I've been thinking more and more about this recently. I don't see why it wouldn't be possible to bypass the ATF/water heat exchanger and mount a dedicated ATF cooler in front of the drivers wheel. A thermostats such as Earl's 501ERL could be used to keep the temperature in the operating range. I don't know this for certain, but I would have to assume the engineers at ZF designed the transmission to operate with the fluid above ambient.
My car did not come with an oil cooler so I plan to retrofit one as outlined here:
This same approach should work in front of the drivers side wheel for an ATF cooler.
I agree the best thing to do to protect the auto tranny is to keep the fluid temp n check.
