McConaughey Report post Posted March 23, 2022 At what mileage should the transmission fluid be changed? I don't see it in the manual nor can find anything from Lincoln that supports what the dealership told me: 60,000 miles. Share this post Link to post Share on other sites
akirby Report post Posted March 25, 2022 Officially it’s “lifetime” which is 150k miles. Unofficially somewhere between 30k and 60k. Share this post Link to post Share on other sites
enigma-2 Report post Posted April 12, 2022 As Akirby stated, it's 150k miles. It's page page 492 of the owners manual. The manual also states 30,000 miles if you tow a trailer, have a lot of idling or primary low speed driving (city driving), driving in dusty or sandy conditions (pg. 493). It certainly can't hurt to change it more often. Share this post Link to post Share on other sites
