That’s super interesting. Thats for sharing. I’ve been running a South Bend 3250 since 2008 in my 01 Cummins 6 speed. And it’s always had problems going in to first and reverse. Maybe it’s time to try something new.
I am very impressed with your workmanship and experience in these. If I ever need my 6 speed rebuilt I will have to ship mine your way. Excellent video to see.
The nv5600 is an excellent trans. If you know how to work on it. I get overly picky on mine and always ask trans guy on how many they have worked on prior to me doing a standard service.
Wondering if you would have a solution to my problem (and if its the clutch then ill be buying valair which i likely will already because my south bend shifts like garbage). I have a 12v cummins with a nv4500 i rebuilt with all high quality parts, with the south bend organic/ceramic dual disk and upgraded input. I have a np241dhd and dana 80 disc rear end that was recently rebuilt. Last year i got a 5" aluminum driveshaft made because my slip joint failed on my stock steel shaft. The aluminum shaft amplifies a god awful rattling sound that i compare to a concrete saw. Its significantly louder than my exhaust under load, especially in 4th. Would swapping to a valair eliminate this sound? Its unbelievably frustrating to spend $3k (canadian) on a clutch and $1500 for a drive shaft for it to make my truck sound broken all the time. Yes, we get absolutely screwed on cost, its Canada.
I have done a lot of work "especially engine" on my 05 dually. Have a 5th wheel and travel the western mts. This has been in my plans lately But so far have just triple wrapped exh. from engine past the trans. Good maintenance and quality lube is important but heavy loads long hills and high temps are reason for added insurance.
I had my 5600 rebuilt a couple years ago and every since it’s been rebuilt my shifter seems to float across the rack and you cannot feel the “detents” of the gear making it very difficult to find each gear. For example my shifter goes to the left past 1st and 2nd I have to come back to the right a bit to find the gears. Same goes for reverse. Any suggestions? I had the trans back at a different shop for an input shaft and they didn’t have an answer for me. Thank you !
I have a NV5600 on my 2005 Dodge Ram 2500 4x4 5.9 diesel . It has a South bend Duel Friction and the throw-out bearings makes a dry grinding sound . This is my second Throw-out and from the start the second one makes the same dry grinding sound. The mechanic said he thinks it is . So now after seeing this video maybe its time for a change . I load a 3,500 lb camper and pull a trailer that when loaded is about 3500 lb . Which Valair would you recommend for me application ? So tired of the grinding sound every time i put the clutch in . People look at me and its embarrassing What would the price be for the Valair ? Thanks
So have you actually seen a cracked or damaged aluminum rear tail housing from use? Id take aviation form a gasket with a paper gasket or type 2 form a gasket any day over RYV.
Yes I have, there’s several transmissions that have come in the shop ran low on oil from cracked housings. We only build them with cast iron housings. For sealant, Permatex MaxFlex is our choice for nv4500s and it works great.
@@GregariousAntithesisI bought a super cheap one it was $100 dollars honestly the casting seems pretty nice and the sealing surfaces and machining all seems to be pretty nice It seems just as high quality as the original just heavier duty. I haven't noticed any leaking after my rebuild or anything.
Awesome! I'm in the process of "refreshing and upgrading" my 12v 2nd gen. Mine is a 2wd nv4500 truck and i bought a matching 4x4 donor. Already have the donor truck stripped to bare frame. Cleaned, sanded and painted. Parts collecting for the summer (Hurricanes and humidity stopping progress lol) then rebuild onto the 4x4 next winter. Looking forward to any cummins related content.
Nice 2nd gen! Can't wait to see what you do with it.I have the freedom offroad control arms and trac bar for the last 100,000 miles and love them. Quality parts for a great price.
This is my truck, Andrew got me all fixed up and back on the road. The man knows his stuff and treats the customer right. Hopefully this will be educational for others; replace the retainer when you do a clutch replacement on a G56!
I have a 03 dodge 2500 5.9 with a nv5600 6 speed the truck has 230k miles on it im the second owner, anytime the clutch is engaged even in nuetral i get a really loud like gear clashing noise its not noticeable when im driving or sitting in a parking lot but if you get out and stand next to it you can hear it and also when im in a drive threw its really loud with a wall being up close for the sound to bounce off of. Would you have any idea what would be causing this noise? Ive seen around on the internet from trying to diagnose it myself that it is very common to have a bit of a rattle in ur transmission but id like to make sure.
Yes, that’s why we highlighted it. The plastic retainers are supposed to break on first depression of the pedal- the throwout was stopping the movement of the clutch fork entirely.
Great video, i swapped my 98 12v from a 47re to nv4500 and it has 400k miles on it and hasnt given me any issue at 450hp. This winter i plan on common rail swapping my truck is there any upgrayou can recommend specifically to handle the power of the common rail engines when i start turning it up
Unfortunately, I can almost guarantee you start having issues if start modifying your common rail in front of an NV4500. These transmissions were never designed for the power that is now commonplace in the later 5.9’s. The factory torque rating is 460 ft-lbs… You can either be very careful with it (but what fun is that?!?) or start budgeting for an NV5600/G56/ZF6 swap.
@@longrangegear I see, i planned on tuning it and running a factory 6.7 turbo with a controller for the vgt/exhaust brake. I may definitely need to look at the 5600
Have you ever paired an NV4500 with a NP205 that have different input and output splines resulting in the use of a coupler which is said to interfere with the output seal on the trans? If so I'd love to know as I am in the process of swapping a 2wd NV4500 to 4wd and mating it with an NP205. Also, what is your opinion on MT90 apposed to MT85? I am told the viscosity is the only difference. Amazing video series on this by the way, seen many and this one is by far the most cut and dry and to the point!!!
Usually when pairing with a 6 bolt NP205 you’ll use a coupler and omit the rear transmission seal, and instead use a GM style gasket or RTV between the transmission and Tcase.
@@longrangegear Could leaving the seal uninstalled cause the trans and t-case to swap fluids?? If so I'm curious if the trans and t-case can run the same fluid. In this application gears are gears, the fluid is only particular to the carbon fiber synchro's in the trans?
@@robroy5729 they would only begin to mix fluid if your tcase input seal failed. Your tcase requires a heavy gear oil, the trans requires a very light synchromesh-type oil. They should not be interchanged.
Can't wait to start the rebuild and conversion from 2wd to 4x4 on my NV4500. Thanks for all the informative videos. Ill be re-watching them in the garage during every step. You aren't kidding about the green sleeve compound. That stuff is incredible. Used it on my 12v suburban swap for the hydro brakes to hold the gear on the power steering pump. Waited a tad to long to get it pressed fully on and man was it a bear to do afterwards.
Ok dammit…… A month ago when I got my 12 valve I was afraid of this little project but after watching you guys multiple times I amd confident enough to do it myself.
Thank you for the help, my input shaft just sheared of on mine and in the middle of tearing into it had some prices fall out, being the synchro hub springs and pieces.
Would you convert a 12 valve to a propane burner. 10.5 comp. Ford six HIE. Imco 200 carb. Volkswagen distributor gear off of acc drive. To get the timing right. ???? Now It WOULD WORK. 😊
At 1:03 you said the slider only goes on one way and that you had a video on how to assemble. do you mean there is only one orientation (taper up or down) Or only one rotational position?
