Transmission oil cooler plumbing

[TomA]

Hello,
Can someone please tell me which cooler line (7 and 8) goes to which connection on the transmission (A or B)? I assume the outflow from the transmission goes to the bottom of the vertical cooler, but I don't know which is the outflow - A or B

my cooler is across the top of the trany. honesty I do think the direction matters. the fluid will flow either way with no restrictions thru the cooler. I'd set the hoses up economically to the cooler.

Thanks. I think on a vertically orientated cooler it does matter. If the oil comes in from the top it may just cascade down the tubes and not completely fill the cooler before it exits. When the oil comes in from the bottom the only way it can exit is to completely fill the entire tube and go out the top. Obviously completely filling the cooler will provide better heat exchange.

got it. odd the cooler would be mounted vertically. sorry couldn' help further but bottom up makes total sense.
