I am planning on routing my lines for my tranny cooler this weekend and I need to know what size the outlets are on a turbo 400. I plan on running -6AN braided line but I still need to know what size adapter fitting I need. PLEASE HELP. Thank you

 

I think its 1/2 not positive though

 

1/4 npt, but don't crank 'em down too hard, it'll split the case.

^^^ that is the correct fitting. the trans threads are not tapered like a standard pipe thread, which is why you can crack the case with a 1/4 npt fitting.
