Good morning Scotty,
I own a 2016 Toyota Highlander XLE (Non-Hybrid) with 90,000 miles. I drive normally (no towing or off-road) and basically these are highway miles. Should i replace transmission fluid? Car shifts fine and no issue with it, just wanted to know if it wise to change fluid as car gets higher mileage or just leave alone. I thank you in advance for your time and hope you keep making helpful videos.
Regards,
Jayalen
Yes, it should be fine to change the transmission fluid. Perform a drain and fill and change the filter (if applicable). Be sure from this point onward to stay on top of the transmission fluid change intervals in order to get as much life out of the transmission. Also for your knowledge see our ATF sticky:
