Just a Texan transplanted in the Rockies
I mean I don't plan on changing just the filter lol. I'd probably take the pan off to change the filer, top it off (since it is 2 gallons after all). Maybe drive it for a few miles then drain it again and refill.This belief needs to go away. Read my other posts about how the fluid stays dirty with just a filter change.
It did pull a gooseneck trailer before I had it so I wouldn't be surprised XD The transmission does operate very well, though, and always shifts properly. I never have rough shifts, and they get smoother with a trailer.If you have problems after a filter and fluid change the transmission was already worn.
And believe it or not, going up to 265/70r17 from my OEM 245/75R16 tires didn't feel any difference. In fact, after adjusting for the difference in tire height my mpg actually increased and it still towed well. It wasn't until I went up too 285s is where I felt the drag. That could also be because:
1. I went from Michelin highway tires to Nitto mud/all terrain tires
2. The added wind resistance from being a couple inches higher off the ground.
