How do you check transmission fluid

Hey, my name is Dusty and I'm one of the auto experts with RepairPal's Car Genius team here to help! That'll depend on the specific transmission that's in your Enclave. Automatic transmission will have a few options, some may have a traditional dipstick tube that is used to refill the transmission, but these are becoming less common. Others use an overflow system that also requires special tools to fill the unit, as well as a diagnostic scan tool capable of accessing the transmission fluid temperature, and a specific set of steps to be performed while monitoring the data, which may include adding more fluid during the process. This is because the fluid expands, and contracts as things heat up, or cool down, which can affect the fluid level.
