Solution

1. Preparation

Gather tools and parts necessary for the repair.
Ensure the vehicle is on a level surface and engage the parking brake.
Disconnect the battery to avoid electrical shorts.

2. Fluid Change

Sub-steps:
1. Drain the Transmission Fluid:
  - Locate the transmission drain plug and remove it using a socket wrench.
  - Allow the fluid to drain completely into a suitable container.
2. Replace the Filter:
  - Remove the transmission pan by loosening the bolts with a socket set.
  - Carefully detach the pan and replace the old filter with a new one.
3. Clean the Pan:
  - Clean the transmission pan and magnet to remove debris before reinstallation.
4. Reinstall the Pan:
  - Place a new gasket on the transmission pan and secure it back with bolts to the specified torque (check manufacturer specs).
5. Refill with New Fluid:
  - Use the manufacturer-recommended transmission fluid type and fill through the dipstick tube until the proper level is reached.

3. Solenoid Replacement (if necessary)

Sub-steps:
1. Access the Transmission Solenoids:
  - Remove the transmission pan again if already removed.
2. Disconnect the Solenoids:
  - Unplug the electrical connectors from the solenoids.
3. Remove and Replace:
  - Unscrew the solenoids using a socket wrench and replace them with new ones.
4. Reassemble:
  - Reinstall the transmission pan and refill the fluid as described above.

4. TCM Reset

Sub-steps:
1. Reconnect the Battery:
  - Reconnect the battery terminals securely.
2. Perform a TCM Reset:
  - Use a compatible scan tool to clear any transmission fault codes and reset the TCM.
