Transmission cooler

I have a 2016 trd pro. How do I know if it has a trans cooler? Also, anyone use a plug in gauge to read trans temps while towing?

 

For 2010-2018, ATF cooler was built into the top of the AC condenser. Look for ATF cooling lines coming forward on the passenger side of the engine to the upper portion of the AC condenser. No tow package on 4.6L after 2013. If you have the tow package (and ATF cooler), your AC condenser will look like listing below, ATF connections second picture down:

Yes, many monitor ATF temps using several apps. Use Search feature.
