Bypass radiator/tranny cooler combo?

"My" tranny gauge stays at 160 solo where my ECT stays around 190. Which way do you think the heat is going to go according to the 2nd LAW of thermodynamics?

The heat is going to go from the ATF that enters the bottom of the radiator which is probably close to 250 deg and with the temp at the bottom of the radiator being in general at least 20deg cooler than you 190 ECT reading the ATF will be cooled by that in tank OTW cooler NOT WARMED.

I think you would be best to just believe what MARK who is the TRUE EXPERT here and if you were to appreciate that the 160 you are quoting is generally the pan temp of the ATF and the ATF going into that OTW cooler has just left the torque converter and can typically run anywhere from around 220 to well over 300 deg along with the fact that the coolant temp in the bottom of the radiator where the OTW cooler is is cooler than what is typically measured as the ECT temp (the 190 in you example) the thermodynamic laws are being followed, it's just you are applying them with incorrect temperature where they actually apply.

I'm thru and if you want to try and convince someone, you need to be talking to MARK and not me since I completely agree with him and my understanding of what in general the various temps of both the ATF and coolant are in each system at the points of interest as they apply to this discussion, they make complete sense to me and are consistant with what MARK has proven.
