Solution

1. Preparation

Gather necessary tools and parts. Ensure the vehicle is parked on a level surface.
Disconnect the battery to avoid electrical shorts and ensure safety.
Tools required: Socket set, Torque wrench, OBD-II scanner, Multimeter.

2. Check and Replace Transmission Fluid

Sub-steps:
1. Locate the transmission dipstick and remove it.
2. Using a funnel, add the manufacturer-recommended transmission fluid (e.g., Mercon LV) to the correct level indicated on the dipstick.
3. If the fluid is burnt or contaminated, proceed to drain the old fluid.
  - Drain Procedure:
    - Remove the transmission pan bolts using a socket wrench.
    - Carefully lower the pan to avoid spillage; allow old fluid to drain completely.
    - Clean the pan and magnet, removing any debris.
4. Replace the transmission filter by removing the old filter and installing a new one.
5. Reinstall the transmission pan with a new gasket and torque bolts to specification (typically around 10-15 ft-lbs).

3. Inspect and Replace Transmission Solenoids (if necessary)

Sub-steps:
1. Remove any necessary components to access the transmission solenoids (consult the service manual for specifics).
2. Disconnect the electrical connectors from the solenoids.
3. Use a multimeter to check the resistance of each solenoid; replace any that are out of specification.
4. Install new solenoids by reversing the removal process, ensuring connectors are secure.

4. Reset Transmission Control Module (TCM)

Sub-steps:
1. Reconnect the battery.
2. Use the OBD-II scanner to clear any transmission-related error codes.
3. Perform a TCM reset if necessary, following manufacturer-specific procedures (usually involves disconnecting the battery for a short period).
