how to fix transmission jerking when shifting in Skoda Octavia NFL (2020-Present)?

Solution

1. Preparation

• Gather tools and safety equipment.
• Ensure the vehicle is parked on a level surface and the engine is off.
• Disconnect the negative battery terminal to prevent electrical shorts.

2. Check Transmission Fluid

• Tools Required: Transmission fluid dipstick, funnel.
• Remove the transmission dipstick, clean it, and reinsert it to check fluid level.
• If low, add the manufacturer-recommended transmission fluid to the correct level.
• Inspect fluid condition: If dark or burnt, plan for a fluid change.

3. Change Transmission Fluid and Filter

• Tools Required: Socket set, torque wrench, drain pan, new transmission filter, new transmission fluid.
• Drain the old transmission fluid into a drain pan by removing the drain plug.
• Remove the transmission pan and the filter.
• Replace the filter with a new one and reinstall the pan with a new gasket.
• Refill the transmission with the appropriate amount of new transmission fluid, ensuring it is the correct type.

4. Inspect and Test TCM

• Tools Required: OBD-II scanner, multimeter.
• Reconnect the battery and use the OBD-II scanner to check for TCM-related error codes.
• If codes are present, repair or replace the TCM as necessary.
• If no codes are found, use a multimeter to test the TCM connections for continuity and proper voltage.

5. Throttle Position Sensor (TPS) and MAF Check

• Tools Required: Multimeter.
• Disconnect the TPS and MAF connectors and inspect for corrosion or damage.
• Use a multimeter to check the resistance of the TPS. If out of specification, replace it.
• For the MAF, check the voltage output with the engine running to ensure it is within the manufacturer’s specifications. Replace if necessary.
