Disconnect the negative battery terminal to ensure safety.

2. Check and Replace Transmission Fluid

Tools Required: Transmission fluid pump, funnel, socket set, torque wrench.
Drain the old transmission fluid using a fluid pump.
Replace the transmission filter if necessary.
Refill with the manufacturer-recommended transmission fluid type (check the owner’s manual for specifications).
Torque the transmission pan bolts to the manufacturer’s specifications.

3. Inspect and Replace Transmission Solenoids

Tools Required: Socket set, screwdriver, multimeter.
Remove the transmission pan to access the solenoids.
Disconnect the electrical connectors from the solenoids.
Use a multimeter to test resistance and functionality of each solenoid; replace if faulty.
Reassemble the transmission pan and refill with fluid.

4. Adjust or Replace Transmission Linkage
