so no heat exchange between the radiator and the tranny fluid ? do coolant lines run to the transmission or the cooler. Having no drain plug on what some would consider a heavy duty vehicle is cheap , dropping a pan can be messy. I'm used to using the tranny lines running to the radiator to do a flush. But I do believe ATF and the auto boxes themselves can tolerate longer maintenance periods than vehicles in the past, still highly variable though on operating conditions but if it's tow rated to 7,500 lbs must have decent ATF cooling. Dipsticks were a nice way to ascertain the condition of the fluid, but now even the drain plug is gone.As nice as that can be they can't do that on the ranger. The reason is the cooler is mounted on the side of the transmission and the linea go straight into the transmission.
