why does my Genesis G70 transmission slip when shifting?

Solution

1. Preparation

• Tools Required: Vehicle jack, jack stands, OBD-II scanner, socket set, torque wrench, multimeter, transmission fluid pump.
• Safety Warnings: Disconnect the battery before working on electrical systems. Ensure the engine is cool before inspecting the transmission fluid.

2. Check and Replace Transmission Fluid

1. Locate the Transmission Dipstick:
   • Remove the dipstick and wipe it clean with a lint-free cloth.
2. Check Fluid Level:
   • Insert the dipstick back in, then remove again to check fluid level. If low, proceed to add fluid.
3. Fluid Replacement:
   • With the vehicle at operating temperature and parked on a level surface, drain the old transmission fluid using a fluid pump.
   • Replace the transmission filter (if applicable) by removing the pan and replacing the filter.
4. Add New Fluid:
   • Reinstall the pan, ensuring to torque bolts to manufacturer specifications (typically around 10-12 ft-lbs).
   • Add new transmission fluid through the dipstick tube; use the manufacturer's recommended fluid type.

3. Inspect and Replace Transmission Solenoids

1. Access the Transmission:
   • Remove any components obstructing access to the transmission solenoids.
2. Test Solenoids:
   • Disconnect the electrical connector and use a multimeter to check resistance; refer to the service manual for specifications.
3. Replace Faulty Solenoids:
   • If solenoids are faulty, remove and replace them, ensuring to torque new solenoids as specified.

4. Conduct a Test Drive

• After completing repairs, perform a test drive to ensure smooth shifting and verify the issue is resolved.
