Frozen Ram Needs an Update
This bulletin applies to 2012 Dodge Ram 1500, 2500 and 3500 cab chassis trucks built before Nov. 15, 2011, and equipped with a 4-speed 42RLE or 6-speed 65RFE or 6-speed 66RFE automatic transmission.
The MIL may illuminate, with DTC P0441 stored (EVAP purge system performance). The transmission light and/or transmission cooler freeze-up may be involved as well. This condition will typically occur when temperatures are below minus 10 degrees Fahrenheit.
The technician may also find DTC P0218 set (transmission high temperature operation activated). Updating the software will correct these conditions. Use software release 12.01 or higher.
