How to Check the Transmission Fluid on a 1992 BMW 525i

1. Drive the 1992 BMW 525i around for about 10 minutes to heat the transmission fluid up. To be able to get an accurate transmission fluid reading, the transmission fluid has to be hot.
2. Park the 1992 BMW 525i and leave the engine running. Set the emergency brake and open the hood.
3. Locate the transmission dipstick on the back side of the passenger side of the engine. The transmission dipstick will have a small yellow handle.
4. Pull the transmission dipstick out and wipe the fluid off with a clean rag. Slide the transmission dipstick back in the tube and pull it out again. The transmission-fluid level should be between the two check lines on the dipstick. The bottom check line is the "Low" fluid line and the top check line is the "Maximum" fluid level. The transmission fluid must be between the two lines to be full.
5. Slide the dipstick back in the tube and close the hood. Turn the engine off.
