Default Transmission cooling line fitting size?

I’m gonna run AN fittings and SS lines for my cooling lines, was wondering if someone here knew what size and type the fittings are on the transmission?

I used 5/16 brake line to plumb my 700r4 if that helps.

I have a 700R4. The case has brass reducers down to 3/8th. I removed the reducers from the tranny and installed 1/2 ID S-Braided lines going to my B&M cooler which was also 1/2 inch.

Gkull did you use the cooler in the radiator along with the external cooler? I looked at the brass fitting but did not think of removing them. I’ll take them out tonight and see what size hole is in the case. Do you think the AN fittings with O-rings will work on the case?

I don't use the radiator. I have the biggest B&M unit that I got from Summit Racing. I had a place make custom hoses at a hydrolic shop. The ends swivle.

I just yanked at the stock tubing and ran mine along the innner frame rails.

This is the B&M tranny cooler U use with my 1/2 inch inner diameter teflon SS hoses made up by a hydraulic shop. I bought mine from Summit Racing.
