What size thread in radiator

[TURNA]

What size is the thread in the radiator transmission cooler?

I want to get adapters to screw into the radiator and have an AN fitting on the other end.

And then the same for the transmission lines end

I want to install a cooler and make it look pretty.

I bought these for my 400 trans since you need a straight thread and not tapered for the trans.
I also run 8AN for my trans lines instead of the more common 6AN.

These go into the trans. I need into the radiator

pontiacgp already posted what you need for the radiator.

I thought by this you meant fittings for the trans also.

So you want to add an auxiliary trans cooler to an existing set up that uses a built in trans cooler and use AN lines to do this?

I like the AN fittings in the transmission as well since it is easier to disconnect those fittings compared to removing the stock fittings from the trasmission

Yep bought a new radiator fan setup and going to run an external trans cooler with it.

I like the AN fittings for ease of use like pontiacgp said

So this fitting is good for the radiator correct??
