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.

For the benefit of others that may be reading this post, for Chrysler-built rear wheel drive vehicles there are speed sensors in the transmission (one in RE & RH trannies; two in RFE trannies) that send signal(s) to the Power Train Control (PCM) and Transmission Control Modules (TCM). These signals are used in determining various internal control functions in the transmission and performance operation.
 
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

46re trouble by xscooba

1996 dodge ram 1500, 46re tranny (189,000 miles). problems shifting from 1-2. usually shifts late (over 3,000 rpm's) or i can shift to neutral and back to drive then it will shift. governor pressure solenoid and transducer both new. the two solenoids beside them test fine.
 
i'm trying to remove the valve body to check it out, but tranny is still in truck and i can't figure out how to disconnect throttle linkage to allow valve body to drop out. any help would be appreciated.

Check the operation of the Transmission Throttle Valve and cable at both ends for binding. The Throttle Valve Lever on the tranny should return all the way when the Throttle Valve in the Throttlebody on the engine is in the idle position. Check for a missing or broken return spring.
 
Are you having trouble removing park rod or the manual lever? There's an E-clip on the end of the park rod. You need to rotate the valve body in order to release the rod. The manual lever shaft simply pulls through the case.

there is a linkage on the outside of tranny above throttle body where the return spring is and it holds up the valve body when trying to remove.

1997 Trans stall by stemper57301

Hello,
  I have a 1997 dodge ram 1500 with the 360 in it. I'm not sure of the trans. 46 or 47. My problem is that once in a while, mainly when its cold or wet, it will almost seem like it's slipping. Also along with this problem it stalls in drive and shakes like it wants to die. If I shift into 2nd it works no problems. There is a check engine code for low output speed sensor, I replaced the output speed sensor on the trans and it did nothing.Light is still there Any help or ideas are greatly appreciated.
Thanks

transmission dodge ram 1500 by jeriz

my husband has a 1500 dge ram 1998 p/u. It is in the trans shop for repair. They said that the transmission cooler failed and it let transmission fluid into the radiator and anti freeze into the transmission - is this possible. They are saying to repair could cost up to 2,900.00. Does this seem right? Once the truck gets hot it won't go into gear except for reverse. Once it cools down it does go into gear. Thanks,
