I'm considering adding and after market oil cooler to my N54. As far as I know my existing oil cooler is in decent shape, so I'm thinking that I want to repurpose it as a transmission cooler. I can run a solvent cleaner through it and then blow it all out with a bunch of air. Then run a at or so of ATF through it to make sure it's clean.

I believe the trans cooler fitting is just a flair/barb so I can cut off the oil fittings and flair them.

The only issue I can think of it pressure difference. Can anyone comment on this? Or any other concerns I'm missing?

Trans fittings are quick disconnects atleast where it connects to the trans heat exchanger

Is there anything that would keep me from snipping off the disconnects and hose clamping them on?

I don't see why u couldn't do that, I personally wouldn't

Does anyone know what kind of pressure an oil cooler vs trans cooler?

I've ran a 25 row setrab oil cooler for my trans cooler for last 1.5 years with no issues. Cools very well.

This is interesting. I'm looking for a trans cooler rn and only thing holding me back is all the varying ranges of prices. If people are putting rando heatsinks in for coolers I feel like I'll be fine using anything. Might even do what OP is doing lol.

What about the T-stat that ensures the proper heat range of the trans oil? If you just hook up "oil cooler" I am certain that during the cold days the operational range of oil would be too low (esp. during high speeds/low load), so wear, impact on mpg?

Yes, I run 165 degree thermostat and have eliminated the auto heat exchanger.

You can just cut the existing lines and and barbed fittings with hose clamps. 2 clamps on each side of you want to play it safe.
I would also run a thermostat between the stock lines and the new cooler to ensure your reach operating temp before any additional cooling is required.

Good looking out! Gotta get it back on the road before I mod anything else
