  • Why are Transmission Coolers Installed on the Fluid Return Line After the Radiator Mounted Cooler
  • The biggest reason that transmission cooler manufacturers and vehicle manufacturers want transmission coolers installed after the factory cooler rather than before it is because the transmission cooler in the radiator is surrounded by the coolant in the radiator.

  • Why Route Transmission Fluid First Through the Factory Cooler then Through Supplemental Cooler
  • The factory transmission cooler in most vehicles is integrated into the radiator. What this does is actually warm the cooler to the temperature of the radiator. A supplemental cooler does not touch the radiator so it will actually stay cooler than the factory cooler. So if you were to run the fluid through the supplemental cooler first you would cool the fluid and then once it went through the factory cooler it would warm back up to a certain extent. So the best way to route the cooler...

  • Do I Need to Identify Transmission Cooler lines to Run an Aftermarket Cooler In-Line with Factory

  • Will an Auxiliary Transmission Cooler Replace a Factory Radiator on 2006 Nissan Frontier

So because of that it would be a waste to install a transmission cooler before the factory cooler since the fluid would...
