car   Automatic Transmission Control Module problem 1
Failure Date: 03/20/2009

2004 Jeep Liberty sport. On March 20, 2009 while driving, the auto transmission slipped out of gear, would not shift out of 1st gear. On March 24th, Liberty returned to us. Dealer charged $500 to replace wiring attached to pcm, stating they were worn out and not covered under warranty. On April 24th the same problem occurred while driving on the interstate in connecticut, the Liberty abruptly downshifted from 4th to 1st gear nearly causing us to be struck by trailing vehicles, and would not go into any other driving gear. Jeep dealer in greenwich, CT said they suspected the tranny was worn but could not undertake the repair. We cancelled our trip and brought it to a local dealer on April 25th, bad pcm diagnosed, replaced. Warranty covered. Received Jeep back on 5/1/09. Later the same day the problem occurred again while driving on highway. Brought it back to same dealer. Pcm replaced again we're told. Liberty returned to us on 5/6/09. On 6/9/09 while driving on the highway the Jeep shut down completely once again an accident was narrowly avoided. Towed to a different local dealer. Bad pcm again diagnosed. Part had to be ordered. Liberty finally returned to us on 7/2/09. On 7/9/09 while driving on local road, the transmission slipped again and would not shift out of 1st gear. We brought it back to the dealer who did last repair. As of today it remains there. The check engine light came on in each instance at the exact moment the problem occurred.
