Good pictorial install writeup, but
My feelings are !!
1)-bottom aux cooler line should go to the Bottom tranny line (hot oil)-
2) the top aux cool line should go to the top tranny line (return cooled oil line)-
Why, because the (HOT OIL), bottom line, should be PUSHED (tranny oil pump)up thru the aux cooler, so it stays in the cooler LONGER for cooling, rather than gravity, pulling it down, quickly !!
I say this because I've by passed the A/C cooler alltogether !
