Engine and Auto tranny oil cooler

I connected to my tranny oil using Banjo Bolt M18x1.5 with 12mm Hose Barb Fittings here. You might try to find an AN fitting with M18x1.5 threads, if you have the F35 transmission. What engine and transmission do you have?

I don't recognize your transmission, as it isn't the same as mine. My donor car was a 2006 Cobalt with the supercharged engine. Do you know what your donor car was?

You need to add that info and the type goblin to your signature, so when you are asking a question we know what setup we are dealing with.

That’s a 4t40 or 4t45 pretty much the same either way. I would probably use the original line set and modify it with trans cooler hose. Don’t use 3/8” fuel line for trans cooler it won’t last.

I have used PTFE hose which will do exactly what you’re looking for and there’s a compression type fitting to adapt metal line to AN. Hotrod fuel hose is where I got them from.

What makes you think you need a cooler on either one? My oil temp at the drainplug is lower than I would like, if the temperature at that point is indicative of what the overall oil temp is. I only see about 170 when the temp is in the upper 90's and climbing a long grade.

Transmissions always last longer the cooler they are. Engine oil cooler maybe not but a trans cooler I wouldn’t be without.
Up to a point, but is (random #'s) 150 degrees worth the complexity over 165. Plus, possible pressure changes. And a lot of time the coolers people add don't actually do much because of them being too small or lack of air flow.

My auto tranny gets above 200F on long rides. I have added a small passive cooler (5" x 7") off the auto lines and used barbed fittings and dual band clamps to secure it. Have to say without a fan, it doesn't do much.
