Sub-steps:
1. Remove the transmission pan to access the filter.
2. Locate and remove the old transmission filter; discard it.
3. Install the new transmission filter, ensuring it is seated properly.
4. Reinstall the transmission pan and torque bolts to the manufacturer's specifications.

4. Test Transmission Solenoids

Sub-steps:
1. Disconnect the wiring harness from the transmission solenoids.
2. Use a multimeter to check the resistance of each solenoid against manufacturer specifications.
  - Replace any solenoids that are outside the acceptable range.
3. Reconnect the wiring harness securely.

5. Reassemble and Reconnect Battery

Sub-steps:
1. Reinstall any components removed during the process.
2. Reconnect the negative battery terminal.
