transmission cooler line fittings

Hi
I'm installing one of those finned aluminum frame mounted tranny coolers. I am going to run hose from the tranny to the cooler and back (no hard line). My tranny had the fittings in it for a hard line to connect to ,I took them out and put in npt fittings with hose barb ends,I sealed them with yellow teflon tape . The thing is the old fittings had a washer-gasket that bottomed out when screwed in my new fittings don't. Will I have a leak? Is there any pressure on them lines? Or will it be OK ?
Thanks

I had that same question when I did mine. TH350? I put NPT AN fittings, with a little pipe tape, snugged them up and was fine.

You need 5/16 inverted flare to barbed ,look around the carburetor isle. Leave the fittings in the case ,there're there so you don't crack the case with tapered thread fittings .

This is also what I would suggest to avoid crack in the case.

Thread a proper fitting into the OEM cooler line fitting.

OK
I'll have to go look around,I already threaded the npt barbed fittings in I hope I didn't screw something up I was doing what the guy at a local parts store told me to do ,but they don't seem to tighten snug, thats why I was asking if it was right. The fittings that were in the tranny that the original tubing screws into I don't think npt screws into them,or do they?

Now I'm really confused!!(or just stupid) I have 3/8 hose and the fittings on the cooler are 3/8 barb,but not sure what size inverted flare fitting I need ,and would I get a male and screw it into the existing tranny fitting,or would it screw directly into the tranny? If u could look at the site u recomended and tell me the part number I would be eternally in your debt.
Thank You
Gary
