Hi, does anyone know if our cars have a transmission cooler or are designed to have one bolt on? I have a 2015 gs350 f sport that I just installed a hitch to tow my motorcycle. It's fairly light duty but I want to be more informed.

Your towing experience is also welcomed.

Thanks,
Jason

 

Sub'd. interested to know as well

 

Just speculating but i think the GS-F has one; dont see why that cooler wouldn't "bolt-on" to the GS350, as it is the same transmission.

 

Just looked up the GS-F; it does have a transmission cooler:

Yes both GSF and RCF has it.

 

To answer your question, the GS350 (which you have) regulates the transmission temperature through a heat exchanger shared with engine coolant. So yes it has a cooler, but not the traditional air cooled transmission oil cooler you would see behind the bumper.
