How do you check the transmission oil on a BMW?

I drive a BMW. The shifting has been a bit noisy and rough recently. I think it just needs some transmission oil. What’s the best way to check a BMW’s transmission oil?

Noisy or rough shifting are telltale signs of transmission issues with your BMW, so taking a look under the hood is a great first step!
To check the transmission oil on a BMW, you’ll actually be checking the transmission fluid as cars don’t use oil for the transmission. To check the transmission fluid, you should:
  1. Park on a flat surface and let the engine run for a few minutes. The engine should always be warm before checking the transmission fluid.
  2. Open the hood and locate the transmission fluid dipstick. Typically, the transmission fluid dipstick is next to the oil dipstick, but you should consult the owner’s manual if you’re having trouble.
  3. Remove the dipstick and inspect the fluid on it. If the fluid is anything but clear with a slight pink hue, you should visit a mechanic.
  4. Clean off the dipstick using a rag and insert it back into the vehicle.
  5. Pull out the dipstick again and check the fluid level using the markings on the dipstick.
  6. Add transmission fluid as necessary, being careful not to overfill. Using a funnel may make this process easier.
If the transmission fluid level and quality look normal, but the problem persists, you should visit a mechanic to have the vehicle professionally serviced.
