for the E40D, does changing the oil mess stuff up?

Transmission flushes have a bad wrap ( most likely from hack shops using snake oil chemicals ?)

basically they start the truck and let the transmission expel it's old fluid into the machine while the machine supplies clean new fluid to make up for the expelled fluid

so your tranny has no clue anything is going on and it won't dislodge any debris any faster than it would have dislodged anyway

does the truck have to be running when doing this, or is it like changing the motor oil?

you have options

you can do a pan drop and change just that fluid so maybe 1/3

and on your e4od it's simpler than the 5r I have to flush than since needs to be a heated flush due to the cooler bypass

I am sure We can find a "how to flush" if you want to go that way?

I like to so you can inspect the pan for debris

I also like to inspect or just replace the filter even if it's not required

if it's the rubber one it's a reusable non sealant type

cork isn't supposed to need sealant either but they aren't reusable
