Automatic Transmission Control Module problems of the 2007 Jeep Cherokee

Purchased 2007 Jeep grand Cherokee overland 5. 7 hemi July 31, 2007. December 1, 2010 my wife was traveling on an interstate at 65 mph when the engine suddenly shut down. She managed to pull the car off the road, started the engine and drove home without any more issues. Dealership technician discovered p0884 code from the pcm. He could not find any problems. Car continued to stall numerous times at high speed and sometimes while stopped at a stop sign or red light. This problem started shortly after the engine spark plugs were changed. After numerous parts were changed at the dealership, with no results, the technician contacted an engineer from the Chrysler company. During an on site visit the engineer suspected there was an issue with the upper engine harness receiving an electrical induction from the engine coils causing the pcm to shut the engine down. The technician installed foil around the harness and wire tied the harness up off the cradles they lay in. Engine performed normal with no shut downs for several months. Decision was made to change the upper engine harness. Since the harness was changed my Jeep has stalled out four more times. The most recent stall occurred the last week of December 2012. This is an extremely dangerous situation to be traveling at interstate speed limits and your car stalls. Chrysler places drivers in a situation with a vehicle that is uncontrollable while traveling on an interstate with cars behind you. I started an on line thread in Jeep forum. Com concerning this issue. . Read more...
