My 2005 dodge dakota SLT, 2wd, with a 545RFE RWD transmission has an issue we haven't been able to resolve. Sometimes, when you come to a stop or start up from a stop, she will stumble the check engine light comes on and then will not shift out of second. If you stop and turn the engine off and put in park, when you restart her, although the check engine light stays on, she shifts fine and may be fine for a while before she does it again. Transmission Valve Body and shifting solenoid have been changed along with both filters and fluid. Anyone have any idea what it wrong? She has 131,000 miles on her. Thanks
