Ok, please explain to me how you fill up, from the bottom. Is the drainplug on these newer transmissions not a "drainplug" in the traditional sense, but a check valve. I don't see how you can pump fluid up and into the tranny through a drainplug hole, without it coming back out. What happened to the trainplugs on the torque converter, which is where the bulk of the fluid is?

Thanks
