ATF Cooler installation orientation

[Pdesign1]

Does orientation of ATF cooler matters during install?

 

I mean the inlet/outlet ports facing top, side or bottom.

 

I am looking at this B&M ATF cooler that has a self regulating/bypass feature in the first 2 plates nearest to inlet/outlet port.

 

1st & 2nd plate bigger orifice, cooler/thick oil will bypass rest of the plate. Hot/thinner ATF goes on thru rest of plates.

 

I wonder if orientation affects this feature. Is it actually possible to overcool the ATF in SG/MY climate?

 

My car actually have an ATF cooler already (cooler type, not go thru radiator type). But I feel that it is more suited for stock car application, furthermore it is sited between AC condenser & radiator with a terribly hot engine bay.

 

Appreciate any opinions. Thanks.

Bro, for my Mz3 it originally comes with a ATF cooler liao but think is a small one hence i did not add on any additional ATF cooler

 

However, some Bros from the Mazda Club add on another extra ATF Cooler ontop of it and has heard no complaint from them til date

i thought remember reading somewhere that it will only bypass(?) to the cooler above a certain temp.

 

also there is an optimum temp that engines/systems work at, so overcooling is no good. ? let me know if I'm off the mark. thanks.
