Just wondering if anyone who has installed an aftermarket cooler on their F150 4R70W tranny which lines they are on the driver's side of the radiator. I need to know which one comes from the tranny and which one goes back to the tranny to mount my B&M aftermarket cooler because I don't want to have it go through there, then be heated up in the radiator.

Mine has a line that goes into the top of the rad and a line out the bottom.

I tried calling B&M but was on hold waiting to talk to a tech for over 1/2 hour and gave up.

Help?

 

The line on top is coming from the transmission and going into the internal cooler. The line on the bottom is leaving the internal cooler and returning to the transmission.

Good luck.

 

Thanks for the QUICK reply!
