2002 ram 2500 extended cab 25.9 l gas auto 4x4 had problem cold would stall could drive with 2 feet keep it from stalling pulled trans went thru it found nothing but a 2/3 accumulator spring broken . replaced all selonoids

    Check your transmission cooler for a restriction. We usually end up eliminating the factory cooler and installing an external unit.

    http://www.atra.com/ If its not being commanded on, then it is falsely hydraulically applying. You might have a bad valve body and need it repaired/rebuilt.
