700r4 - ports?

I am putting a brand new 700r4 in my truck (truck is an International so didn't come with one). I plan on converting the inlet and outlet cooling ports to AN and using some hose fit for transmission fluid.

My question is... what size are the ports on the 700r4?

The plan is to do this:

Out: Trans. High Pressure -> Radiator port #1 -> Radiator Port #2 -> External Trans. cooler (top port) -> External Trans. Cooler (lower port) -> Trans. Return

Any input?

cooling the trans

I'd put the supply line on bottom and the return on top, that way you're sure that the cooler is going to fill before returning to the trans. which would give it more time in the cooler. It might pump fast enough to fill the cooler, but why chance it.

The Trans Case fittings are 1/4" NPST National Pipe Straight Thread not tapered thread. Tapered fittings can crack the case.

A proper operating trans has 25 - 60 psi in the cooler system and flows 3 - 6 quarts of oil per minute depending on engine RPM and throttle position. Filling the trans cooler is not a problem

Anyone know if thread sealant is a go or no go on these fittings? I pulled some old adapter fittings off and they looked bone dry so now I am questioning if I should put anything on.

Sealant should be no problem.
I've used it before with no ill effects.

I have used it, With no problems... The key is to make sure the tape doesn't get on the bottom of the Fittings.. As long as it can't get sucked into your trans.. It won't be a problem.. If it does get in the trans.. Then you will have a problem... I don't understand how some people can't put the tape on right..

Hi
Im no expert but normally don't like using Teflon tape on any hydraulics where there are valves involved prefer the liquid type thread sealer.
