2. Allow the old transmission fluid to completely drain into a suitable container.
3. Replace the drain plug and torque it to the manufacturer's specifications (usually around 25 Nm).
4. Remove the transmission fluid dipstick and use the fluid pump to refill with new, manufacturer-approved transmission fluid until it reaches the proper level on the dipstick.

3. Reset Transmission Adaptive Settings

Sub-steps:
1. Reconnect the battery and start the engine.
2. Use the OBD-II scanner to access the transmission control module.
3. Follow the prompts to reset the transmission adaptive settings.
4. Turn off the engine and restart it to complete the reset.

4. Software Update (if applicable)

Sub-steps:
1. Check the BMW service website for any available TCM software updates.
2. If an update is available, connect the vehicle to a BMW-compatible diagnostic tool and follow the instructions to update the software.

5. Road Test

Sub-steps:
1. Drive the vehicle under various conditions (stop-and-go, highway speeds) to ensure the jerking issue has been resolved.
2. Monitor for any error codes or warning lights during the test.
