Trans cooler lines

[seattle73k5]

Does anybody know what size AN fittings to use for transmission cooler lines coming from the tranny? it is a 700r4 trans, the lines I have are jimmy rigged and are leaking so while I am at work tommorrow I figured I would make some new lines but I don't know the size needed.

thanks in advance.

they're not AN.. its flare.. its NPT coming out of the tranny.. 1/4 npt i believe.. it has an adapter coming out of that from npt to flare... i went steelbraided with AN so i got the 1/4 npt to #6 adapter and eliminated the factory adapter...

iirc correctly the flare size to the factory fitting is 5/16...
