Greetings, I have a ’05 CRD with 58k. I have two issues. First driving in a straight line at a consistent speed, about 65mph the car will suddenly shift out of overdrive to a lower gear. This makes the car slow down rapidly as the engine rpm’s jump up. After a couple of seconds the car will shift back to overdrive and drive as though nothing happened. The second issue, which is new, seems to be a slipping transmission. The engine runs fine but when any power is applied there’s a whooshing noise, the rpms go up while the car makes a “soft jerk”. Has any one else experienced these problems? I’m totally disgusted with three jeep dealers in my area and the car is out of warranty. Dave |

Replying to: doh4 (Apr 11, 2009 8:36 pm) I have had this happen 3 times. All 3 times it was raining or very high humidity and a ScanGauge was connected. I stopped using the ScanGuage except for brief readings and it has not happened since - even in heavy rain.  Last event was over 30,000 miles ago.

Replying to: doh4 (Apr 11, 2009 8:36 pm) In the logic sequence of the ECU, erratic down shifting can occur when: - the temperature sensing of the transmission oil suddenly becomes low (too cold), - the engine load sensing changes (accelerator pedal sensor), - the EGR air control valve mechanically over corrects it's mixture, reducing engine power (excessive play in the assembly), - one of the Lambda sensors is defective and forces the EGR to 'choke' the engine. The EGR should come into action when at consistent speed with a warm engine and low load condition. The overdrive comes into play when the engine coolant and transmission fluid are up to temperature. Last but not least is the fluid level and pressure in the converter.
