Oil and Trans Cooler Fittings

[BGKYK5]

I am planning on replacing the stock hard lines for the oil cooler and trans cooler (truck in sig). Anybody know what the fittings at the trans (1/4" NPT male?) and at the adapter above the oil filter are?

Also the fittings at the oil cooler (not gonna use the stock ATF cooler in the rad).

TIA

1/4 NPT will work with sealant. I feel these are a better option. I have a custom set on my TH400, but I also have a set of the Sweet Performance adapters to put on if ever work on the transmission. For now my custom set seems to work.
As for the oil cooler, it sounds like you plan to put on an aftermarket unit which there is a wide variety of coolers that take different fittings. Get the cooler first so you can find out which fittings to get.

Thanks, those look great for the trans.

I actually have two stock oil coolers. I plan to use one for oil and the other for ATF.

Good luck finding fittings for the stock oil cooler. It takes a special fitting that i've not been able to find.

x2 tried doing it with my CC. No dice

Hmmm, cut the hard line and put a compression fitting on it?

I used 14" NPT to -6AN on my trans, they work well.

I would use the rad cooler in line with an aux trans cooler. The transmission oil depends on engine heat to warm it up. I found this out the hard way.

It doesn't get very cold here, so I'm not too worried about cold/thick ATF.

I'm in South Texas but a freezing spell got my transmission. That's when I learned.

It is not my DD, but I'll keep that in mind - 'spose it could't hurt.

Anybody know what fittings the oil filter sandwich adapter uses?

3/8" pipe?

Or is it 1/2"?
