PPE Trans Pan Cover (regular capacity) - does drain hole loc allow complete pan drainage?

[SpifNup]

Ad pics for regular capacity PPE transmission oil pan (not deep version) for 10R80 always seem to show drain hole located near shallow (less tall) end of pan. This strikes me as odd (for pan draining).

By contrast, PPE deep pan and other manufacturers' replacement metal pans seem to show drain hole locations at deeper end of their pans.

For those who have purchased this particular PPE metal pan, is the drain hole actually located as indicated in ad pics?

If so, will transmission fluid in pan 'fully drain' when drain plug removed?

Perhaps pan mounting is tilted (due to transmission shape & location) to alleviate full pan drainage concern.

Perhaps one-quarter to one-half inch of fluid remaining in a dropped pan (after draining much as possible via drain plug) is normal or necessary for some reason.

But I'd prefer to minimize chance of spills from any pan tip or drop (necessary or accidental), when removing metal pan to inspect/clean, plus change filter.

Curious, before I pull the trigger on metal pan to replace factory plastic pan.

Thanks for any feedback on these transmission fluid pan drain locations.

If I remember from when I installed it, it will all drain except for a minor bit around the plug lip. However, I could be visioning wrong.

The plug is near the back. While it looks like it is 'higher' it actually is in the low point of the pan.

Thanks Randy & Shawn for replies. Things make more sense now.

I ordered PPE regular (not deep) fluid pan. Should be fine.

Apparently (matches guess of mine) mating surfaces plane (pan & trans) angles down (toward shallow, less tall end of pan). Thus drain at shallow end of pan should work fine.

For deep[er] pan models, bottom of deep end of pan must now be below bottom of shallow end of pan (due to increased height/depth of pan at tall end). Added depth then alters end where pan is lowest (overcoming mounting slant of mating surfaces) & thus drain loc shifts by design.

I hadn't grasped this during my initial puzzlement yet figured there had to be an explanation for different drain locations on different pans.

Per PPE, the shallow pan holds about 3/4 of a quart more, so if you measure what you take out and are confused why it isn't the same level after you put the fluid back in, that's why.
