TranstarCooler Line Fitting, M18 x 1.5, With Slim Line

Protect your reputation, and your customers’ transmissions, by installing a transmission cooler during a rebuild. The ideal operating temperature for the transmission and fluid is between 160 and 200 degrees Fahrenheit. Transmission fluid cannot be over-cooled, so adding an aftermarket cooler would be a good idea as factory coolers can be inadequate for towing applications.
