A few thoughts:
From looking at the pictures of the pan (Pg 6), it seems obvious to me that as long as the vehicle is level side to side, that some minor unlevelness front to rear will not markedly change the actual fill level, as the plug is close to the front to rear center of the pan.
Page 7 shows a fill plug. I'm wondering if I can fill it from this location instead of the bottom plug, just using it to tell me when I've hit the full level.
As was stated above, pages 8 and 63 show a torque converter drain plug and bell housing access port. Does this mean that my 5R55W has this (I will crawl up under and check some day).
The valve body diagram on page 10 and accompanying legend on page 11 are inconsistent. This is a public service warning for those who might consider this a default to use as a guide instead of keeping track of bolts when doing valve body work. Specifically, Page 10 shows 8 "E" bolts but the legend says 7 on page 11, and there are 2 bolts labelled "G" on page 11, one stating one bolt and the other with 4 (reverse servo bolts), but only 4 are shown on page 10 (also on the reverse servo), so buyer beware.
I printed this out from the list of useful threads some time ago, in anticipation (and fear) of doing my tranny some day.
