2nd Generation Dodge 24 Valve Powertrain

I bought a 2002 cummins recently. There is a wiring harness that runs under the fan shroud. The fan shroud is broken and the wiring harness got cut in half by the fan. I am trying to splice the wires back together but there are about 5 wires that have an exact duplicate color so I am not sure how to differentiate them to get them spliced correctly. Can anyone help me with any info on splicing them back together?

Friday I serviced the transmission, including taking out the valve body to replace plastic accumulator piston with metal one, (manual valve?) to allow flow to torque converter while in Park. I have noticed the last couple of days that the truck - even when warm after 30 mile drive - idles higher than normal, around 1250 versus 800ish RPM. This is in park or neutral. The tach isn't wonky, I only looked at the tach because it sounded fast. Idle while in drive seems normal. I have checked the transmission fluid after 30 mile drive home on interstate, truck in neutral on level ground and it's in the middle of the hatch mark, same as the last 30k miles. Fluid is not "foa…

Hey there I just hooked up an OBDLink to my 24v and noticed some strange boost readings. At idle I’m getting 12.4 and at full throttle about 22.4. Is this the app not reading boost correctly or should I be checking my map and wastegate? It’s an 01 HO

I was talking to moparman1973, I’m having an issue with uploading tunes onto my quadzilla v2 on a 99 vp44 truck, it keeps saying the tunes are failing when I try to do an upload, he told me there having problems with the iquad like mine and something about @Me78569 having instructions on how to fix this problem, any info or link to those instructions? @Me78569

I have a leak at my radiator drain. Want to replace the o ring on the drain plug. Anybody happen to know the size of the o ring ? Thanks in advance !!! John

I'll try to make a long story short. I had the clutch changed a few weeks ago. Because of where I mounted the high idle switch down by the gear shifter I removed it. It's one of the first I switches I got it from DAP. I previously already changed the open wire in the harness because it started having problems. So back to this problem, I put the switch back in and the other day the IAT temps seemed weird on my scan guage 2 so I removed the switch to check it all out and make sure all connections were good. While doing this the power wire going to the switch for the indicator light came off. Me being the idiot I aim, I solder it back to the wires coming from the resistors. …

Hey there so I’m a noob to this forum but not the cummins scene. I have utilized this forum for tons of info in the past with great success... until now I’ve never not found the answer. Long story short I installed a quadzilla adrenaline in my 02 2500. 10 seconds after starting the truck started smoking(so bad the fire dept was called by 3 neighbors) and developed an intense fuel knock. Contacted quadzilla and sent the module in, they confirmed it was a dud and replaced it. The iquad was claiming with the truck off that it made 42psi of boost off the map sensor(replaced the map with a cummins sensor as per Marco at quadzilla recommendation when the original sensor was fin…

Hey, dont mean to start a new topic, but I have a question in regards to how much oil is in my 6 speed currently without draining it all. Like how much oil can you put in from the fill hole on level ground? What about bolt at top of the pto? Only asking because I had a shop( which does good work usually) drain and fill it. I would've done it myself but time is something I dont have a lot of. I bought the oil, 6 quarts redline, and when I got truck back, I had 2 quarts of oil still left. Was told it may have had left over oil still in? Sounded odd, but they said they would check it. Brought It back, and a mechanic i havent met there came in and got …

So I have had the first major problem with my 02 2500. Got the truck out Saturday afternoon to go to a church dinner. Get ready to leave the dinner and my truck won't start. When I key-on the ignition I don't hear the FASS kick on, then I notice the wait to start is flashing. So obviously I am assuming the worst, a dead ECM. The truck would just crank and crank and crank. Call for tow and of course it will be awhile, so I leave the truck and wait at home. (A side note, before I left the house that day when I first got in the truck and turned the key on, the FASS was delayed in kicking on. Thought it was weird, so I turned the key off and back on again and everything …

I was just getting on the highway working my way through gears and I got to shift to fifth and it won’t shift out of fourth but clutch still disengages drive. Help

I thought that I would post a thread just in case anyone ran into the same thing I did. Last week my wife drove my truck to an appointment while I was away on a business trip. She called and said that the truck was stuck in 4th gear and she couldn't get it out. Since I was 4 hours out there was not much I could do. Luckily she kept her cool and got it off of the interstate and into a hotel parking lot. When I got there, I just assumed that it was jammed somehow. No manner of pulling or pushing would free it up. I drove it home in 4th by shifting from 4L to 4H on the transfer case. Pulled the shift tower off to take a look. Apparently the shift tower had worn to the point…

OK guys looking to what you guys have for throttle position percentage reading at 70 MPH cruise with 3:55 gears and 47RE trans thinking mine is a little high from what I can remember but I could be wrong mine is at like 24-25% at 70MPH cruise I thought was usually around 17% before just can not remember??? Thanks in advance reading from quadzilla adrenaline

Today in my work load was my shop owner asking me to replace his water pump. Pretty straight forward. Got to the part of refilling the coolant in the system. I did like I normally do is remove the thermostat and fill when I popped thermostat out and the bypass flap is missing. Now this is the second Cummins thermostat seen fail.

01 Cummins won’t shut off....replaced ignition and still won’t shut off...any ideas?

A couple of weeks ago i did @IBMobile grid heater bypass. Everything worked great with no issues. This morning when i went to leave for work i turned on the grids. Fired up the truck, everything normal. Turned off the toggle switch for the grid heaters while the grids were powered up. Started driving and noticed my digital volt gauge was dark. Didn't think too much of it. It was cheap and figured it just died. Shut the truck down at work and realized my turbo timer was also not working. Checked everything and both volt gauge and turbo timer are fried. Took a little to put it together but i believe a current spike from the SS-581 solenoid destroyed them. I did some researc…

hey guys bit of a long story here but I need some help. my truck started to run a bit rough and losing a bit of power so I checked the lift pump pressure it was at 4 and zero at wot. so I changed it out new pump pressure 17psi, then it started to start hard in the morning and showing a 1693 code. Eventually it died on my way to work and wouldn't start so I changed the injector pump and before I even tried to start it threw a 1689 and a 1693. I got the truck running no problem cleared the codes and took it for a drive and it had low power and died 3 miles down the road and the codes were back. towed it home bleed the injectors and it started again runs and idl…

Wont shift to 3rd or od

Got the high idle switch installed and was wondering about using it in MPG mode with the XZT. I read that in MPG mode the high idle switch alters timing. So does the XZT when its in the 65 hp setting. Any problems using the 2 together?

Previously I discussed ongoing issues with my 47re, including no communication, no overdrive, no tcc lockup... I had already condemned the pcm and bought a junkyard pcm to replace it with. It has the same issues, could I have a bad pcm from the junkyard or is it more likely i have a wiring problem that either stopping communication or frying the pcm? What wires should i check before sending my pcm to be rebuilt?

I’ve checked every fuse known to man....have everything but running lights, anyone have any ideas on what I can do next?...01 Cummins
