Solution

1. Preparation

Gather tools and materials.
Ensure the vehicle is parked on a level surface and the engine is off.
Disconnect the battery to prevent any electrical issues during repairs.

2. Check and Replace Transmission Fluid

Remove the transmission dipstick and check the fluid level.
- Tools Required: Transmission dipstick, funnel.
If fluid is low, add the manufacturer-recommended transmission fluid until the correct level is reached.
If fluid is dirty or burnt, proceed to change the fluid.
- Sub-steps:
  1. Remove the transmission pan bolts and carefully lower the pan.
  2. Clean the pan and replace the filter.
  3. Reinstall the pan, ensuring to torque the bolts to manufacturer specifications.
  4. Refill the transmission with the appropriate fluid.

3. Inspect and Adjust Transmission Linkage

Visually inspect the linkage for any signs of damage or misalignment.
If necessary, adjust the linkage according to the service manual specifications.
Tools Required: Wrench set, socket set.

4. Test and Replace Transmission Solenoids

Remove the transmission solenoids and test them with a multimeter.
- Tools Required: Multimeter.
If any solenoids are faulty, replace them with new units.
Reassemble the transmission components after testing.

5. Reassemble and Reconnect Battery

Once all repairs are made, ensure all components are securely attached.
Reconnect the battery and clear any error codes using an OBD-II scanner.
