Dodge Ram Transmission Problems

    To pull codes, it's an ignition key cycle.

    In quick succession - On (not Start)-Off (not Lock)-On-Off-On
    Then watch your odometer display. Any codes will show there (P follow by a 4 digit number).

    i have a 2001 ram1500 5.9v8 auto. i replaced the heater core yesterday and today after i put the dash back on and stated it up and put it in gear to back out of the garage, but it was a no go, doesnt move in any gear and when i try to put it back into park, it makes a grinding sound, any thoughts?
  • did you get it figured out if so what was it my 98 doesnt do low or reverse it used to only go in low and reverse electrical?
  • no i haven't figured it out. i've been workin too much overtime and goin to school. thank god for the wifes car, i asked around and im gonna tinker with the electrical this weekend, i need to double check all the connections and see if i missed a connector or didnt push one in all the way. ill let you know by sunday.
  • I had the same problem. Solved it by disconnecting The negative battery cables for one minute to reset the computer and installing a 30 dollar APPS noise isolator from BD Diesel.It only took 5 min and I'm not a tech
  • I have 2002 Dodge 2500 Diesel. For the past 2 years the transmission will shift back and forth when it is in the last gear. At times I disconnected the neg battery cables and reset the TPS. Sometimes this lasted for 2 months. The problem always comes back. Recently I replaced the TPS. After 2 weeks the problem is back but not as bad. Does any one have any ideas?
  • 3-4 shift sensor??
    i recently had similar a problem , wouldn't shift from 3 to 4 then erratic shifting... i replaced the governor sensor, governor plate and the 3-4 shift sensor. not cheap.. so i went to a dead trans at the wreckers... took out the parts i wanted... works like a charm. i replaced all three parts as i was told by trans shop that it SHOULD be any one of those parts.. i know, i know.. used parts in a trans... but i had to !!!!
  • I have a 1996 dodge ram pickup 1500 5.2 v8 and my transission will only go into first gear and will only drive 30 miles an hour so i am trying to figure out what is wrong with it. Anyone have any ideas?
  • i have a 98' 5.9 cummins and i need to replace the pedal position sensor its a tough part to get ahold of but i also need to know where to look for it on the truck (this needs to be done ASAP!!! and i don't have a manuel) PLEASE HELP!!!
  • could be that the rooster is stuck past the parking paul in the tranny, as for the codes any P1's are dealer codes
  • 30 mph is fine for first gear.... you might want to drive slower if you have to drive it at all..
    my best guess is the 1-2 shift sensor.. or governor sensor... i had a 3-4 shift sensor problem... would only go 1st and 2nd gears no shift to third... it's in this forum somewhere.
    i went with used parts!!! lol, i was BROKE... and it still shifts like new....
  • from another forum i was told....
    try a good auto wreckers, these things go without reason both new and used....

    It is on the part that the throttle cable hooks to on the engine.
  • 04 2500 diesel with 48re tranny starts out in 2nd gear revs to 3000rpm then shifts into 3rd but never shifts out of third hooked scan tool up does not show any codes i was told gov press. sensor wound't that show a code.plese help going to move soon
  • my 2002 ram 1500 4.7 is still stuck in limp mode, even after i replaced the solonoid pack, filter and fluid, and the tcm. the only codes that show up are those caused by the solonoid pack. what else could it possibly be?
  • i have a 96 ram 1500 club cab auto 5.2
    THE ISSUE: after running for a little while the transmission starts to slip out of OD, and the tranny feels like its in nutral and the engine revs way up. then when i put the rpm down it sometimes catches back into gear, there is also a wierd grinding sound coming from the tranny while driving which increases in sound with speed. sound stops when i turn OD off? the worst day ever with the truck happened yesterday after i drove like 20 miles straight, it slipped so bad i couldnt even take off from a stop as if it was in nuetral. Ive heard this is because of the tranny cooler lines, also some valve and sensor? anyone have the same issue and know of a solution. if not im just gonna get a used tranny with 100k on it for $400
  • I own a 2001 Dodge Ram 1500 pickup, 5.2L. Trans shifts are erratic and sometimes rough. It seems to shift better when I keep the RPMs higher in city traffic. Fluid and filter have been changed. I also have a trouble code P0455 (evap emission control system gross leak detected). Any connection between the two? Any thoughts? Truck otherwise runs good.
  • I have a 98 ram 3500 auto. It was shifting fine but the trans has 190k on it and it had been 65k since the last filter change. I replaced the filter and drove about 45 miles. Everything worked fine. When i drove the truck next it started in third gear and wouldn't shift at all. I can downshift into second manually but not first. This is my only truck and i need to get to school. Any ideas will be much apreaceated. Thanks, Daniel.
  • This happen to me also on my '03 truck. It happened off and on for long time. I was told an error is seen in the TCM and it goes into safety mode. I was told to check my ground wire. I had a 5+ year old battery and the ground cable was not so good. I replaced both and have not had an issue since. Maybe during fluid changed something happen to the wire harness.
  • i have the replacement bolt in for about a year and now it has came off i pulled everything off and tightened it back up and spot welded it there and it came off less then 4 hrs what should i try now
    98 dodge ram 3500 duelly
  • 2005 dodge 2500 disel 109,000miles auto trans will not shift out of low gear. rev, park , neu is all good and snaps into low like normal. problem came out of no where. trans has not been serviced. any ideas?
  • i would be willing to bet that it is your 1-2 shift sensor, could be the governor sensor but i doubt it...

    I am looking at buying a Dodge 2006 2500 diesel. I had a GMC 2500 gas and when you went uphill with a load it would downshift violently and go to 4,000 rms. I was wondering if any body knows if the dodges have any problems like this on there auto trans (48re i think). I would get a manual trans but they are harder to find. Please help, thanks.

    My truck has been running great until recently when I hit a cow and had to replace the cooler, radiator and air conditioning. It ran great again for a week. Two days ago, I replaced the fuel pump and today there was a loud bang when I stopped at a light, then it only ran in 2nd gear and reverse. When I started going up a hill, I lost all forward gears and had only the reverse gear. I replaced the transmission fluid with ATF-3. I'm stilling having the same problem. Any suggestions as to what I should try next? I'm at a loss and appreciate any help.
  • Wha'd you hit there Hoss, an Angus, Holstein or Jersey?
  • I have a 2006 Dodge Mega Cab 4x4 Diesel w/auto tranny. It surges from 1st to 2nd gear if you are driving slow, but hardly notice if you put your foot into it. Also, it is slow to shift from 3-4 and worse from 5-6 when pulling a trailer. Do not notice it much unless pulling. It will rev to 3000 rpm's before it shifts. I have had multiple transmission shops and dealers look at it and most find no codes on the computer but have replaced the following: Pressure switch and pressure regulator, replaced solenoids and sensor adjust bands, Gov SOL and Gov sensor, Prndl switch and connector, serviced with new filter and fluid twice. All this and still having the same problem. Took it back to the same dealer as last time and now they are saying it needs a Throttle Valve Actuator, Govenor Duty Cycle Solenoid, Pressure Transducer, Adjust Both Bands and update the computer with a new service bulletin that recently came out that is suppose to help shift quality.
    If anybody has any suggestions or have had this problem and can help, please let me know.

    I have a2005 Ram 3500 diesel with the 48RE and have not experienced any violent downshifting uphill. Usually before I climb a notable grade, I'll activate Tow/Haul which delays upshifting to keep the engine in a good power spot. And with the diesel, you won't go beyond 3200 rpm (in-gear redline).

    If you have a 2006 diesel, you only have a 4-speed automatic (48RE), so there wouldn't be a 5-6 shift. The 6-speed automatic wasn't introduced until January of 2007 with the new 6.7 liter Cummins engine.

    If all the mechanicals check out and there's no sign of overheating fluid, delayed shifts are usually a computer problem of some sort. And for the non-dealer shops that worked on it, I'd want to know if they changed or added fluid, what kind they used. If it was anything except Chrysler ATF+4, that can cause serious problems.

  • The fluid was changed about 4 months ago by a non-dealer (not sure of the kind of fluid) and changed again about a month ago by the dodge dealer. Surely they would use the Chrysler ATF+4. I will do some checking into that. As far as computer problems, do you recommend any particular shop that can check this out?

    Find a Dodge dealer that does notable Ram business. They'll need to run checks on the various sensors that operate the trans.
