Three problems related to automatic transmission have been reported for the 2007 Dodge Ram 1500. The most recently reported issues are listed below.
I put the vehicle in to reverse, in which it shows on the dash, then when I start backing up, it slips out of reverse and into neutral, in which nothing shows on the cluster of what gear it is in.
Truck popped out of reverse on several occasions. TSB on this. Brought to dealer - upgraded software. Also reported problems where it did not shift into second gear on cold start - had to coast for several hundred feet then hard shift. Dealer could not replicate. At 40,000 miles the transmission had to be rebuilt after loud clunk and then no power when starting out. Check engine light came on. Dealer said until check engine light comes on it was impossible for them to diagnose the transmission problem.
I was exiting a parking lot making a right hand turn from a dead stop. I gradually pressed the accelerator when without warning the vehicle began to accelerate uncontrollably. I pressed the brake pedal as hard as possible, however the power of the motor was too much for the brakes to over come. The front brakes locked up and I was no longer able to steer the vehicle. During this event I was baffled, it took a minute to grasp the fact that truck was accelerating on its own. The vehicle crashed into a guard rail at approximately 15-20 mph where it continued to accelerate until I turned off the ignition. I contacted Chrysler who came out and towed the vehicle to their shop. I am currently waiting a response from the manufacturer.
