- After a major service: If you’ve recently had your engine oil changed or other major maintenance performed, it’s wise to check the transmission fluid as well.
- If you notice any unusual symptoms: If you experience any of the symptoms mentioned above, such as rough shifting or slipping gears, you should immediately check your transmission fluid.
