Solution

1. Preparation

Tools Required: OBD-II scanner, socket set, torque wrench, transmission fluid pump, multimeter, safety goggles, gloves.
Ensure the vehicle is parked on a level surface, and the engine is turned off.
Disconnect the battery to prevent electrical shorts.

2. Check Transmission Fluid

Remove the transmission dipstick and check the fluid level.
If low, add the appropriate transmission fluid (check owner’s manual for specifications).
If the fluid is discolored or has a burnt smell, proceed to change the fluid.

3. Change Transmission Fluid

Tools Required: Transmission fluid pump, fluid catch pan.
Place a fluid catch pan under the transmission pan.
Remove the transmission pan bolts and carefully lower the pan to drain the old fluid.
Replace the transmission filter if applicable (some models have this feature).
Install a new gasket and reattach the pan, torquing the bolts to the manufacturer’s specifications.
Use a transmission fluid pump to refill the transmission with new fluid through the dipstick tube.

4. Inspect and Test Torque Converter Lock-Up Solenoid

Locate the torque converter lock-up solenoid, usually found on the transmission.
Disconnect the electrical connector and test using a multimeter to check for continuity.
If faulty, replace the solenoid with a new one.

5. Reassemble and Reconnect

Reconnect the battery.
Start the engine and allow it to reach operating temperature.
Check for leaks around the transmission pan and solenoid.
