Solution
1. Preparation
  • Ensure the vehicle is securely parked on a level surface.
  • Disconnect the battery to avoid electrical shorts while working on the transmission.
  • Gather necessary tools and parts.
2. Drain Transmission Fluid
  • Place a drain pan under the transmission pan.
  • Remove the transmission pan bolts and carefully lower the pan to drain excess fluid.
  • Dispose of old fluid according to local regulations.
3. Replace Transmission Filter
  • Remove the old transmission filter and inspect for debris or damage.
  • Install a new transmission filter, ensuring it is properly seated.
4. Inspect and Clean Transmission Pan
  • Clean the transmission pan thoroughly to remove any metal shavings or sludge.
  • Check the pan's magnet for buildup and clean it.
5. Reassemble Transmission Components
  • Reinstall the transmission pan with a new gasket or sealant as recommended by the manufacturer.
  • Torque the pan bolts to the specified value (typically around 10-12 Nm, but verify with manufacturer specifications).
6. Refill Transmission Fluid
  • Use a funnel to pour the appropriate type and amount of new transmission fluid (refer to owner's manual).
  • Start the engine and let it idle, shifting through all gears to circulate the new fluid.
7. Test the Transmission
  • With the engine running, check the transmission fluid level and adjust if necessary.
  • Perform a road test to confirm that the slipping issue has been resolved.
