why does my Skoda Octavia's transmission slip when accelerating

Solution

1. Preparation

• Gather tools and parts needed for the repair.
• Disconnect the vehicle’s battery to prevent electrical shorts.
• Ensure the vehicle is on a level surface and secure it with wheel chocks.

2. Check and Replace Transmission Fluid

• Tools Required: Transmission fluid pump, fluid catch pan, socket set.
• Sub-steps:
  1. Remove the transmission pan using the socket set to access the fluid.
  2. Drain the old transmission fluid into the catch pan.
  3. Inspect the old fluid for metal shavings or burnt smell, which indicates internal damage.
  4. Replace the transmission filter if necessary, following manufacturer specifications.
  5. Reinstall the transmission pan with a new gasket, torquing to the manufacturer’s specifications.
  6. Refill the transmission with the appropriate type and amount of fluid as specified in the owner’s manual.

3. Inspect and Test Components

• Tools Required: Multimeter, transmission pressure gauge.
• Sub-steps:
  1. Test the throttle position sensor for proper operation using the multimeter.
  2. If faulty, replace the throttle position sensor with a new unit.
  3. Test the transmission fluid pressure using a pressure gauge; ensure it meets manufacturer specifications.
  4. If pressure is low, inspect the pump and internal components of the transmission for wear or damage.

4. Final Checks and Assembly

• Tools Required: Torque wrench.
• Sub-steps:
  1. Reconnect the battery and clear any diagnostic trouble codes.
  2. Start the engine and allow it to warm up, then check the fluid levels again.
  3. Test drive the vehicle to ensure that the transmission shifts smoothly without slipping.
