, drain the transmission fluid using a catch pan.
4. Replace with the manufacturer-recommended transmission fluid type.

3. Replace Transmission Filter

Sub-steps:
1. Remove the transmission pan bolts using a socket set.
2. Carefully lower the pan and allow fluid to drain.
3. Remove the old filter and install a new transmission filter.
4. Clean the pan and replace the gasket before reinstalling the pan.

4. Inspect and Replace Throttle Position Sensor (if faulty)

Sub-steps:
1. Locate the throttle position sensor on the throttle body.
2. Disconnect the electrical connector.
3. Remove the screws securing the sensor and replace it with a new one.
4. Reconnect the electrical connector.

5. Check Transmission Control Module

Sub-steps:
1. Access the transmission control module (usually located under the dashboard).
2. Inspect for corrosion or damage to the connector and wiring.
3. Replace the module if necessary, following manufacturer specifications.
