My wifes 04 WJ has 4.0 liter and 2WD 42re transmission. No trans cooler in the radiator, is running aftermarket cooler in the grill only, looks around 11x7 cheap tub and fin cooler. The hoses are starting to look rough/cracked so I need to at least replaced the cooler lines to the cooler, but was thinkin of replacing the cooler while I was there with a more efficient staked plate cooler of at least the same size, and possibly larger. But, if I put an 11x11x.75 cooler in there, will it block so much airflow that I risk the engine running hotter?

Next question: Right now my cooler is ziptied to the condenser and radiator with those cheesy zip thingies that come with the coolers. I want to mount the new cooler to the radiator support in front of the condensor but, I may end up an inch or more in front of the condensor. Will a large gap between the trans cooler and the condensor cause a problem? I'm afraid if the trans cooler is too far forward, the fan won't draw air thru it and it won't cool properly.
