2014 Ram 8HP70 Fluid Change
#3
#4
#5
the entire system capacity is 9.7 litres. A pan drop would probably change 4- 6 liters? I would be reluctant to do use an exchange machine on this transmission unless it was a dedicated for zf 8 speed fluid; the factory doesn't want you adding dye tracers in the fluid as they aren't compatible... and that's a small amount of fluid.
if you want more fluid removed...do the pan drop...fill it. drive it for a week...drop the drain plug and refill it. repeat. after that for future service...leave the filter and just change the fluid. 80% of the debris that circulates in a transmissions life is removed at the first fluid and filter change.
there is a severe service interval for trans fluid changes in the maintenance schedule...follow that.
