Solution

1. Preparation

Gather tools and materials.
Ensure the vehicle is on a flat surface and securely lifted using jack stands.
Disconnect the battery to avoid electrical shorts.

2. Check and Replace Transmission Fluid

Sub-steps:
1. Locate the transmission dipstick and pull it out.
2. Wipe the dipstick clean and reinsert it to check the fluid level.
3. If low, remove the transmission pan (ensure to collect any fluid in a drain pan).
4. Replace the old fluid with new transmission fluid recommended by the manufacturer (check owner's manual for specifications).
5. Reinstall the transmission pan with a new gasket and torque the bolts to the specified value.

3. Replace Transmission Filter

Sub-steps:
1. With the transmission pan off, locate and remove the old transmission filter.
2. Install the new filter, ensuring it is seated properly.
3. Reattach the transmission pan.

4. Inspect and Replace Solenoids (if needed)

Sub-steps:
1. Locate the transmission solenoid pack.
2. Disconnect the electrical connector and remove the solenoid assembly.
3. Install the new solenoids and reconnect the electrical connector.

5. Refill and Test

Sub-steps:
1. Refill the transmission with new fluid to the proper level.
2. Start the engine and cycle through the gears while checking for leaks.
3. Test drive the vehicle to ensure proper shifting and operation.
