Most likely your radiator trans cooler takes a 5/16" HARD LINE... with a 45* double inverted flare... so if you're going to try to convert that to a -6 AN - you're going to have to figure out what it SHOULD take and then try to find a conversion fitting.

Thanks. Yes, 5/16" lines are what I have and they bolt right up, so this isn't a one-off custom setup. I know there is more than one person that has done this before.

I think I found the fitting. I'll give them a call tomorrow. Thanks a bunch.

Vegas, the B&M cooler is 1/2" NPT. I was just uncertain if the fittings I had fit because I was only able to engage 3 threads by hand. Seems that is sufficient and with a wrench and thread lube it will engage more.

Thanks for the help guys.

Actually, this brings to light one more question. What fitting to attach the an hose to the trans 5/16" cooler line?

that's only if you're using hard line. If you use A/N line they make a 5/16" inverted flare to male #6AN adapter.

Yeah, that's so I can attach the line to the hard lines I have run

If you were in San Diego I would sugest you stop by my hardware store and we have almost every plumbing fitting to test fit.

It looks like you got it sorted.

A NPT fitting will thread in about 3 turns before it starts to tighten due to the tapered threads.

If the radiator is set up for 5/16 hard lines and that's what you've run then you don't need any adapter AN fittings. Simply cut the tubing to length, add the inverted flare nut (before you flare the tubing) and flare the end of the hard line and you're done. If you don't have the 45 degree flare tool you can borrow or rent one. I'd prefer that over a compression adapter fitting, but either will work.

Thanks Jody...Although, I gotta quit hanging out over here with you guys. I just called up Pure Choice and they put a $80 dollar hole in my pocket on top of the $100 dollar hole I put in it yesterday ordering fittings ON top of the already, who knows, how much I already have in fittings!!!!

Thanks a bunch though guys!! I got me some new fittings. Now I need to go get some hair plugs to replace all the hair I pulled out trying to figure out all these darn fittings.
