I wrote that wrong initially, should have gone to sleep!

I as gonna say, it should run through the radiator first, then the cooler, and back to the transmission

This is what makes sense. Use the radiator as a pre-cooler. It would seem that if I routed to the radiator last, the radiator would reheat the trans fluid to what ever the water temp was (over 210).

Thanks

Now which line is which top to bottom?

You can make the stock lines work with fittings to the 40 k cooler, flip the bottom bracket drill holes and reuse the stocks bolts. I made the bracket 1/4 aluminum.

I don't have a stock one. I have zero. Which line leaves the radiator to return tot he trans (our cooler in this instance) The bottom line from the radiator would make sense.

Fluid comes from the transmission and enters the bottom of the radiator and exits the top fitting. This is to keep air pockets from forming. So the line coming out the top of the radiator goes to the external transmission cooler. When we used the tube/fin style cooler, the exits were on the side and we plumbed into the bottom first and then the return came out the top. With them facing down, I reckon that it doesn't matter unless the manufacturer says so.

Doesn't matter but I just matched to my stock one with the Trucool
