Can an AC Installed make the engine run hotter than before?

I don't think that the radiator shops/vendors will say for positive that they would take it back if it doesn't work.

Think I am going to install a tranny cooler and get that out of the radiator. Every 20 degrees cooler a tranny can run will make it survive longer.

Who knows, maybe that might lower it 3-5 degrees too.

Thanks everyone for the replies and suggestions. Much appreciated.

If you add a tranny cooler do not route it solely through that. They are auxiliary coolers for a reason. Adding one is a great idea, but also keep the lines running through the heat exchanger in the radiator as liquid dissipates heat more efficiently than air.
