Trans Cooler Lines

Just bought a B & M super trans cooler and trying to determine which line should be coming into the cooler from the transmission. My truck didn’t come with an trans cooler setup so I’m just adding it on. It’s on a 2018 Tacoma SR 4x2 Access Cab. Also would I just plug up existing metal lines?

 

No plugging the radiator tubes...

 

There's a thread on here that shows how to do it. If I find it I'll share it. BTW, I did it on my other tacoma and it's an easy install

 

Here you go... https://www.tacomaworld.com/threads/3rd-gen-tacoma-transmission-cooler.546637/. Good luck

EDIT: Before you do the install make sure you get a quart of the ATF (Automatic Transmission Fluid) at your dealer. You're going to need it for the install

 

Good tip. I assume you will spill some & some increased capacity as well

 

Appreciate the diagram, I was looking everywhere for some type of diagram but not luck. But, got it all mount and done up. Will post picture and also did an in-line filter
