Ill just add one interesting tidbit,
My understanding is that the trans coolant lines reduce your trans temps but this design's primary focus is to help keep the motor cooler and due to the tranny's close proximity to the motor (i know this is obvious) it does dissipate some thermal energy.
in other words, if my understanding is valid-true, the auto transmission itself doesnt need to be cooled which is interesting for some reason.
Doubt it. The fluid needs to be cooled when roaming around in low speeds in hot environments. Heat is the only thing that kills fluid and an oversize pan and cooling system (radiator) prevent that from happening.
