That's precisely how I did mine. Deliberately purchased a "manual" radiator, because I'd already had an external cooler fitted.

There's a caveat to not having the transmission cooler inside the radiator. On cold mornings, you have to drive further before the transmission comes up to temperature and behaves "normally" - mine won't engage the torque converter clutch until the coolant temp (only related to transmission temp as an indication of having driven the vehicle for a certain amount of time) goes over 60C.

Otherwise, it's a good choice.

I don't know what brand of cooler I have specifically, I just paid a mechanic to do it (and ended up with two, the oil flows through one then the other then back to the transmission). They're mounted in front of the intercooler, the hosing just runs straight from the gearbox up to the coolers and back. No extra fans, nothing. Rather simple really, and no more concern about gearbox contamination by the engine coolant.

Just be sure to remind anyone that works on the system that you have a separate transmission cooling system. I didn't, and the idiot that I had work on my gearbox cross-connected the thing and cause my gearbox to fill with coolant. There was so much damage in just a week of driving that I had to replace the gearbox.

And yes, we also had to do a special intensive flushing of the coolant system as well. Lesson learned - make sure they pay attention and don't stuff it up!
