why does my Volkswagen Golf MK6 (2009-2014) transmission jerk when shifting?

Solution

1. Preparation

• Tools Required: OBD-II scanner, socket set, torque wrench, transmission fluid pump, fluid catch pan.
• Safety Warnings: Ensure the vehicle is on a level surface and securely supported with jack stands.

2. Fluid Change

1. Drain Old Fluid

   • Place the fluid catch pan under the transmission pan.
   • Remove the transmission pan bolts using a socket wrench.
   • Carefully lower the pan and allow old fluid to drain completely.

2. Replace Filter

   • Remove the old transmission filter and discard it.
   • Install the new filter, ensuring it is seated properly.

3. Reinstall Pan

   • Clean the mating surface of the transmission and the pan.
   • Install a new gasket or use sealant as required.
   • Reattach the transmission pan using the torque wrench to tighten the bolts to the manufacturer’s specifications (usually around 8-10 Nm).

3. Fluid Refill

1. Add New Fluid
   • Use a transmission fluid pump to fill the transmission with the appropriate type of fluid (refer to the owner's manual for specifications).
   • Check the fluid level using the dipstick, adding fluid until it reaches the correct level.

4. Reset Transmission Control Module

1. Clear Codes
   • Use the OBD-II scanner to clear any transmission-related error codes.
   • Reconnect the battery if it was disconnected and perform a reset if necessary.
