why does my Genesis G70 transmission jerk when shifting gears

Solution

1. Preparation

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

2. Check and Replace Transmission Fluid

• Tools Required: Funnel, fluid pump, socket set
• Sub-steps:
  1. Locate the transmission dipstick and remove it to check fluid level.
  2. If the fluid is low, add the manufacturer-recommended transmission fluid.
  3. If the fluid is dark or has a burnt smell, drain the old fluid using a fluid pump.
  4. Replace with new transmission fluid, ensuring it meets manufacturer specifications.
  5. Recheck fluid level and top off as necessary.

3. Inspect and Replace Transmission Control Module (if necessary)

• Tools Required: Socket set, multimeter
• Sub-steps:
  1. Locate the TCM, usually found near the transmission.
  2. Disconnect the electrical connector carefully.
  3. Use a multimeter to check for proper voltage output.
  4. If faulty, remove the TCM using the socket set and replace it with a new unit.
  5. Reconnect the electrical connector and verify secure mounting.

4. Examine and Replace Worn Components

• Tools Required: Socket set, torque wrench
• Sub-steps:
  1. If jerking persists, inspect the transmission for worn components such as clutch packs or solenoids.
  2. Remove the transmission pan using a socket set to access internal components.
  3. Inspect for wear on clutch packs and replace if necessary, using manufacturer specifications for torque when reinstalling.
  4. Reinstall the transmission pan with a new gasket to prevent leaks.
