Default Trans cooler fittings (update)

Just purchased a 70274 trans cooler and plan to bypass the rad. and run it stand-alone. It has female 1/2" NPT fittings.
Question; does anyone know what fittings and line size I will need to fun it? I plan on running braided line from the most convienient point.
Thanks

These are the fitting I need to convert to AN6.


They are located right at the flywheel (they are disconnected when you pull the trans) but not sure what size and thread style. If I can get a couple of fittings to screw into the brass female connector and convert to AN6, I can pick up a couple of 5ft braided lines and I'm good to go:judge: I have the cooler to AN fittings worked out

They are regular old 5/8 #18 inch thread with a inverted flare . The fitting you need is russel #640380- this is steel. Or#640381 in aluminum. This fitting is a # 6 braided line size. What type hose are you going to use?

Ordered;
2- 100119, 1/2" NPT - 6AN fittings
2- 640380, 5/8" inverted flare - 6AN
2, 6ft, 6AN steel braided line.

Now I just need to pick up a couple of 5/8 IF caps for the old Rad lines.

Default update with results

Got everything installed this weekend (PITA by yourself )

My last noted results with stock cooler on 97* day were;
Coolant - 196
Oil temp - 215
Trans temp -210
I took it for a quick, 10 min highway run after the install and got the following results on a 94* day, no AC;
Coolant temp - 190
Oil temp - 203
Trans temp - 148

Today after church, we drove through town, stopped at a drive-through (for almost 10mins) cruised back through town and got the following on a 94* temp drive WITH AC:
Coolant temp - 204
Oil temp - 238
Trans temp - 163

This baby may cool TOO much
