Transmission Cooler and Fan for a 2004 Honda Odyssey

Question:

1 Transmission cooler with fan combination for 2004 Odyssey. Has to be a pusher fan because cooler has to mount in front of condenser/radiator. No plans to tow but would like maximum cooling capability of atf fluid in traffic and stop n go in town driving. Which cooler design is most efficient, stack plate, plate and fin, or tube and fin? 2 Reference remote spin on atf filter mount kit #13090, is the filter installed on the outbound from trans before entering OEM radiator trans cooler or down stream of aux. trans cooler in return line to transmission? 3 The minimum micron rating a bypass valve required, if so what psi and is an anti drain back valve necessary in a trans filter?

The Tube and Fin style is the original way oil and ATF coolers were designed, so they will be the least efficient of the 3.

The Plate and Fin will be the most efficient of the base style coolers for standard vehicles. They offer very good cooling properties and are generally smaller in size. I suggest using # D13503.

The Stacked Plate style is the most effective style of cooler, but is generally used on larger vehicles and or work trucks. You can use # D53478 with the adapter # D98203, but you will need another adapter going to and from the transmission as it is a 1/2 inch barb whereas the standard would be 11/32.

I suggest the fan # FLX236 with both of the above options. This can be used as a pusher or puller if needed.

The # D13090 Would be installed on the return side of the transmission and the end of the circulating circuit.

The filter # D13092 that comes in the Derale # D13090 has a micron rating of 21. Anything finer would end up damaging the ATF. From what I could find, there should be no bypass needed.
