I have been suspecting that I have overfilled my transmission, due to a problem with my dipstick tube position, but that is a separate topic. I have fixed the dipstick tube and am now ready to refill the system.
It is a 4r100 on a 98 Expedition.
Ford service procedure says to drain the pan, replace filter and drain torque converter, then refill with 6.5 quarts and adjust level after running through gears at operating temperature. I am under the understanding that the torque converter holds a couple quarts, but when I drained it, this much came out. I have yet to measure, but I think it might be 6-8 quarts.
I don't want to overfill again. Any advice? Do torque converters hold this much? Could it be excess from somewhere else in the transmission due to a previous overfill?
