NV5600 Dodge rebuild?

[DGamelin]

Does anybody know who does the rebuild on the dodge rebuilt trans. The there year warranty sounds good. I wounder what kind of work they do?





93 250 2wd xc 354 auto 262k miles

04. 5 3500 4wd cc dully 373 6speed 85k miles

I have no idea but I'm sure it would be a good job. It would, however, be pretty likely to be quite expensive.

I had personal experience with Standard in Ft. Worth back in early 2006. They did a professional quality rebuild for me at a very reasonable price.

More then likely it is Blumenthals out of OKC. They are (were?) the Chrysler North American rebuild center for the 5600.

Sixth gear went on mine a week ago. A local shop had the best price on a rebuilt from a place that he has had good results. After a freight fiasco I finally get the transmission. I pulled the PTO covers to install my Fast Coolers and the first thing I see is a gear tooth with a divot in it. I have to wait until Monday AM to see what will be done about it. I am thinking to go with the Chrysler reman for the warranty. I don't think I want another one from the same place because if this is the kind of work they do where it is obvious what have they done where you can't see? I want to find out if the warranty is good for Canada and USA and if it includes labor. I would have gone with Standard or Blumenthal but frieght and border logistics put a damper on it. I really wish that some one would make a transmission for towing. We have the best engine in a pickup for towing but no drive train to back it.

There's not much point in having these engines if the trans can handel it.



I am surprised that some one hasn't figured out how to put an eaton, fuller, or spicer in one yet. I don't know if they make one small enough to fit.



Is the G56 in the 06 holding up any better? It looks to be geared better for pulling. And what kind of headache would it be to change over?



I have a customer with a 01 nv5600 over 500k on it. He pulls loads you wouldn't believe. He hauls 23 round bales of hay at a time (the big ones) on a 8500lbs trailer. He got caught in the rain once, blew the center of a dully wheel out. When he went across the scale over 25k on the trailer axles alone. He has 354 gears he never uses 6th gear when hauling the trans has never been touched. He adds lucas oil treatment and fills to the stock leave. He has only replaced the clutch once. He does this about every two weeks, 400 to 500 mile trips one way. Usually loaded with something on the way back. He sells that organic hay. The truck is so tired that the time he pulled in here for the blown rim, the truck started thumping backwards down slight incline our parking lot has, the engine wouldn't hold it. Now is this the ideal combination? Or the fact that his truck had less power to begin with when new on a 01 and at 500k most in 5th the engine is so tired, is that helping to make it last?



I am having a hard time even going out to fix my truck knowing it's not going hold up anyway.

 

[HBarlow]

I didn't find mine that bad. I had a little over 302k miles on my '01 HO/6spd when it became noisy. I pulled a lot with it, I was transporting with it, but not much at over the factory gross combined weight limit.

Granted the NV-5600 is not as good as one of the Spicer or Eaton "real truck" units but that was all that was available at the time.

 

[Slow Six]

The rebuilt went back this AM. I have a Chrysler Reman ordered and should be here Wed. AM. It is more money but the warranty was the deciding factor for me plus availablity.

We've used Jasper engine and transmission in the past for service... (Ford engines)

Jasper Transmissions

They belong to one of associations we belong to and I've sat at meetings with their guys... seem to be very professional people... someone I'd use...

WOW, this is good news about the NV5600, only one clutch job in 500K and the trans has not been worked on. He must be a good operator of the clutch pedal. This gives me hope with my truck, at 134,000 miles now, still all working good.

 

[DGamelin]

Slow Six, let me know what you think of that trans.



Turbo Bob, I will try to put some pictures on when I get back, got to make a run with the old dog. He is one of my favirote customers you never know what he will have on that trailer next. #ad

 

[Slow Six]

Ok. I don't get it until Wednesday AM. I hope to have it in that afternoon. I should be towing with it by the weekend.

On another forum I am on, a guy put a roadranger 10speed in a 3rd gen. If you are interested I can post some links to it.

what happened that you lost 6th, did it go out totally? My 6th gear is knocking really bad when I am on the throttle, it quits immediately after I let off the throttle, but it shifts in and out of 6th fine.

 

[Slow Six]

Kinda sounds like mine did. When I removed the Fast Coolers there was a chunk of gear tooth in each one. The transmission worked good in the bottom five gears so I went tne remaining 50 miles home in fifth. It would shift in and out of 6th no problem but once power was applied the noise and vibration would come on. I looked into the transmission through the pto hole and the bottom gear had the most of 2 teeth gone and it also looked like the top gear was missing teeth as well. Other than the pieces in the coolers the magnet had a fairly normal amount of material on it. When I did the first oil change on this one there were some abnormal pieces in the bottom and I have always wondered where they came from and was this the beginning of the break down. I am turned up and I have towed hard in sixth. I tend to drive it like the our big rigs but it looks like I'll have to change my ways. I have a problem with high rpms but these newer engines are different. When I was talking to the parts man today I was told that to maintain the warranty on my reman I need to use an oil that has the MS-9224 spec on it . The Redline MTL does not have this spec so I will try to return it and I'll use the Mopar MTL. This has also got me to asking if the Redline MTL contributed to this failure. It shifted better with the Redline but it may not of cushioned the gears as well. A lot of things to mull over. My reman should be here tomorrow and hopefully I'll get installed by evening.

 

[TWhetten]

well I guess I will pull my pto covers off and see if I can see anything

 

[tkerrigan]

Yes, use fifth when pulling hard for any length of time. The torque goes straight through the center of the transmission using the main shaft. Using sixth gear, the rotation is transferred to another shaft, then back to the main shaft. The shafts are trying to push each other apart, quite hard at high loads. That puts high load on the bearings for the shaft, one of those goes out, there goes sixth gear, etc.

 

[RVTRKN]

Tom, what about pulling on flat lands at 21K GCVW? Normal for me is 70MPH when outside of California, and 60MPH when in California, But I always run in 5th, or 4th if I need to, when pulling grades of any degree.

 

[tkerrigan]

I do the same thing except hanging more at 60MPH for fuel mileage.

 

[TWhetten]

well I pulled the passenger side pto cover off and sure enough there were a couple teeth missing off the big gear toward the back of the transmission. I have no idea how I did that because I wasnt towing and I was driving easy when all the trouble started.

That's a really good point, thank you for posting it.
On edit: wait, is this accurate? It's not quite clear to me from the service manual drawings. Doesn't every forward gear run through the countershaft?

I thought I read elsewhere here that when towing at maximum (or above) the transmission should be operated in 5th.
