Can anyone tell me exactly where the top one, of the two fluid tubes, goes inside the transmission?

Thanks for the help.

One is "overflow" from trans main pump, IOW That is bleed/bypass oil output from "pressure regulator"
Other just drains to sump.

Not much pressure on coolant lines.

I had a TSB that said which port is out and in on several trans types but I can find it right now.

The bottom line is hot oil from the torque converter to the cooler. The top line is cooled oil returned from the cooler. It is routed into the internal lube circiut to lube the bushings in the clutch drums,bearings,and geartrain. normal pressures in this circuit are 30-110 psi depending on line pressure.
