Tools Required: Socket set, fluid pump, transmission fluid.
Sub-steps:
1. Remove the transmission fill plug using a socket.
2. Insert a fluid pump into the transmission fluid fill port.
3. Extract old fluid and replace it with new manufacturer-recommended transmission fluid.
4. Reinstall the fill plug and torque to manufacturer specifications.

3. Replace Transmission Filter

Tools Required: Socket set, screwdriver, transmission filter kit.
Sub-steps:
1. Remove the transmission pan by unscrewing the bolts with a socket.
2. Carefully detach the pan and drain any remaining fluid.
3. Remove the old transmission filter from its mounting.
4. Install the new filter, ensuring it is seated properly.
5. Clean the transmission pan and reinstall it, torquing the bolts to the specified value.

4. Test Transmission Solenoids

Tools Required: Multimeter.
Sub-steps:
1. Disconnect the wiring harness from the transmission solenoids.
2. Use a multimeter to check the resistance of each solenoid.
3. Replace any solenoids that do not meet manufacturer specifications.

5. Reconnect Everything and Check for Errors
