This bulletin applies to 2012 Dodge Ram 1500 trucks equipped with the 5.7L engine, and either the 4-speed 42RLE, 6-speed 65RFE or 6-speed 66RFE automatic transmission. The MIL may be on, and/or the transmission light and/or the transmission cooler may be frozen.

DTC P0441 (EVAP purge system performance) may be stored. If the truck is equipped with the 6-speed transmission and the transmission cooler is frozen-up, this condition will typically occur when temperatures are below -10 degrees Fahrenheit. The technician may also find DTC P0218 (transmission high temperature operation activation has been set, active or stored).

Updating the software with release 12.01 or higher will correct these conditions.
