Sub-step 3: If fluid is dirty or burnt, drain the fluid from the transmission pan and replace with new fluid.
Tools Required: Socket set, transmission funnel, fluid pump (if needed).

3. Inspect and Adjust Transmission Linkage

Sub-step 1: Remove any covers obstructing access to the transmission linkage.
Sub-step 2: Visually inspect the linkage for damage or misalignment.
Sub-step 3: Adjust the linkage if necessary to ensure proper alignment with the transmission.
Tools Required: Wrench set, screwdrivers.

4. Replace Faulty Components

If the transmission fluid is fine but the issue persists, check for faulty components identified during diagnostic steps (e.g., brake pedal switch, transmission control module).
Sub-step 1: Remove the faulty component following manufacturer service guidelines.
Sub-step 2: Install the new component, ensuring all connections are secure.
Tools Required: Specific tools as required for the component being replaced.
