Two problems related to automatic transmission torque converter have been reported for the 2007 Jeep Wrangler. The most recently reported issues are listed below.
While driving on paved roads at speeds of 35 mph or less in a local park, a loud chime began to sound with no corresponding indicator light. I pulled over and shut the engine off, waited a few seconds, restarted the engine, the chime was not sounding, so I drove home. Once on the highway, the torque converter would not lock up properly and continued to slip for several miles until normal operation resumed. After checking everything once home, it appears that the chime was indicating the transmission was overheating, explaining the malfunction of the torque converter. I have read of others having similar experiences. I need to stress that this over heating occurred under normal operating conditions. Updated 05/24/jb.
Whilst driving at 65mph the vehicle began to vibrate violently and become uncontrollable. Almost like it was bouncing from tire to tire. Came to a stop and turned off the engine. Took the vehicle to the dealership and was told they have recognized the problem and fixed it. I was told it was a problem with the torque converter. This occurred around 14000 miles. Since it was "fixed" I have had problems with the transmission and went back to the dealership who could not find a problem. The initial problem occurred again at around 16,000 miles the vehicle becomes uncontrollable due to the violent shaking. This is a serious safety issue.
