Solution

1. Preparation

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

2. Check and Replace Transmission Fluid

Sub-steps:
1. Locate the transmission dipstick and remove it to check fluid level.
2. If low, use a fluid pump to add the appropriate transmission fluid as specified in the owner’s manual.
3. If the fluid appears burnt or dirty, proceed to drain the transmission fluid.
4. Place a drain pan under the transmission pan and remove the transmission pan bolts using a socket set.
5. Allow the old fluid to completely drain, then remove the transmission filter.
6. Install the new filter, ensuring it is properly seated.
7. Reinstall the transmission pan with a new gasket and torque the bolts to manufacturer specifications.

3. Inspect and Replace Transmission Solenoids (if necessary)

Sub-steps:
1. Remove any necessary components to access the transmission solenoids.
2. Disconnect the wiring harness from the solenoids.
3. Use a multimeter to test each solenoid for proper resistance and functionality.
4. If a solenoid is faulty, replace it with a new one.
5. Reconnect the wiring harness and any removed components.

4. Road Test

Sub-steps:
1. Reconnect the battery and start the engine.
2. Allow the engine to warm up and check for any leaks.
3. Take the vehicle for a test drive to monitor shifting and performance.
4. Check for any error codes again after the test drive.
