In my opinion get a proper engine oil cooler.
Transmissions use a much more "crude" oil to lubricate and have different properties and cooling requirements than engines.Also there is another issue with flow rate decrease due to the cooler it self. So u dont want a restrictive cooler for your engine oil because of the mechanical oil pump (more load on the pump=more hp loss)
Dont want to put u off trying something different, but give a more complete answer...
