Alright, when is the time to change transmission fluid? Well, that is typically 24,000 to 30,000 miles or 2 to 3 years. The fact of the matter is the transmission fluid breaks down and it gets dirty over time. So, you want to clean the inside of the transmission, which means that you have to put a chemical in there and you have to use a machine to get rid of all the dirt and everything inside the transmission.
