Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is parked on a level surface and engage the parking brake.
Disconnect the negative battery terminal to prevent electrical shorts.

2. Check and Replace Transmission Fluid

Tools Required: Transmission fluid pump, funnel, 10mm socket, torque wrench.
Remove the transmission fluid fill plug using a 10mm socket.
Insert the fluid pump into the transmission fill hole and add the specified transmission fluid (consult owner’s manual for type).
Check the transmission fluid level using the dipstick; add more fluid if necessary.
Reinstall the fill plug and torque to manufacturer specifications.

3. Replace Transmission Filter

Tools Required: Socket set, screwdriver, transmission fluid catch pan.
Place the fluid catch pan under the transmission.
Remove the transmission pan bolts using a socket set.
Carefully lower the transmission pan and discard old fluid.
Remove the old filter and install a new filter, ensuring it is seated properly.
Clean the sealing surface of the transmission pan and install a new gasket.
Reinstall the transmission pan and torque the bolts to manufacturer specifications.

4. Inspect and Replace Solenoids (if faulty)

Tools Required: Torque wrench, socket set.
Remove the transmission valve body by unscrewing the bolts.
Disconnect the electrical connectors from the solenoids.
Remove the solenoids and replace with new units.
Reassemble the valve body and ensure all connectors are securely fastened.
