C4 Transmission fluid fittings

I installed a new trans cooler in my rig and used 6AN lines and fittings. Now I need to get two 6AN to ? fittings to hook the lines up to the transmission. It looks like a straight thread. Does anyone know the size/specs of those buggers! Thanks

I didn't know the C4s has 1/8 NPT fittings? I thought they were straight threads, not tapered. I do know that powerglides are 1/8 NPT for sure.

I believe the threads are 1/8-27. The same as 1/8 NPT, but without the taper.

Thanks guys, now i'm looking for a 6AN to 1/8 adapter. Earls AN only goes down to 7/16 as far as I can tell. Where I live I have to mail order, so does anyone know a good AN fitting site?

Thanks for the input on that. I saw that one and it is NPT(Pipe thread). I am looking for 6AN to 1/8 27 straight thread for my C4 cooler line ports. Earls does have some, but not that size. They call them port adapters. Earls server is down til the owners come back on 1 July, so I will wait and see if they can track it down. Thanks for the post.

My Bronco's C4 has a rubber o-ring on the fitting. Should I just add an oring to any 1/8-27 fitting I buy?

The problem with just adding an o-ring to any normal pipe thread fitting is there is no groove for the o-ring, like there normally is in all straight thread fittings..

what i did is slightly run an 1/8 27 tap into my case just enuff to slightly taper the outer threads...did this nice and slow, checking every so often with a 1/8 pipe fitting..and i have read of others doing this also.
I also found some 1/8 pipe to #5 JIC steel hydraulic fittings..and they just so happen to have a groove in them to accomadate the o-ring....now what I dont know is how
JIC compares to an AN style fitting???

I took an easy way out to fix this problem... The JIC fitting must be kept, and they have a 5/16 inverted flare fitting... Go to the autoparts store, get a short piece of 5/16 steel tubing with the correct flair and nut to fit the JIC fitting. Then you have to find a steel -06 an fitting, the one I used had an NPT thread on one side and AN on the other, I got it from a caterpiller (the heavey equipment guys) dealer. Cut the tubing, with about 3 inches of line but keep the inverted flair fitting and nut on one side. Clean the cut area to get get the galvanized coating off, and debur. Take the AN fitting (adapter) and drill out the NPT end so that cut side of the steel tubing slips in about 1/4 of an inch. Then braze it up, and you have your adapter.
