Ive got a aftermarket trans cooler I'm wanting to install, I want to bypass the radiator and go straight to the cooler. Wondering if anyone knows what size and thread the transmission line fittings are cause I want to screw a barbed fitting to it and use some rubber hose to the cooler and so I could go back to original configuration if I wanted too.

There's a coupling in the trans lines right at the bell housing. That's where I switched from the stock lines to the aftermarket line and ran directly to my trans fluid cooler.

Summit sells the two adapters. They work great.

I can't remember the part number offhand. Call summit.

Just cut the metal lines that go to the radiator and use fuel inj hose from the metal lines to the cooler. Thats what I did. 6yrs without issues or leaks and I drag and road race the car.

On a 2000, the upper line is 5/8x18 reverse flare. The bottom is probably the same. I run a 3200 stall and go through the radiator first. Its below 190 degrees even in the summer.

No i didn't call summit, I just thought that if someone knew the size I could find a fitting locally. 5/8 x 18 reverse flare, ok thanks. Ya I thought about just cutting them and flaring them them clamping some rubber hose to them but if I ever decided to put back to stock I wouldn't be able to do that.
