Solution

1. Preparation

Gather tools and safety equipment.
Ensure the vehicle is parked on a level surface and the engine is cool.
Disconnect the battery to prevent electrical shorts.

2. Check and Top Off Transmission Fluid

Locate the transmission dipstick or fill plug.
Remove the dipstick, wipe clean, and reinsert to check fluid level.
If low, add the manufacturer-specified transmission fluid through the dipstick tube or fill plug until it reaches the proper level.

3. Replace Transmission Filter (if applicable)

Raise the vehicle securely on jack stands.
Place a drain pan under the transmission pan.
Remove the transmission pan bolts using a socket set and carefully lower the pan.
Remove the old filter and install the new filter.
Clean the pan and replace the gasket before reinstalling the pan.

4. Test Transmission Solenoids

Locate the solenoid pack on the transmission.
Disconnect the electrical connectors and remove the solenoid pack.
Test each solenoid with a multimeter according to the manufacturer's specifications.
Replace any solenoids that do not meet specifications.

5. Reassemble and Refill Fluid

Reinstall the transmission pan and torque the bolts to the manufacturer’s specifications.
Reconnect the battery.
Start the engine and let it run for a few minutes, then check the transmission fluid level again and add fluid as necessary.
