I just bought a 2015 GMC Terrain SLE used. It has 127k miles on it. I tend to keep cars a long time. (Last was a 2004 Chevy Tracker zr2/Suzuki Vitara at 18 years old and 265k miles).
Is it still safe to drain/fill the tranny fluid?
I am very new to cars and trying to learn as much as I can. I do have a 2019 GMC Terrain SLT with 56000 miles that runs great but I never had any of the following checked:
Engine air filter
Cabin air filter
