Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is on a level surface and securely lifted.
Disconnect the battery to ensure safety.

2. Check and Change Transmission Fluid

Tools Required: Socket set, funnel, transmission fluid pump, drain pan.
Remove the transmission drain plug and allow old fluid to drain into the pan.
Replace the drain plug and torque to manufacturer specifications.
Use a funnel to refill the transmission with the recommended fluid type until the fluid level reaches the correct mark on the dipstick.

3. Inspect and Adjust Transmission Linkage

Tools Required: Wrench set, screwdrivers.
Locate the transmission linkage and inspect for any signs of damage or wear.
If misaligned, adjust the linkage according to the manufacturer's specifications.
Secure all fasteners and ensure proper range of motion.

4. Reconnect Battery and Clear Codes

Reconnect the battery terminals.
Use the OBD-II scanner to clear any transmission-related error codes.

5. Conduct Final Checks

Start the vehicle and allow it to warm up.
Shift through all gears to ensure smooth operation and proper engagement.
Monitor fluid levels again to ensure no leaks are present.
