Just bought first gen4 Sable, '05 24v wagon. Duratec motor new to me, so is gen 3 and 4. Where is the transmission cooler? Better yet, how does the transmission keep cool? I only see the lines go into the radiator and back into transmission. Is that good enough? On the older ones had a line that went to the front of car and back, also going into radiator, and even then the transmissions had cooling problems, had to install aftermarket cooler.
