Where do you check the transmission fluid level on a 2004 BMW 545i?

To check the Transmission Fluid level on a 2004 BMW 545i, locate the transmission dipstick, which is typically found near the back of the engine bay, near the transmission. Ensure the vehicle is on a level surface and the engine is warm. With the engine running, pull out the dipstick, wipe it clean, then reinsert it and check the fluid level against the markings on the dipstick. If necessary, add the appropriate transmission fluid through the dipstick tube.
