When should I change the transmission oil in a BMW M3?

I just bought a used BMW M3 and I'm not sure when I should change the transmission oil. Can you give me some advice?

It is recommended to change the transmission oil every 60,000 miles or every 5 years, whichever comes first. However, if you frequently drive your BMW M3 in harsh conditions, such as stop-and-go traffic or extreme weather conditions, it is best to change it more often, approximately every 30,000 miles or every 3 years. This will ensure optimal performance and longevity of your transmission. As always, it is important to consult your owner's manual for specific recommendations for your vehicle.

If you're unsure about when the transmission oil was last changed, it's better to err on the side of caution and change it now. Old and dirty transmission oil can cause issues such as rough shifting and decreased fuel efficiency. It's better to take preventative measures and change the oil rather than wait for a problem to arise. Plus, it's a relatively simple and inexpensive maintenance task that can save you from more costly repairs in the future.
