I am installing a trans cooler on my 700r4, which lines on the radiator are inlet and outlet? Does the aftermarker cooler need to go before the radiator cooler or after? Thanks!

 

The bottom line is the out line, put the cooler after the radiator. This does the best job.

 

On the rad? I thought the bottom was the inlet.

 

I think it's just like the radiator flow. In the top and out the bottom.

I think Pro Built is saying the bottom line is out from the tranny, or saying it another way, the supply into the factory cooler. That's the way I recall it being.

Mount the aftermarket cooler in front of the radiator, and run the top line from the radiator cooler to the aftermarket cooler, then back to the top hard line that goes back to the tranny.

Right, Dana?
