 A lot depends on the type of vehicle and how many miles are on it and the condition of the fluid. I'm going to let Desmond take that. Absolutely. So if you've been staying up on top of your maintenance and getting your transmission serviced every 30,000 miles and your fluid is nice and bright red and you're not having issues, a flush is completely fine. If you've fallen behind on your maintenance. Wait a second. I have a sound effect.
