2nd Generation Dodge 24 Valve Powertrain

So how much are good used ones going for? I have chance to buy one for $1200. Don't really need it but I hear they are getting harder to get, thought as long as I have my truck it may be a good idea to have a spare until I get rid of it someday, then I can always sell it . Says it has a 1 3/8 10 spline input shaft, not really sure though if that's the same as the one in my truck...anyway of telling short of tearing it apart?

i came a cross an old thread on CF discussing pros and cons of the nv5600. the only thing unusual in it was a single post by someone stating you should only use an exhaust brake in 5th gear. no mention as to why or any responses to the post. i am just wondering if any of you have ever heard of any reason not to use an ebrake on a nv5600.

Im new to the nv5600 so I been digging up info on how many qts should over fill. I read everything from 4.5 to 7qt. Im running 6 in it now but if any of you are running 7 Id like to hear from you. Thanks

Ok, so I feel like I got burned by a cheap made in tiwan SKF output seal. Synopsis of my issue: 02 4x2 quad cab nv 5600 217,000k Tranny output seal started leaking and I had one bad u joint. All original equipment so I guess it's no surprise. So I figured I'll just do everything, new output shaft seal, all new u-joints and center bearing, change the trans lube & install trans Quad 4x4 filter kit as well as a 1/8" weld bung on the drivers side pto cover for a temp probe. Did all of the above, took for a 3 mile test drive & the output seal failed - popped out. Luckily didn't drive to far so I didn't lose all of the …

As the title reads, yes my 5 speed NV4500 ate itself at 184k. Some quick background, I bought the truck used with 138k on the clock. Now after some conversations with @Mopar1973Man I should have dumped the oil in everything on truck right away after purchase and replaced with new but i did not (now regretting it). I dont believe the fluid was ever changed. Now, I have been searching for a rebuilder near me to get this done. I was thinking of doing it myself but decided it may be best to leave it to someone that knows these things better thatn i do. Ive never rebuilt one before. Problem is, i cant find anyone around me that does it anymore. So no…

I have aluminum flakes in my NV4500 oil looks like metallic paint What can be wrong? What is aluminum in the transmission?

Hello everyone I am debating if I should junk my nv6500 and get a 5 speed nv4500HD. Can this be done on a 99 2500 4x4? Has anyone done or heard of this being done?

I have a nv4500 that is making a noise in 4th gear when slowing down between 1000-1300 rpms it was rebuilt 2k miles ago it has a southbend clutch its not a grinding or clunk sound more like a bearing ? Could it also be the harmonics in that gear when slowing down ? My damper wobbles a little need help !!!

About a year ago I had the clutch replaced, went with a South Bend DD, I pull a 14k 5er, so this is the clutch I was advised to get. In retrospect, not sure I'd ever get another south bend, clutch is so dam temperamental, and seems to really suck when the humidity is high, lots chattering. This leads me to the main question, since this clutch was installed shifting gears when moving there is noticeable "resistance", it's worst trying to get into 3rd gear, if one pushes on the stick to hard it will grind bad (did not have this problem with stock clutch, but I did notice with stock clutch, that 3rd gear would grind once in a blue moon, I just figured I had screwed up th…

Like the title says, my transmission is hard to shift. Real notchy, and sometimes a bastard to put into gear or reverse. It's rebuilt, and has maybe 400 miles on it. Running Lucas 50wt oil as recommended. But it just doesn't feel right. In another post I stated I had the clutch pedal adjusted way our to get rid of the slop of no bushing. The clutch seems to release ok, it doesn't crawl when in gear. But I worry it's something else. I will say when I put the transmission back in I fought to put it in the last tiny bit in the pilot bearing. Had to torque it down, but I did it as slowly and gently as I could,and the gap was less than half an inch when I started. Not sure if …

First off let me say... I've followed some of the advise here and double checked a bunch of stuff. The transmission is over filled enough that the sensor is submerged in fluid constantly even in 5th gear and transfer case in neutral. As for the shift quality after nearly 1,000 miles already is still really tight feeling and not sloppy. As for transmission fluid temps empty running I see no more that 130*F tops at 68 MPH after 40 miles of driving even climbing grades. If the morning temperatures are down around 45*F it takes nearly a full 20 miles to rise off of the 100*F mark of the gauge. At midday with 75-80*F temps outside its barely reaching 130*F with flat travel mig…

Hey guys, Late last year I noticed my front passenger side axle seal was leaking, so I had a local place replace it. Well just the other week, approximately 7 months after the replacement, I noticed it was leaking again. I took it back to the shop and the replaced it again and told me to keep an eye on it and let them know if it started up again. Well here we are a week later and its leaking again. What can the issue be??? All I can think of is that they are screwing it up, or the vent tube is blocked maybe. Any ideas? Second question. Last few days it seemed like my trans is shifting a little different. Not totally sure, just kinda seems it. Anywa…

With a heavy heart, something broke in the transmission running along at 80 MPH. 5th gear failed with a horrid grinding sound. 1st to 4th still works find but there is a loose object for sure like a 5th gear nut. But you can't put it 5th it grinds bad.

So I've been hearing some chatter while coasting on the highway, i initially thought I was just in need of a valve adjustment because it sounds so similar to chattery valves I've heard on other engines. Did a valve adjustment and the noise is still present. After some long drives on the highway I realized if I'm coasting and put the slightest bit of pressure on the clutch the noise goes away. And when I say slight I mean slight, you could lean and empty sneaker or work boot on the pedal and the noise dissapears. I also noticed if I'm coasting and press the clutch pedal in and let it out the noise is gone for 5 seconds or so then returns. There's no noise if I coast for a …

So about this time last year I installed a Valair 13" Upgrade clutch supposed to be rate at 400HP and 900fts torque ( I dont think I'm there but I could be wrong ) and I had zero problems but maybe 2 months ago I went to pass a line of vehicles and bumped up the Quadzilla up romped on it and slip went the clutch. Now it will slip on any setting except stock when I get on it and progressively has gotten worse. So now I'm looking at going to a dual South Bend but before I drop a grand 1) Anyone know of anything I should try to get the current clutch to heal itself or so to speak cause I dont!? 2) I am thinking about doing the 1.375 input shaft upgrade, is it nece…

Hey guys,Well yesterday my NV4500 decided to lose 3rd/4th gear. Now I'm trying to decide on what to do.... I've seen that ATS and Haisley Machine both sell a NV4500 and I know I can buy the parts to fix mine. But my problem is I'm trying to decide what the best bang for the buck would be.... Would I be better off with a NV5600 or stick with the NV4500? The FSO-6404a swap is pretty cool but I'm not sure about trying to source all the parts right now. Any opinions on the ATS or Haisley trans or any other places and parts outlets?:shrug:I know I make well over what the NV4500 is rated for and I'd like not to have breakage down the road even though I don't generally drive tha…

Hello from Germany.... I just installed a Valair single organic disc in my truck. The previous clutch went bad due to the input shaft seal leaking, y’all know the rest. I did replace the seal. I got the whole clutch kit from Valair, 13“ flywheel, pilot, throwout, etc. Even went the extra mile and got the ARP flywheel bolts. The trans used to rake a little on the 2-3 shift if I was beating on it. Gotta show those pesky German VW drivers what the ‘ole dually can do from time to time. After the clutch install, I can’t do a 4-3 downshift, at least like I used to. If I slow down to where I normally would shift to second, it will go into third. I never had any do…

Anyone happen to know what size plug and thread the fill plug on the NV4500 is?

So I bought the filter kit for the fast coolers buddy has the other style of filter the yarn filter. Is there any problems with running two filters or is that wrong.

261k miles and my NV4500 finally died. Not the 5th gear nut. I lost both 3rd and 4th gear. I was just leaving my place pulling the trailer back to New Meadows, ID with the a truck on the deck. Got into 3rd and the stick was rattling oddly. Poured the fuel to her to get rolling and it popped out of gear. Difficult to get into 4th. I knew the transmission had lost a bearing or something. Got up to New Meadows flats and check everything over no leaks. 1st gear works fine, 2nd gear works fine, 3rd pushing against you and BANG! Then tried 4th its missing. Rowed to 5th and barely had enough power to get the truck going. I had another 5-6 miles to go before cell service. I got a…
