I’m in the process of converting the factory lines over to stainless braided with AN fittings and have the correct fitting for the 4l8E and the tru-cool however the 5/8x 18 I’ve found referenced in other threads will not thread into the radiator. What have you guys found to work?

It should be a -6 straight thread but there is a catch. The factory fittings have that cone shaped washer, which pulls the trans cooler to the radiator end tank can creates a seal. If you do not use a fitting that does not have the cone shape washer the cooler will " push" into the end tank and engine coolant will pour onto the floor. Dont ask how I know.

on the radiator i used fittings from pure choice motorsports that clipped right into the stock factory fitting.
worked perfect.

No doubt. I was thoroughly confused for as second when it sprayed on the intake and down the radiator. Did you find a proper fitting to replace the factory cone shaped washer e clipped haydapter deal?

Really don't like the e clips but if its the only option guess it'll work. Looked on the site and didn't see em. Do you know the part number?

I have not. I did the old Tube nut and sleeve on the hard line. Not a fan of it. I heard Jiffy Tite was the oem supplier of the fittings but I havent found one with the washer.
