2015 GMC Terrain needs the trans fluid changed out and I'm curious about the pros and cons of doing it myself vs having it flushed and refilled at a service location.
I do all my own fluid changes on all vehicles so the work itself is no big deal. The fact that I need to drain and refill the transmission two or three times (with a few hundred miles between) means making time for the task 2 or 3 times, buying transmission fluid 2 or 3 times and frankly 2 or 3 chances to make a mess of my driveway.
Flush and refill is a one-and-done, but appears to have the risk of sediment being disturbed and causing blockage issues down the road.
What say you, BARF?
