New trans cooler

[Mister Pinky]

Hmm...makes me wonder if there’s different sized trans coolers depending on what engine you got in said F-350.

Anyone have results? Temp differences before and after?

I just replaced my stock one with the "Saudi" larger OEM Ford one just today. I started the truck up from a cold start and let the truck warm up. The temps returned back to normal pre-replacement. Then I took a short trip 30 miles and drove with a 91 octane performance tune on the highway 70-80 mph, outside temps 89 deg F and high humidity FL weather. The trans temp were at same 197deg F pre-replacement. Have not loaded up or towed yet to see if any change. I'm guessing since its thermostat driven, the upgraded cooler will just help to keep the temp at the 197 degs with better cooling.
