Solution

1. Preparation

Ensure the vehicle is on a level surface and securely lifted with jack stands.
Disconnect the battery to prevent electrical shorts.

2. Inspect and Replace Transmission Fluid

Check Fluid Level:
- Remove the transmission dipstick, wipe clean, reinsert, and check the fluid level.
Drain Old Fluid:
- Position a drain pan under the transmission pan.
- Remove the transmission pan bolts and carefully lower the pan to drain the fluid.
Replace Fluid:
- Reinstall the transmission pan with a new gasket.
- Fill the transmission with manufacturer-recommended fluid through the dipstick tube.

3. Replace Transmission Filter

Remove Transmission Pan:
- Follow the steps in the previous section to remove the pan, if not already done.
Replace Filter:
- Remove the old filter and install the new filter, ensuring it is seated properly.
Reinstall Pan:
- Reattach the transmission pan and torque the bolts to manufacturer specifications (usually around 10-12 ft-lbs).

4. Test Transmission Solenoids

Access Solenoids:
- If faulty, remove the transmission valve body to access the solenoids.
Test:
- Use a multimeter to check the resistance of each solenoid against specifications. Replace any that are out of range.

5. Reassemble and Refill

Reconnect the battery.
Start the engine and allow it to reach operating temperature.
Check fluid levels again and top off if necessary.
