The NAG1 is a Mercedes-Benz sourced five-speed automatic, and it does not take the same ATF+4 that the rest of the Chrysler lineup uses. Putting the wrong fluid in one of these is a well known way to create harsh shifts and torque converter shudder, so the fluid specification matters more here than on almost any other Chrysler application. This is the genuine Mopar fluid built to the correct spec.
