Dude...... It's crazy how something so simple as that can cause so much issues. This hack literally was the solution to all my problems. It's a completely different truck now. As if it was shifting through gears like a new truck. And my truck has 313,000 miles. Thank you so much. I'm in love again with my truck.👌
I’ve run a fass 150 for as long as I’ve owned the truck, and the pump which is on it has 330k miles on it. As long as you keep up with filter changes and run a Fass, your VP will last a long time.
Man this video seriously made my life soooo much better......I’ve been fighting this issue for months and was about to just give up. Amazing how easy it is once someone else diagnoses it for you. THANKYOU
uzi4you2say I think I am having this same problem the only thing is that I have a 2005 dodge 2500 hemi. Is it possible to be the t/c lock issue even though it’s not a diesel truck?? Please help!!!
I just ran a new ground from passenger battery to the ECM ground strap location and completely cleared up the RPM jumping around. I will also get FARADY tape and rerun the ECM wire hes showing. My truck is a 1999 Dodge Ram 2500 5.9 Cummins 24V.
I too have been fighting this shit. 418k miles and it always returns every year about the same time. all the gadget upgrades then reassign ground wire. Outstanding
AC Noise from the alt does NOT just affect the transmission. Having a manual transmission does NOT mean you do not need to worry about AC noise. AC noise will kill the VP44, ECM, PCM, dash cluster and more. Basically every electrical comment is at risk. These Cummins trucks (specifically the two computers) are particularly sensitive to AC noise and very expensive to fix. Moving the ground wire or adding noise filters is a bandaid that make the issue. If its measuring over .05v you need to replace that alternator and test again. If your using cheap parts store alternators, be prepared to swap them 2-3 times before you find one that has good AC noise. Always Buy, install and then test in your truck. Don't trust the "bench test". Test it with the truck running, additional accessories (lights and what not) Off and at the Alternator, not the batteries.
You can also tin foil, electrical tape the ground wire then reroute that's what I did along with better alternator and apps noise isolater to new ground.
KeTO BeasT84 yeah it works until the problem returns when your alternator is still functioning, but not optimally. Removing the capability for induction of current into the system makes the whole system more robust.
@@uzifouryoutwosay it tries to lockup then jumps out then when i get up in speed and it finally locks. If im more aggressive with acceleration it doesnt do it.
That sounds like your OD/Lockup solenoids (specifically lockup) are faulty.They’re located on the valve body, inside the trans, but can be replaced by dropping the pan and valve body.
@@Themarketplacebandit I would check to see the routing of your ground wire. The 48RE is a very similar transmission and in an 03 the topography of the engine management system is more like what you would see in an older truck
Instead of rinning the ground clear to the battery on the pass side could a person shorten the ground an route it to the ground to the battery on the drivers side???????
I would think so, but have fun with going through all that wiring mess. It was hassle enough to cut to back right passed the 3 way connection other side of Alternator cover, but that's where I took it back to and tin foiled, electrical taped then rerouted away from Alternator. Be aware the batteries serve different functions, the passenger is charged by alt and the driver side main powers starter etc.
@@ketobeast8489 old comment, but dual battery setups like on diesel trucks, create one large battery. There is no....driver side battery, pass side battery...... There is only two halves of one large battery, as theh are fully connected to each other.
Shit, I’ve tried this, changed transducer, pressure solenoid, adjusted bands, cleaned battery terminals and clamps, added a noise isolator to the C1 connector on the PCM and nothing. Hit a massive pothole and it came back hunting for gears harder than before instantly after hitting that hole. Kinda leads me to believe there’s a loose connection. Trucks hunts for gears, in and out of lockup, takes off in 2nd at times. I’m at the end of my fuckin rope here. Trans is built and is fine with fresh fluid also. Does anyone have any other ideas that would be a possible fix? Could the shifter on the steering column be out of wack? I’ve noticed if I end up adjusting the shifter on the column as in getting into into D better it tends to act “more so normal”
It’s probably an issue with your shifter or your valve body. 2nd is controlled hydraulically, only overdrive and lockup are controlled electrically. So, you should look at the shifter lever as it comes out of the bulkhead and all the joints on it, as well as the actual selector on the trans. There’s a lever that attaches to the shaft that’s your shift lever, make sure everything is solid there, and from there I would look at valve body stuff. Literally nothing electrical has to do with starting in second or weird shock associated hunting issues.
I have a 97 12v auto, when I apply generous amounts of throttle (usually while going up a grade) the transmission will quickly lock and unlock, feels like a jolt. Also every once in awhile it will completely disengage and my RPM’s skyrocket. If I let my foot off the throttle it will reingage . Does this sound like a similar problem to what you were having? It only happens above 45-50.
rogerthenegotiator69 that sounds like you either need to replace you APPS or calibrate it. Either way you will need a voltmeter to test that it’s within range. It’s nothing too scary though
rogerthenegotiator69 no worries man. Also, relocating your ground wire for your alternator and wrapping it in tin foil will help attenuate any electrical noise induction that may be interfering with your system as well.
nerdanderthal IDontLikeGooglePlus It's very straight forward if you have the right parts. My truck still has the stock ECM and PCM. You will need to jump your neutral safety switch and install the clutch start beneath the pedal. Your cruise control will not work until you can find an ECM out of a manual truck, but otherwise it's as simple as cutting a hole in the floor and doing a tranny swap. I have a video on my channel of my truck with the swapped parts in place here th-cam.com/video/pS2BDJIeaT4/w-d-xo.html Don't listen to the mall ninjas on youtube and forums trying to make it out to be rocket surgery. Unfortunately, it's just not that complex.
1. My transmission has more than a few miles on it and was never maintained by the previous owner. 2. A good rebuild for my auto is almost as much as a five speed. 3. My transmission needs a rebuild 4. Towing capacity will go up with a manual and several points of failure will be eliminated with a swap. 5. Gas milage goes up with a manual. 6. A long time ago my dad told me that automatic transmissions in a truck is un-American. If I were driving in stop and go traffic all day or had a disability an auto would be the way to go. Seems like automatics became more and more popular and can be found jeeps and corvettes now. Seems like their popularity coincides with cell phones - folks need a free hand.
nerdanderthal IDontLikeGooglePlus Well and nowadays, automatic transmissions are far more stout than they were in the past. You make solid points, and my old man would say the same thing. I ask because a lot of guys think that by doing a manual swap, they're magically gonna be able to put 800 horse to the ground and run 11's on the drag strip. Though it can be done, I tend to argue that if speed and power are what you're looking for, you need to be a big kid and build your auto. However, for simplicity, and the opportunity to stir your own transmission, manuals are nice. I think that true reliability is subjective, based on your operating conditions and expectations; so it's hard for me to succinctly say one is more reliable than the other. As well, I've only got 60k miles on my manual, and I put roughly 140k on my auto so we'll see.
would this effect lack of throttle I did a 01 24v swap in my 77 Ford ran all my wiring now the throttle feels like it governs out at low rpms won't let me go over 45mph
+Deer Park I would look at your APPS and make sure it's calibrated (more or less your throttle position sensor). Also, did you pull the motor from a running/driving truck?
I’d have to see the routing of the ground wire on a gas pickup, but yes the alternator could generate noise and cause this same issue in a gas pickup, for sure.
@@uzifouryoutwosay thanks man I'll give it a try I know I also have some bad vavle seals don't think that's the problem with the torque converter. I wished they put the 727 in these. I know 3gears aren't great . But the 727 is a really good trans
From what I understand; these torque converter locking and unlocking issues are caused by excessive AC noise coming from the alternator. This is because the diodes are toast. If this isn't fixed, it will eventually fry your APPS, PCM and the PSG on the injection pump. mopar1973man.com/cummins/articles.html/24-valve-2nd-generation/52_transmission-transfer-case/torque-converter-issues-and-alternator-noise-testing-r388/
Pete Morris, I've not heard the frying of the pcm issue, due to inducted voltages, however I have experimented with new and old alternators and found that the only proper fix was re-routing/shielding of ground wires. The other option too is a noise filter which does effectively the same thing. That being said, I've owned 3 isb powered 99-2001 dodge pickups and logged somewhere around 250,000 miles on those trucks, with mileages varying from 190-400k miles, and I've never experienced frying of ecm/pcm/vp44. Not saying it can't happen, just never experienced it myself.
I'm glad to hear that you haven't experienced any problems with the other electronics on your vehicles. I hope I didn't come off sounding like an "alarmist" or some sort of smart aleck, If I did, I apologize : - ) As a owner of an 01 47re 2nd gen, I myself haven't experienced any lock up issues or any other electrical issues for that matter. With 126,000 on the odo and with the original ALT still on it. I plan on checking it for excess a/c noise, if it's out of spec, I will probably just replace the whole unit with one from Nations. they're a little spendy but well worth it from what I understand. GOOD LUCK!
The ONLY proper fix is an alternator that not putting out the noise int he first place... its take multiples some times to find one. China stuff is junk. You can heck out Nations Alternators, there pricy but good made in USA quality and should all have good noise out the door. Or look at a 6 phase alternator, but thats gonna be like $500+
Is this why when my truck gets up to temp it kicks it out of 4th overdrive, my problem is when I leave it sitting it will shift but when it warms up or like literally 5 minutes of driving it kicks it out of 4th and I drive in 3rd at all times
Mopamans fix is more in depth, but this is an easier/quicker fix depending on the state of your alternator and how much noise it’s generating (mr myagi voice) “samea same, onery different”
Michael Moore I believe you in your specific situation. But it’s essentially the same idea. Minimize the capacity of inducing a current into your ground, thus throwing off your PCM. I’ve personally used this method, and over the last three years of it being on youtube, I’ve had a lot of people tell me that it’s worked very well for them. Like I said, it’s not as in depth as what moparman does, but for a lot of people, this has been sufficient.

I run new grounds to the pcm to fix it. Anything else just stops it for a wile. Had the truck 15 years. This final completely fixed it five years ago.
bigblockcutlass123 mine is having the same problem but is also cutting power every now and then. Would this cause that as well?
Cool... is there a way you can make a video on how you ran grounds to pcm???
You can also tin foil, electrical tape the ground wire then reroute that's what I did along with better alternator and apps noise isolater to new ground.
KeTO BeasT84 so tin foil and ground chasing in both instances didn’t fix the issue. Re-routing and noise isolation are going to be your best bet.
@@uzifouryoutwosay New alternator diodes or new alt. Tested with less ac noise is real fix.

You need to check your alternator diodes for AC current
