Engine + Transmission Oil Cooler Install

[SECURITY]

yeah that makes sense. well i guess with the kind of pressure the trans and engine oil will see it should be fine.

[Usual Suspect]

sorry to bring up an old tread, but it beats making a new one on the same topic.

before i start, when switched off, how high is the oil level relative to the standard filter locaion? (see attached pic (8.6k))

1).i was wondering about the different setups (in my case engine oil), but wouldn't #2 hold the oil during oil change, which means when the new oil is run thru the cooler, it mixes with the old stuff, reducing the life of the new oil before you've even pulled out of the driveway.

2).if the oil level is at level 2 in the pic, and the cooler is installed as per #1 or #3, wouldn't the cooler drain after driving, which would starve the engine on startup?

i'm probably just over reacting but its been bugging me.
