Transtar highlights its line of coolers and warmers for Nissan vehicles. Models covered are the 2010-2012 Nissan Ventra and the 2013-2018 Nissan Sentra.
According to Transtar, the ideal operating temperature for the transmission and fluid is between 160 and 200 degrees Fahrenheit. Transmission fluid cannot be over-cooled, so Transtar suggests adding an aftermarket cooler as factory coolers can be inadequate for towing applications.
