NV3500 Rebuild 

Wow, thanks!

Glad I could help.

Glad to help.

Thanks. They are very similar. There are several that are very close to each other. Here is another version. ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE-kQk21eQoUn4.html

Glad I could help.

little bit trickys right, How do you change the tail shaft bushng?

Bushing driver while it is apart. There is a company that makes several different pullers and installers to fix it in the vehicle. I bought the small one from Snap-On many moons ago, they may still sell them all, 3 different ones if memory serves.

What is the year, make and model?

Yes it should be and yeah trying to hold all that together and drop that housing down at the same time will have you cursing. Sometimes you get luck and it drops right into place. I don't have many tools for standards but can do most. Only ones I can't do are the really large ones, especially the 6 speeds in trucks. Press just is not big enough for them. We do just about any transmission and have had some interesting stuff over the years, too bad I didn't have a camera for some of it. Hope both videos get you what you need. As soon as the parts show up I am doing another TH350 video, as I have moved the camera and it is closer now. Thanks for subscribing and watching.

Thanks, appreciate you watching.

Maybe. If you had the right pullers and could get the race out. You only need to pull the front case off though. You can leave it in the back half.

Glad it helped!

No, you have to take the transmission completely apart.

I would think you could put it in 4th gear and pull the driveshaft and check it there. Could not find any listings on what it should be but I would think it should be like anything else. .005-.012

I know what you are talking about. However, I don't know the name for it. Have looked through all the info I could find and none of it shows it, sorry. When you have the synchro and gear in your hand, you should be able to push the synchro onto the gear while turning it and it should get difficult to impossible to turn. if it doesn't the synchro is wrong or the cone of the gear is worn out. Or in your case since it was replaced, the wrong size.

@@CurmudgeonTransmission Thanks for the reply. After some research i learned that a synchro isnt good just because the teeth arent gone on it like how the gears were haha I'm hoping a fresh synchro will fix 4th gr for the new input shaft. Shaft has play when installed. 1 & 2nd gr seem to have a 2nd ring underneath the synchro rings. Little information is available on part sites - they list them as 3 piece synchros. I bought a some 290-14 synchros for 3rd, 4th and hopefully reverse. I shaved the shift rail a bit and got it to fit into gear better. These transmissions have upgrades with a little machining and tinkering

I had to press it on because it won't slide on.

Yes it should turn, so something is wrong.

Not sure how to take that. At least I made you laugh. Thanks for watching.

@@CurmudgeonTransmission no... Just impressive how you seem to do this from memory, fishing for parts in a box just like a Lego set!

Thanks. Is like putting a puzzle together. I am very good at putting those together.

WIT, Transtar, Links are in the description or the dealer.

Same way you did, visually. The front bearing is a very common failure.

Thanks

Links are in the video descriptions for WIT and Transtar. Either should have it.

You will need a press or bearing pullers to do just about everything.

Thank you.

Thanks, glad it helped. I could not find any info on the magnet, sorry.

Yes, they all face to the front of the transmission. Thanks for watching.

Sounds like a clutch or slave and master problem.

Probably the bearing or the input gear. If it is the bearing you may be able to change it without taking the transmission apart if you have a good enough puller, otherwise you will be cutting it off.

That one is a Muncie 5LM60 ( HM-290 ), looks similar but is different. Standards are a whole different deal than automatics, really can not say till you see all the damage. I am a long ways from there. Visited it once, was really nice. Go here and click on the shop locator tab, they can direct you to someone in your area. www.atra.com/

Thanks. The only thing I can think of is the 3 small caged bearings that go on the mainshaft and countershaft. They go with the taller side facing outwards.

​@Curmudgeon Transmission its strange I did catch that as well there's a groove for counter shaft bearings to sit and turned over the pocket bearing but still binding. My friend recommended I install only main shaft in case and close it spun great. After putting counter and rev idler in rear case I try to close case half together and it binds won't spin without some vice grips on it. And front cover has space in between and won't close either and yes rear bearing in all the way and fastened. Thanks for the help appreciate it

@@Jr-zl1tk Not sure what you have going on there. Something is not all the way down or one of those bearings is longerthan the old ones. I know it sucks but you will need to check every thing you replaced with the old parts.

The input bearing is pressed from the outside in so you should be able to remove it with the transmission together same thing happened to me

Noises are hard to diagnose without hearing them. Does the noise change at any time? Certain gears, clutch engaged, dis-engaged, moving, sitting still? Need as many specifics as possible.

Have not a clue. Don't recall them coming in the small parts kit that comes with a bearings, seals and synchro kit either. Been a while since I have had one in here. You will probably just have to get as close to the same measurements on the spring and then make your own detent. I was looking at the safety detent for the most common reviled black pew-pew mechanism. Wink,wink. Can't say it on here or will get flagged. As I recall I think it is pretty close. May take a little re-working.

Shouldn't have said reviled. Should have said vilified.

@@CurmudgeonTransmission Got it I will try that lol thanks buddy!

@@CurmudgeonTransmission hey man so I went with you're suggestion. I got a spring that will fit! But I was wondering do you recall if the little metal plunger that sits on top of the spring is it hollow or solid? Like does the plunger have a hole in the bottom of it that is supposed to fit over the spring or is it flat and just sits on top of the spring??

It is solid and sits on top of the spring.

That is usually the input bearing. What brand was it? Also check the input and counter gear.

@@CurmudgeonTransmission I used USA gear bearing kit. Should I get a gm genuine ? I also get a shudder when engaging the clutch. Is that caused by the flywheel? Would that shudder cause the input bearing to go bad? Because it shakes really bad sometimes

Have had a few problems with them. Sounds like the flywheel needs to be resurfaced and the clutch assembly needs to be replaced. That can put a lot of stress on everything. Make sure the pilot bearing is good also.

The hub and bearing have to be pressed on. Popping out of gear would be something with the synchro, slider and hub on backwards, shift rail or fork.

@@CurmudgeonTransmission well, when I rebuilt it I put on a new 5th gear, new synchro, new slider, and new fork. And it doesn't have a problem going into or staying in any other gear, just 5th. Also which way do the two little lines on the slider face, towards the front or the tail of the trans?

Towards the front.

You are not going to know what you got till it's opened up but it sounds like the shift fork might be broken. But it will have to be taken out and apart.

@@CurmudgeonTransmission ended up swapping in a rebuilt NV3500. if you want this old one, can send it to you if you cover shipping costs. not sure what to do with it, its just sitting out back

Thanks for the offer but I don't really have a need for it. Hardly ever get them in.

Thank you. It's not so bad if you didn't have to stick it in the case without the tool. A lot of transmissions are in multiple platforms now. Sometimes it makes things more difficult as there will be slight differences between them. They seem to be a pretty dependable transmission. Retirement? What is this thing you speak of? I have been asked where I am many times, sorry I don't give that out, me and the wife decided that when I started this. Just passing along what I have learned, besides it is not my shop I just work there. Thanks for watching.

@@CurmudgeonTransmission Thanks for the reply ! You know we all dream of the big “R” still two decades away lol. No worries on location. I thought you had a business and if you had been near NC I was going to get you to price it . Thanks again !

@@PWL1371 Don't know anyone there, closest I know of a good guy is in Murfreesborough Tennessee, still a ways away. Go to ATRA website, Automatic Transmission Rebuilders Association, they will have a shop locator give you at least a recommended shop by them. www.atra.com/

It can cause a lot of damage. If the moon shaped piece has not fallen out of place you can just put a bolt back in. If it has you will need to pull the bellhousing off and put it back in place.

thank

@@marcobertolino7738 You're welcome.

@@CurmudgeonTransmission hello it is possible to have the measures of the bolt that I am missing, pitch, diameter, length. thanks, see you soon

@@marcobertolino7738 I don't have one here that I can get that info for you, but if memory serves me it is 8x1.25 threads and around 3-3 1/2 inches long. Only about 1 1/2 inches is threaded but it would not matter if it had more.. As long as it threads into that shaft about 1 inch you should be good. Make sure it is not coming out the other side of the shaft.

It will have bearings, seals and synchronizers. I believe we got it from Transtar.

@@CurmudgeonTransmission okay. What's that one part called that goes into the 3rd gear I believe. That's about say 3/8 thick and goes just about in the middle of the shaft into that hole? It's two peace, Well placed in than the ring goes over it to hold it in place so doesn't fall out.

@@zacharydavis4341 Retaining ring. Dodge part #4741288

@@CurmudgeonTransmission are the nv3500 synchro rings all one piece?

There are 2 different versions of the 1st and 2nd synchro's. 1 piece and 3 pieces.

With a press.You really need a press to take this apart and put it together. I don't have any way to mount a camera out there so I was not able to show that part.

@@CurmudgeonTransmission Would you be willing to provide an email where I can shoot you some questions? Kinda stuck on my nv3500 rebuild

@@ottoa.696 You can go to my Instagram and I can answer them there.

@@CurmudgeonTransmission What is your instagram ?

@@ottoa.696 curmudgeontransmission

We buy our standard parts from either Transtar or we have a local place called Wades. All else fails, the dealer. If you have a problem with only one gear it will be with that gear and not the fork or it would affect two gears. Be looking closely at the slider, synchro and gear.

Got my parts from Zumbrota Gear.

Sounds like the Synchronizer , Best check the fluid and over fill them by a pint or so.

Thanks guys for the tips and the places to go get the parts

It's possible, they are both 3500's. You will just have to open them both up and count teeth and make sure the synchro assemblies are the same. There are 3 piece and 1 piece designs.

Thanks buddy I'll hopefully get it done in next few weeks it's Ben to cold an snow now to do much with it I'll try an hit you up wen I get to it tho if I have any questions on it tho thanks for the reply back

@@chrisstevens1401 Ah man, you haven't had no fun till you put a fuel pump on your dad's truck outside @ 3:30 in the morning in the middle of an ice storm so he can go to work. Lol, hope it works out for you.

Yeah I've worked on a lot of vehicles in the snow an mud over the years I can rebuild some automatic transmission just naver did a standard one yet an not in a big herry to do it in the snow an cold right now lol

@@chrisstevens1401 I hear you, don't blame you.

Yeah. Money has wings and seems to always fly away. My plans were to retire 2 years ago.

If you are talking about the detent and spring I guess it got edited out. Plunger goes in first then the spring then the plug.

Your noisy

Thank you. There are 5 different kits depending on your application. You will just need to call them and give your information.

Not that I am aware of.

What are you having trouble with?

@Curmudgeon Transmission I used your video and I pressed what you did and applied the snap rings and things and my gears will not turn It just stalls the vehicle also I out the detent ball and spring in but with the clutch in and truck running the shifter falls out of gear I'm wondering is there also another detent set behind the detent plug or not stuff kind of fell out as I took it apart

Sounds like it is stuck in 2 gears at once. You have definitely done something wrong in the detent section of the transmission. You will need to take it back apart and look at it.

So I took it back apart and the only 2 things I noticed are 3rd gear doesn't spin on the shaft and when I press the synchro for 5th and reverse to add the snap ring those 2 gears don't spin either

I know I replied to this question but my reply is not showing up so I will do it again. If it shows up twice I am sorry. There are two versions of this, one has 1 piece synchro's and the other 3 piece on 1st and 2nd gears. They do not specify a split in years so it appears they are available in all. This one is the single synchro.

@@CurmudgeonTransmission Thanks. I was asking cause I was expecting the transmission in my 1990 Silverado to be a getrag 290 but it looks like the nv3500 you are working on in the video. I have a second 5 speed and it is a getrag 290 but it had a mystery piece in the bell housing when I separated the case. Kind of looks like it would go near the reverse idler but I don’t see where it would go. It appears to be missing a set screw as well. I have to order the kit for the nv3500. Thanks again for the response

@William Sobers No problem. There 3 other versions that look similar but are different. The NV3500 has the single shift rail the others have 4. There is a MG290, HM290 and 5LM60. The NV3500 came out in 93. Your's should be a 5LM60, early version.

@@CurmudgeonTransmission I understand all that. The transmission has shift rails like the nv3500 in your video. My other transmission looks exactly like the getrag 290 in your other video. I figure the transmission has been replaced at some point. The truck is 31 years old and I am not the original owner. The clutch is an older high performance type but is need of replacing.

Must have been swapped out. If you have Instagram go to my page and post a picture of what you are talking about and I will see if I can tell you where it goes. curmudgeontransmission
