why does my BMW 5 Series F10/F11 (2010-2017) feel like it's slipping when I accelerate

Solution

1. Preparation

• Gather tools and parts required for the repair.
• Ensure the vehicle is parked on a level surface and the engine is turned off.
• Disconnect the battery to avoid electrical shorts.

2. Transmission Fluid Change

• Tools Required: Transmission fluid pump, socket set, torque wrench, fluid catch pan.
• Sub-steps:
  1. Locate the transmission drain plug and remove it using the socket set.
  2. Allow the old fluid to completely drain into the catch pan.
  3. Replace the drain plug and torque it to the manufacturer’s specification.
  4. Remove the transmission fill plug and use the transmission fluid pump to add new transmission fluid (ensure it meets BMW specifications).
  5. Check the fluid level by starting the engine and shifting through the gears while monitoring the level on the dipstick.

3. Inspect and Replace Transmission Filter

• Tools Required: Socket set, torque wrench, transmission filter replacement kit.
• Sub-steps:
  1. Remove the transmission pan by unscrewing the bolts with the socket set.
  2. Carefully take out the old transmission filter and replace it with a new one.
  3. Clean the transmission pan and apply a new gasket.
  4. Reinstall the transmission pan and torque the bolts according to specifications.

4. Check and Repair Drive Components (if necessary)

• Tools Required: Jack and jack stands, socket set.
• Sub-steps:
  1. Lift the vehicle securely using a jack and place it on jack stands.
  2. Inspect the driveshaft and CV joints for wear or damage.
