2nd Generation Dodge 24 Valve Powertrain

anyone having good luck from a parts store water pump? I am going through 1 a year and I am kinda sick of dumping coolant in the street.

I have a fairly good idea of how the lockup switch works. I am curious though, if you install a switch but don't have the switch on, will the converter lock/unlock like normal? Do you have to control it 100% of the time if you install the switch? I'm not really sure I need or want to do it, these are just questions I keep asking myself every time I see a post related to it.

Today making a drive to drop off some deer meat to be packaged, my trucks alternator voltage jumped to 18v for a couple of minutes, then went back to normal. First thing I am going to check is my grounds. If they check out to be clean and good should I put in a external voltage regulator like on the 12 valves?

Ok gang... I'm going to share a few tidbit of information for advance OBDII tinkering. If you happen to have a OBDLink or ELM327 tool you should be able to tag along here. I will have to give a bit of thanks to @Me78569 for getting me started with the Bluetooth terminal on Android. Once I had that I could directly communicate with the OBDLink and pass commands to it. So starting out I passed the command... ATSP0 This basically tells the tool to communication with the detected protocol of the vehicle ours happens to be ISO 9141-2 protocol. After that I passed the command... 0100 Which happens to be PID Mode 01 with the PID 00 which tells th…

Next weekend when I drop the trans to install a new southbend I'm installing fast coolers and a trans temp gauge also. What should be considered hot for these trans? I'm running royal purple syncromax if that makes any difference.

Ok I love the sound of my truck, it’s straight piped to a large tip and has an open air box with great turbo sound. But I have to say it, it’s too loud. So simple question, can I make it quieter without sacrificing flow? Looking maybe at muffler or dual mufflers or maybe some sort of attenuator. I daily drive and use this for normal stuff like going through a drive through or stopping to talk for a second with friends or other parents at my kids school. But I also use it like a work truck, towing and hauling campers, equipment, firewood, etc. Can anyone help with this dilemma?

Too good to be true, the truck was running good, not overheating. Last night, I saw a puddle, maybe an oil leak. I checked and after running, it is leaking a mixture of oil and antifreeze by the front case, above the oil pan. It's lost a quart, it runs fine, but the killer dowel pin is a possibility. 2001 shouldn't have a killer dowel pin? Has anyone heard of this, and is the likely source the water pump? The engine runs, so the engine seems okay. Thoughts? And thanks for the help.

Converted 2001 diesel to 5 speed no cruise cut black with white tracer The check engine light with code P1899 " P/N stuck in park or gear" then the truck would govern to 1700 RPM until code is cleared Help

Hey guys, This is my first post over here. Id like to thank Mopar1973Man for having this forum and for all the information he contributes. The trouble code walkthoughs are an amazing resource. I am trying to resolve P1689 and P0215 DTCs. Truck: 01 QCLB CTD Auto 4wd. Pertinent upgrades: FASS system 95gph, smartry and original quadzilla adrenaline. There are lots of other upgrades, but none that should relate to my question. Backround: Truck was sitting for the better part of two years. When I stopped driving it, it was running well. When I came back to start it again, I had a no crank issue that ended up being a bad ignition switch.…

fluid leaking between tcase and trans . have change seal 3 times ,cleaned surfaces, replaced with double lipped seal, still leaks yes I checked tcase seal not leaking from there. had trans rebuild after 220000 miles never leaked before rebuild. any Ideas to fix it besides sealing flanges where they mateup ?

I contacted Cummins to see about a replacement ECM. They have them for $2700. The 3946242RX part number also goes by ENCORE CM551A. But then I also see a 3942860RX (CM550) that also claims to work with a VP44 for $1500. And also a 3944124RX for $1300. But these other two, I have no compatibility info on. I love how the overnight shipping for a 5 lb. part is $250.

Hello Everyone, Well over Memorial Day Weekend the 47re began its slide to the point of no return on my way back from my camping trip. I knew this day would come when I purchased the truck (mechanical items don't last forever) so its no real surprise (still feels like this though ). Taking that into consideration, I have always planned to convert my rig over to manual as I am a 3 peddle guy. I am not concerned with the $$ (sort of) but am really concerned about doing it right with a solid end product. I decided on the nv4500, so I will be needing help from all of you 5 speed owners (or past 5 spds). The goal of this thread is to seek knowledg…

I've done the P1689 troubleshooting steps. I made it to the end of step #8. According to the steps, that means my ECM is bad. In keeping with the idea that "it's probably not the ECM," I've been trying to double-check the communication between the ECM and the VP44. I tried to put an oscilloscope on the VP44 today, to see if I could see the data. If I see the ECM's data, then it's the VP44 computer, not the ECM. I saw something that looked like PCM data, but I couldn't figure out how to set a stable trigger on it. I put channel #1 on the black & white wires (Pins 1 & 2), and put channel #2 on the green wire (Pin 8). Then I tried to tr…

I have read tid bits about putting 2 stroke oil in diesel fuel. What are the benefits? Lubricity? Fuel mpg? How much do you put in a 34 gallon tank? Is there a special type? Thanks!

Hi everyone sorry for the silly question but I have a 2000 Dodge Cummins auto with 250000 miles I just bought put a exhaust and intake in it . It ran perfect installed a Fass system on it 2 days ago while priming after the first bump the pump kicked in and started it’s cycle check engine light came on ! second time it didn’t cycle and wait to start light didn’t come on tryed a few more times and pump wouldent come on waited a while and wait to start came on and pump came on primes it bled it and started right up but I have a p1689 code it starts right up and throttle response is good I haven’t driven it yet but should I clear code and hope for best or is it prob gonna hav…

This weekend I'm pulling out my god forsaken NV4500 and putting in a 5600. I have not for the life of me been able to confirm or deny if I'll also need to swap PCMs. My thinking is no but that answer is pulled completely from my arse. Both trucks and all parts are 2001s. I'm over here with random forum print outs and the full stack of FSMs like a mad man with no answer lol.

I have a 2001 Dodge 3500 and this thing has got a few issues. My lights are flickering at idle and the truck is running rough. Also my gauges the volts and temp gauge will go to zero then come back either by shutting the truck off or just driving it and coming back up mysteriously?? I have done the external voltage regulator swap and it help for a couple days, but then starting acting up. I know its not a ground issue because I have checked and rechecked them. The batteries are brand new as well a the alternator and they were both checked again to be sure. What do you guys think? Maybe the PCM crapping out? The only codes on the truck that I had was PCU 1594/1693 and ECU …

My 2001 Cummins 6 speed cruise control has went erratic . Could someone tell me which it is the ECM for the PCM that controls the cruise control

I ve always told myself if the raptor ever gives up I'm going with a mechanical pump, and so the other day it started giving me fits and loosing pressure, I tried to adjust pressure up but the electric motor just barley running and sound sick so I just gave up on it, and ordered a fuel boss from GDP. My plan is to keep the plumbing as simple as possible, by eliminating a back up electric pump altogether, just dont see a need for it, and if I ever have to prime I will just use the cordless drill method like on filter changes or something. (also going to stick with the factory block mounted fuel filter for heating purpose) So I plan on tapping in on the 1/2" line from …

Hi all... I discovered two cracks in my stock manifold. I have searched here and could not find too much... Can someone recommend a replacement for me? I would like to put something in that I do not have to worry about again and perhaps something with a port already installed for my EGT probe. I do not plan to add any performance upgrades... except maybe 75-90hp injectors down the road when these get tired. Thanks in advance..........
