I have a 2003 Dodge Ram 2500 Diesel that doesn't want to down shift out of Overdrive when I want to pass or pickup speed as when entering a high speed interstate highway, even if I floor the throttle. I am new to diesels so I do not know if this is normal. It does create a problem when I am towing my camper. To slow to gain speed. I beleave I have the 48RE transmission, is this normal? |

Takes a minute to shift into reverse. What should I do? |

| I have a 2001 Dodge Ram 1500 2WD automatic with 95,000 miles on it. About 8 months ago my gear selector, while it still worked, stopped locking in. All was fine until one day after sitting for a week, I backed out of my driveway, put it ingear and took off. Just as it was about to shift, it went right to neutral. Now all I have is park and reverse. 1 year prior to that I had to change the pan, gasket and fluid, all were replaced with MOPAR parts. Does anyone know where I should start ? | |

Had it rebuilt at 125,000mi. Now 149k. Didn't want to shift into 2. Had a speed sensor replaced. Drives ok for about 10 minutes, then wont shift into 3 untill the rpms go sky high. Then after a few minutes the O/D lite goes on. Am I doomed? |

It has 140k, never had a issue then all of a sudden it is having a problem getting out of 1st if on a grade, if i start out slow it will go through the gears just fine. Is there a simple fix or am I doomed.

Replying to: orman (Feb 07, 2009 10:03 am) Again, in RWD platforms (all trucks) there is a Rear Wheel Speed Sensor. This sensor supplies a signal to the PCM through the Controller Antilock Brake (CAB or Antilock Brake Controller). The PCM supplies the signal to operate the speedometer, among other functions. On to your problem. *If the Speedometer is not working, but the Odometer advances as the vehicle is driven, you have a defective Speedometer gauge or a break on the cluster circuit board. *On Chrysler systems if the Odometer or Trip Odometer is blank, you have an internal error on the instrument cluster assembly with the PCI data bus and the speedometer will not function. *If a "NO BUS" message is visible in the odometer, there is an internal problem on the cluster circuit board or there is no PCI data circuit between the cluster and the PCM. *If the Odometer readout is flashing repeatedly, the instrument cluster is not receiving a distance signal from the CAB. *If the circuit between the Rear Wheel Speed Sensor to the CAB is lost, the speedometer will not work, the odometer will not advance and the ABS lamp on the instrument cluster will be illuminated. Since I do not know what the state is of the odometer in this case, and you've already replaced the Rear Wheel Speed Sensor in the rear differential, I would suggest checking the rear wheel speed sensor circuit back to the CAB. On vehicles of your vintage corrosion at the rear wheel speed sensor terminals is a common problem, but I would check all of the connections at the CAB and PCM terminal connectors. If the odometer is working, you've probably got a bad speedo gauge. Regards, Dusty |
