my Genesis G70 has a hard time shifting gears, what's wrong

Solution

1. Preparation

• Gather necessary tools and parts.
• Ensure the vehicle is on a level surface and secure it with jack stands.
• Disconnect the battery to prevent electrical shorts during repair.

2. Check and Replace Transmission Fluid

• Fluid Level Check:
  • Remove the transmission dipstick (if applicable) and check fluid level.
  • If low, add the manufacturer-recommended transmission fluid.
• Fluid Replacement:
  • Drain the old transmission fluid using a drain pan.
  • Replace the transmission filter if applicable.
  • Refill the transmission with the correct type and amount of fluid as specified in the owner's manual.

3. Inspect and Replace Transmission Components

• Inspect the Clutch (Manual) or Torque Converter (Automatic):
  • For manual transmissions, check the clutch pedal for proper engagement and replace it if necessary.
  • For automatic transmissions, check the torque converter for signs of failure and replace it if necessary.
• Transmission Control Module (TCM):
  • If the TCM is found to be faulty during testing, replace it with a new unit.

4. Reassemble and Test

• Reassemble any components removed during inspection.
• Reconnect the battery.
• Clear any error codes from the vehicle’s computer using the OBD-II scanner.
• Test drive the vehicle to ensure proper shifting and operation.
