Solution

1. Preparation

Tools Required: OBD-II scanner, multimeter, socket set, torque wrench, fluid pump.
Disconnect the negative battery terminal to ensure safety while working on the vehicle.

2. Fluid Change

Drain Old Transmission Fluid
- Place a drain pan under the transmission pan.
- Remove the transmission pan bolts and carefully lower the pan to drain the fluid.
- Clean the pan and magnet inside for metal shavings.
Replace Transmission Filter
- If applicable, remove the old transmission filter.
- Install the new filter, ensuring it is seated correctly.
Install New Gasket
- Place a new gasket on the transmission pan.
- Reattach the pan, tightening the bolts to the manufacturer’s specified torque settings.
Add New Transmission Fluid
- Use the fluid pump to add the manufacturer-recommended transmission fluid through the dipstick tube.
- Check the fluid level with the dipstick, ensuring it is within the correct range.

3. Inspect and Replace Shift Solenoids (if needed)

Remove the Transmission Pan Again (if necessary)
- If shift solenoids are accessed through the transmission pan, repeat the previous pan removal steps.
Test and Replace Solenoids
- Disconnect the electrical connectors and remove the solenoids.
- Test each solenoid with a multimeter; replace any that are out of specification.
Reassemble the Transmission
- Reinstall the pan and ensure it is sealed properly.
