6.7 with Ford 6R140 transmission
Can you change the fluid in this tranny DIY like you could the old 5R by draining the pan then disconnecting the cooler lines, starting the truck and drain and fill at the same time to remove the rest...

Do not add any additives to the LV transmission fluid. Also Ford recommends the transmission fluid to be changed at 150k miles.
I plan on having mine chaged at around 100k miles.
