Solution

1. Preparation

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

2. Check and Replace Transmission Fluid

Sub-steps:
1. Remove the transmission dipstick and check fluid level.
2. If fluid is low, add the recommended fluid type (typically Hyundai ATF SP-IV).
3. If fluid is dark, burnt, or contaminated, proceed to drain and replace.
Tools Required: Fluid pump, funnel, drain pan.

3. Inspect and Replace Transmission Filter

Sub-steps:
1. Remove the transmission pan bolts using a socket set.
2. Carefully lower the pan and drain the fluid into a pan.
3. Remove the old filter and replace it with a new one.
4. Clean the transmission pan and replace the gasket.
5. Reinstall the transmission pan and torque bolts to manufacturer specifications.
Tools Required: Socket set, torque wrench, gasket scraper.

4. Test and Replace Transmission Solenoids (if necessary)

Sub-steps:
1. Remove the transmission pan as done previously.
2. Locate the solenoids and disconnect the electrical connectors.
3. Remove the faulty solenoids and replace with new ones.
4. Reassemble the transmission pan and ensure all connections are secure.
Tools Required: Socket set, screwdriver, torque wrench.

5. Reconnect Battery and Road Test

Sub-steps:
1. Reconnect the negative battery terminal.
2. Start the engine and allow it to warm up.
3. Shift through all gears and check for slipping.
4. Conduct a road test to ensure proper operation.
Tools Required: None specifically, but ensure proper functioning of OBD-II scanner for final checks.
