...Denny I'm confused again! I just noticed you said the trans cooler fittings for a turbo 400 should be 1/4" fittings? And the fittings I have measure 1/2". So I subtract 1/4" from the 1/2" & this means my fittings are 1/4"? Correct? {cuz I thought someone said the fitting that I showed in my picture was a 3/8" fitting?}... whew, I hate fittings! Thanks again, Bill
