2. Check and Change Transmission Fluid

Tools Required: Transmission fluid pump, socket set, drain pan.
Remove the transmission drain plug and drain the fluid into a pan.
Inspect the fluid for contaminants or burnt smell.
Replace with manufacturer-recommended transmission fluid and refill to the correct level.

3. Inspect and Adjust Transmission Linkage

Tools Required: Socket set, wrench set.
Locate the transmission linkage under the vehicle.
Check for any loose or frayed connections.
Adjust the linkage to ensure proper engagement with the transmission.

4. Replace Throttle Position Sensor (if faulty)
