Ram 3500 6-cyl Diesel

  • Automatic transmission
  • 1,200 miles


2005 Dodge Ram 3500 with cummins turbo diesel. This particular model has a "tow-haul" mode that will not lock the transmission out of overdrive. If you are descending a hill and you so much as touch the accelerator then the truck automatically shifts into overdrive and sends you speeding down the hill. The "tow-haul" mode also downshifts the transmission into second gear at 50+ mph and that can also spell disaster while descending a hill on a cold day. My fist experience with this was earlier in the week while traveling to Tennessee. We had to tow our 8000 lb race trailer over mt. Eagle and encountered both situations while descending the hill. This is an extremely dangerous problem that needs to be addressed immediately. The 2004 model and the new 2006 models both have an overdrive "lockout" to keep this from happening and I'm not sure why it was neglected on the 2005 models.

Ram 3500 4WD 6-cyl Diesel

  • Automatic transmission
  • 1,500 miles
Dodge represents the 3500 Ram I purchased to be a heavy duty tow vehicle capable of safely towing nearly 16000 lbs. Upon my purchase I quickly discovered that they have removed the basic overdrive lock out feature found on most if not all vehicles in this class of automobile. The computer program and transmission controls will command this vehicle into overdrive regardless of terrain or load being towed or carried at the time. Bottom line if you touch the gas while going down a grade pulling a 16000 lb trailer you will find yourself in overdrive lacking any way to bring the vehicle under control other than the brakes. Plenty of complaints are available to be see at www.dieseltruckresource.com this forum has several postings concerning 2005 tow haul mode. The discussions can be found in the 3rd generation drivetrain discussion board.

  • Automatic transmission

Dt when putting the vehicle into park it will jump into reverse. On one occasion the vehicle rolled away, and over top on the consumer, across a street, and hit a parked vehicle. Consumer had cuts and bruises on his knees from avoiding the rolling vehicle. On other occasions, could not get the key out of the ignition when it shifted into park. Did this intermittently. This has happened a dozen times. This happened around January 15, 2005. Had not contacted the dealer. An engineering firm was sending someone to look at vehicle.

Ram 3500 4WD 6-cyl Diesel

  • Automatic transmission
  • 1,000 miles


Dodge Ram with cummins diesel engine. The consumer was unable to decelerate when letting off of the throttle. Had one minor fender bender, and a near miss as a result of feeling as though the motor was still pulling. No repairs, but has been to dealer twice. Contacted Chrysler, who stated this was programmed into the computer to do this due to the automatic transmission which magnified the problem. Had no plans to change this design. Currently this is still a problem.
