why does my BMW X5 G05 (2019-2024) transmission make a whining noise while driving

Solution

1. Preparation

• Gather tools: OBD-II scanner, socket set, torque wrench, fluid catch pan, and safety glasses.
• Park the vehicle on a level surface and engage the parking brake.
• Allow the engine and transmission to cool down if recently driven.

2. Inspect and Replace Transmission Fluid

• Inspect Fluid: Remove the transmission dipstick (if equipped) and check fluid level and condition.
• Drain Fluid: Place a fluid catch pan under the transmission drain plug. Remove the drain plug and allow fluid to fully drain.
• Replace Filter (if applicable): Remove the transmission pan (if equipped) to access the filter. Replace the filter with a new one.
• Refill Fluid: Replace the drain plug and refill the transmission with the manufacturer-recommended fluid type using a funnel. Refer to the owner's manual for the correct fluid capacity and type.
• Torque Specifications: Ensure the drain plug is tightened to the manufacturer’s specified torque.

3. Inspect and Replace Transmission Mounts (if damaged)

• Remove Components: If necessary, remove any components obstructing access to the transmission mounts.
• Inspect Mounts: Check the mounts for cracks, separation, or excessive wear.
• Replace Mounts: If damaged, remove the old mounts and install new ones, tightening to the specified torque values.

4. Test Drive

• After all repairs, take the vehicle for a test drive to ensure the whining noise has been resolved and shifting is smooth.
