explorer transmission cooler

Where is the best place to mount my tranny cooler? I got a cooler from an explorer and was trying to figure the best place to mount it. In the center of the rad? on the drivers side, pass side or perhaps lower on the crossmember? I had it in the center, but I just bought a JCR winch bumper and winch, so I didn't want to block too much air from the grill.

Thanks,
Chris

I did mine in front of the clutch fan since its the constantly flowing fan

Yeah, I think I'm going to leave it where it is. It's just off the center on the passenger side in front of the clutch fan. Now I have to fix a leak in the steering box where the steering shaft goes in.
