2nd Generation Dodge 24 Valve Powertrain

Over the last couple of weeks I noticed my TC was acting weird. When its engaged over 45mph and I hit the brakes the TC disengages like its supposed to but then immediately reengages as soon as I let off the brake and its a noticeable reengagement. It has never done that before. It would always stay off unless I got back on the gas pedal. I scanned for codes and it had 2 codes. One for APPS low voltage and one for charging system low. So I bought a new Timbo APPS and installed it today. The TC is still acting the same. I checked the alternator and it is charging normally. I did notice that the AC voltage is up though. When I first did the WT mod the AC noise was…

Does anyone out there know how to troubleshoot the intake air heater?

Just checking out there to see whats the latest on apps sensors. I assume Timbo apps are still the go to? I looked up TPS on Parts Geek and it showed the entire bell crank included for 180 bucks just curious if anyone has tried them.

I finally pulled the trigger. The OEM filter had to go. It's been on there the 3 years or so that I've owned the truck. Filter minder wasn't showing anything but it was filthy anyway. So it was time for a BHAF. I had to replace the air filter anyway so why not upgrade?

I'm asked frequently why I consistently "tinker" with my truck even though it's running good, no maintenance issues to address usually, just want to flip the hood and stare in amazement sometimes. But, this time I spotted something while I was installing a BHAF this morning. The lower exhaust manifold bolt on the rear cylinder was backing out! I grabbed the tools and tightened her up and checked the rest. The upper bolt on the rear cylinder was about half a turn loose as well. All the others were fine. Glad I caught that!

I'm asked frequently why I consistently "tinker" with my truck even though it's running good, no maintenance issues to address usually, just want to flip the hood and stare in amazement sometimes. But, this time I spotted something while I was installing a BHAF this morning. An exhaust manifold bolt was backing out on the bottom rear cylinder. Had I not "tinkered" with the truck this morning I would not have spotted this and possibly lost the bolt all together. I tightened this one down and checked the others. The upper bolt on the same cylinder was about half a turn loose, the rest were good. Glad I caught that!

So I've been getting familiar with it a little, its still greek to me. I havent tapped the vp yet, just trying to see what to monitor. Went to youtube and saw a setting that had 9 different things in a square box with a lot of info on it. Im running an Iphone and maybe its on on it because of that I dont know. But cant seem to there from here. Anyone know what Im trying to explain that can tell me what to do to get it on my phone?

Hey folks, It seems I’ve gotten myself into a situation. About 2 weeks ago my alternator started going out. It would charge fine for a while then drop voltage to 12.3-12.4 and sometimes completely off to around 11v. Monitoring with the gauge on my edge. When charging it would bounce from 13-14v. This started when I was about 300 miles from home. I limped the truck home without replacing it and noticed that on the back of the alternator the clip which secured the plug had broken and would not click and secure. Figured this was my problem and engineered a zip tie fix but didn’t drive the truck again until yesterday. On that drive the truck started giving me the 30 sec…

3500 02 cummins drw hey guys i just took off my drain plug for my rear diff after driving about 3 weeks after changing the oil right after i purchased it, when i took the plug out a bunch of pressure released and went pooof. when i inspected the cap it had a coating of what looked like a gray silicone but it was obviously metal. ive never seen anything like it, no chunks or long bits just what looked like drywall mud. would this be normal? i just got the truck and when i first serviced the rear there was little no no metal. i put75-140 in the rear. i dont know if this would make a difference but i ended up having to repair the front end diff as it was pus…

Hey everyone, new paying member here, having issues with my truck and looking for some guidance. My truck is an 01 24v HO. I have had zero drivability issues since purchasing it about seven years ago until yesterday. Driving down the road as per normal when the engine just suddenly shuts off. I coasted it to the side of the road noticing the check engine light was on so immediatley cycled the key to view codes. I was met with P0230, P1688 and P1689. Luckily I was semi close to my shop so had some good Samaritans help me push it the rest of the way there. The truck is a crank but no fire scenario. I first turned the key on and confirmed the lift pump started and primed. I …

All - planning a VP44 replacement soon and I'm wondering while in the vicinity if I should take care of a few other things. Namely tappet cover gasket, vacuum/steering pump seal, cam sensor. Think this "while i'm there" question has been asked a million times. What say the folks here?

I have a 317k mile truck that only sometimes, runs poorly in the lower gears. 11k miles ago, the original trans gave up the ghost. A friend of mine built a trans with a triple disc Suncoast converter. Immediately the thing drove like crap. Stock truck, no mods, 2400rpm just to 2nd gear and BANG! shifted up into 3rd. And same into od. There's honestly no way to make this long story short. This last Thanksgiving, I spent it under the hood, doing the w-t ground mod and apps reset. So after it was done, I took it for a test run. Upon startup, idiot light indicated batts=no charge. Stopped at the store 2 miles down the road realizing I never set the 150 amp breaker. F…

I need some help. I have no gauges on my dash except for my tack that works. I have put a new transmission wiring repair kit, I have cleaned all the terminals, I have checked all the wires that I can see and I put a new pcm on it. it will crank and drive but i have to start off in first and to get it started going then I can put it in drive and it will shift on its own. Im about ready to drive it off a cliff. (lol) any suggestions will be much appreciated and at this point I'm willing to try anything.

Drove the truck last Tuesday, then proceeded to get awfully sick so truck sat and became a nest. Wanted to move my trailer, no start, and found this. No idea how to take the pins out of the plugs so I can attempt repair. Guess I'll research this over the weekend. Sweatshirt weather today, and Winter begins tonight with sleet and snow, and 4 degrees by Sunday! Late start this year.

Alternator output solid at 14v. ECM voltage output varies, Injector pump voltage varies. Is this normal, if not, what should I do? Thanks in advance, I've ordered the scan tool that was being used so I can check whenever. The problem is I don't know what the typical values should be. Tim

I have just build a 2006 Ford E 350 van with a 24 valve cummins / Allison trans and a 4x4 conversion. I got the engine from an auctioned truck (2001) on the title. Have it running and driving but in limp mode so far. Cam sensor code, After alot of messing around I called cummins and they told me the engine number and ecm p/n are for 1999 but my harness wiring colors tell me it is off the 2001. I have both diagrams printed out and seen the number 9 pin was empty and should be for the cam signal on a 99 so I got a pin from cummins installed it tagged into the grounds and 5 v with a new pig tail and hooked cam and crank up as I think it is meant to be but still throw cam co…

Today I wired in a lockup switch, into an existing switch panel I have that has b+ to the switches. I ran the switches wire to a relay and when I flip the switch it sends positive to the relay. The relay sends ground to the b11 orange/black wire on the white middle connector, problem is it seems when I turn the switch on it unlocks the converter and my speedometer stops working, anyone seen this? Thanks

I rather ask here than pars store or google, what kind of oil does a nv4500 get? and how many quarts ?

Im starting the project today and checking in to see if there is a preference on what gasket maker to go with as Id like to make this a one time deal. Thanks

While my VP is out for repair im resealing left side of block. The old mounting bracket for the stock lift pump is in the way of removing push rod cover and it has a seal back there id like to replace. Am told there is a cap/plug like on old chevy fuel pump where you can cap it off. Not having any luck finding this. Anyone done this and know where I can locate? FOUND IT, LOOK NO FARTHER THAN DAP
