why does my Genesis G70 transmission slip when shifting

Solution

1. Preparation

• Gather all necessary tools and parts.
• Ensure the vehicle is parked on a level surface and secure it with wheel chocks.
• Disconnect the negative battery terminal to prevent electrical shock.

2. Check and Change Transmission Fluid

• Sub-steps:
  1. Remove the transmission dipstick and check the fluid level.
  2. If low, add the manufacturer-recommended transmission fluid.
  3. If fluid is burnt or contaminated, proceed to change the fluid.
  4. Place a drain pan under the transmission pan.
  5. Remove the transmission pan bolts using a socket set and carefully detach the pan.
  6. Drain the old fluid and inspect for metal particles or debris.
  7. Replace the transmission filter according to the manufacturer’s guidelines.

3. Inspect and Repair Transmission Seals

• Sub-steps:
  1. With the transmission pan removed, inspect all seals and gaskets for wear.
  2. Replace any damaged seals with new ones to prevent fluid leaks.
  3. Reinstall the transmission pan with a new gasket, torque bolts to the manufacturer's specifications.

4. Update Transmission Control Module (if necessary)

• Sub-steps:
  1. Reconnect the battery.
  2. Use a diagnostic scanner to check for TCM updates from the manufacturer.
  3. If an update is available, follow the scanner instructions to update the TCM firmware.
