Tranny cooler external cooler lines.

Anyone here know where I can get factory grade line splicing fitting (hose to hose) to extend the factory transmission line from the radiator to the external cooler needing to be added
(Toyota in their wisdom discontinued this on my 2023 trd raco). A metal line would be fine, also.
The factory line to the transmission obviously is too short to reach an external cooler behind the grill.

 

you can buy oem from toyota , or you can buy aftermarket like a derale

 

Added a Derale to my 03 Tundra that was seeing 225°+ temps whilst traversing the summertime mountains and deserts of Baja. IT MADE ZERO DIFFERENCE via ScangaugeII. Best bet was to run with overdrive off when the temps started to spike over 210. YMMV.

 

I too was surprised that it was discontinued in my 21 Sport. But come to find out it was kinda useless anyway. I started with one large add on and then went to two. I am super pleased with the results. Maybe some helpful info. here. I bent up metal lines to the coolers and just used very short rubber lines to make the connections. All with double clamps. No worries towing a trailer now.
