Default 4eat radiator replacement, Have trans cooler, but confused (pics)

I understand that The OEM radiator has a tranny cooler.

I had a TC done years ago. The guy also put in a trans cooler for me.

I went under the car and took a look, to see if I need to do anything special to swap the radiator. I'm using a Koyo OEM style radiator.

I believe the spout on the left is in, and the spout on the right is out.
What I THINK he did was take the return line (RED) from the right spout, and route it up to the trans cooler. Then ran a new return line (BLUE) across the back and connected it to the return to the transmission.

So if I swap the radiator, I only have to mirror what he did, and I'm good?



(I guess what confuses me, is why didn't he just take the feed line (uncolored) and run the red line to where that comes from?)

I am not sure what the guy did, but I do remember a thread that mentioned the eed or the bypass to help heat the tranny faster inthe winter. Not sure if you still have the stock cooler as well. The routing of the lines could be related to that. Search tranny cooler and you might find it.

If its been working I would just mirror what he did.

Yeah just do as he did and you should be fine. I did similar with my tranny cooler except I actually put my tranny cooler before my stock cooler where it goes into the radiator.

This allows your aftermarket cooler to take away most of the heat before it enters into your radiator cooler which isn't designed to deal with extreme temps, plus that way it's also the last cooler so it can help actually heat up your tranny fluid faster from the temp from the radiator during colder winter starts.

No biggie really though on the order, it looks good to me! My OEM radiator actually just cracked though and I just went with a aftermarket koyo and am just going to run my aftermarket tranny cooler solo. I dont really want to go back to the stock radiator style only to have the same thing happen a few years later from the plastic tanks on it.
