Anyone know the fitting size for the transmission cooling lines at the radiator? Is it a flared fitting? NPT? I want to install a cooler but I need to know what adapters to get (flared to barbed, NPT to barbed, or what?) Any links to a site with that kind of info would be of great help.

 

3/8" inverted flare long throat. I was unable to find these fittings when I installed mine a year ago so just cut the line and spliced with hose. However, in the last week I was surfing for a cooler for my van and found a site that had similar fittings. See below. You'll have to contact them to see if they have 3/8".

Might want to check Summit racing too.

 

Thanks, Tiger! You da man!

 

Just finished some research and made some measurements on the transmission line fitting for my radiator (2001 V6), it has 5/8" O.D. threads on the male fitting. The fittings are, as Tiger said, an inverted flare; however they are 5/8-18 thread (standard for 3/8" tubes). See the links below. bulkparts.com sells the Hayden adapters (#T395). Derale also makes them (PN 13025). And, as Tiger said, drawtite-hitches.com has them (PN 6442).

This is probably more information than anyone needed to know, but I'm making this post so I can find the info later, myself.

Sorry, that was a brain-fart on my part. I was thinking about the tube diameter. You are correct.
