Appreciate the input. I just went by what the mechanic said, I didnt know other than that. But it was expensive and I didnt really want to go the route of them doing a power flush again (not sure the exact term).No official interval for regular maintenance. You’re definitely on a shorter schedule than I am, I changed mine a couple weeks ago at 111,000.
I posted at the end of this thread here.
Transmission Fluid Change procedure
I did the three drain and fills method, I really see no need to drop the pan, replace the screen, clean the magnets unless you’ve been towing or are otherwise hard on your truck.
Maybe I would think differently if I had a lift.
I recommend this video as it was the easiest to follow and she’s fairly detail oriented.
