Re: E4od Transmission
FYI - If you drain the converter, later, when you are putting ATF back in and have quite a few quarts in, stop and run it just for a moment so the trans pump can pressurize and refill what were air spaces with fluid. I didn't do this on an AOD trans once, and as I refilled, and got within quarts of full, it started coming out of the vent on the top of the trans case. 'Course, I didn't see this till a red wave moved across the floor! What a mess! Hydro fluid is almost impossible to wipe dry! So now I always run them for a moment.
If you don't drain the converter, then that's not a problem. But Ford has been nice enough to leave a converter drain plug, so I always use it.
