Solution

1. Preparation

Tools Required: OBD-II scanner, socket set, torque wrench, multimeter, fluid catch pan.
Ensure the vehicle is on a level surface and securely supported with jack stands.
Disconnect the battery to prevent any electrical shorts.

2. Check and Replace Transmission Fluid

Sub-steps:
1. Locate the transmission dipstick or fill port.
2. Remove the dipstick and check the fluid level; add fluid if low.
3. If the fluid is dark or smells burnt, drain the old fluid using a fluid catch pan.
4. Replace with the manufacturer-recommended transmission fluid type.
5. Refill to the recommended level.

3. Inspect and Replace Transmission Filter

Sub-steps:
1. Remove the transmission pan using a socket set; ensure to catch any remaining fluid.
2. Take out the old filter and inspect for clogs or debris.
3. Install a new transmission filter and secure it properly.
4. Reinstall the transmission pan using a new gasket, torquing bolts to the specified value (typically 8-10 Nm).

4. Test Transmission Solenoids

Sub-steps:
1. Disconnect the electrical connector from the solenoids.
2. Using a multimeter, check the resistance across the solenoid terminals against specifications.
3. Replace any faulty solenoids with new ones as necessary.
4. Reconnect the electrical connector securely.

5. Reassemble and Test

Sub-steps:
1. Reconnect the vehicle battery.
2. Start the vehicle and check for any warning lights.
3. Conduct a test drive to ensure the shifting issue is resolved.
