I think the low revving stock spring had a fair bit to do with many 'rags biting it earlier rather than later. Especially with a load on, the operator has no choice but to lug the heck out of the tranny, which is where the getrag really falls apart, literally and figuratively! I can shift a lot faster and smoother if the engine is wound up past 2900.

 

My truck is 3.55 geared.

I don't notice the 2nd to 3rd difference nearly as much as the difference between 3rd and 4th.

I could use a gear right between 3rd and 4th.

I have a fix for it, laying in the floor, a Dana-Spicer 4-speed auxilliary with double-under, under, direct, and over-drive.

I just need to get the nerve to remove an offending cross-member, build a new cross-member for the auxilliary, and splice some drive-shafts.

I guess it will be my next major truck project.

 

Due you thing that the gear ratio's were changed be tween the first getrag and the last?

I was watching my tac will going the work and theres a 1000 rpm between 2nt and 3d and all the rest of less then 1000..... that is, shifting a 2000 rpm.
3d to 4th was still 8 or 900 and all the rest was about 500 rpm.....That was with outusing my Gear Vender Overdrive!

My buddy has a sec gen and buyed it with bad tranny, got it form a tranny shop and was sold a cheeper one cause it was out of a ferd?
His 3nt to 4d is so far apart that theses no going backup to 4th until the hill is dun even with a light load!

 

That's why I like the NV4500. It's spacing is perfect as it should be. Some dudes ratted me out to my wife that I drive my truck like a sports car! Couldn't do that with the raggie....

 

that just it, it is a NV4500, it's just out of a ford truck!(Gear ratio's are diff)

I couldn't tell the diff between the two tho so how would you know if you got the close ratio (dodge) or the not so close ratio, tell you installed it? atlest the tranny shop told him that is was out of a ford and the ratio's were different!

 

I don't like the 3rd to 4th jump of the NV4500 either. Now if somebody could come up with a way to put the new Mercedees Benz G56 in my first gen, I'd do that in a second(if I could find a tranny cheap enough), cause I love that tranny. No bearing growl like either of the NV or rag.

 

A...if you'r talking a but the 05.5 and 06s thay are a getrag, 6sp, and the fill of the shift is just like our getrags like the fill of the nv4500(5spd) and nv5600(6spd)better!! just my .02

 

Ford never used a NV4500, they always, and still do use ZF manual Transmissions. GM used a lighter version of the NV4500 in some of there gas powered 3/4 and one ton trucks in the later 90's up until recently.

 

No sir, it is not. That is a common misconception because they call it a "G56" everyone assumes it is a getrag. I am a dealer you see, and just today I was helping in the parts department, and when you look up manual transmissions for an 05' Dodge with a diesel engine it gives you two options on the screen, the old NVG5600, or the new Mercedees Benz G56 6-speed manual, it specifically says "Mercedees Benz". And I personally like the shift feel of the G56 way better than the older and more crude NV transmission's. I have owned and run both, and currently have a G56. The big thing I like is the total lack of bearing growl in the G56. The NVG transmission's had bearing growl even when they were brand new in certain gears at low rpm's, the G56 does not.

 

That's the 1st I have heard of the Mercedes manual. Is it tough? Are the ratio's evenly spaced? If the G56 is at least as stout as the NV4500 I'd be interested.

As far as the gear rattle, my NV4500 doesn't rattle unless I am driving improperly by lugging the engine, and at that point I think everything in the drive train is rattling because of the harmonics from the engine pulse.

 

So far really tough, I've had a couple and I have a lot of customers out there beating on them in commercial service and have not and any problems or failure's to date, and I have sold a pile of them. Dodge diesel pick-ups with manual transmissions are about 80% of our sales business, so I see a lot of them and the problems if they have any.

 

Ho was the manifacure of the getrag???? I thing it was german.
I could be wrong about it, being getrag but the shifter shore fills like one.


I agree that there hasn't been any failers but, it only a couple years old
only,... time will tell!

I do like the close ratio. is probly the best tranny out there yet for that.

I talked to my friend and he repeted what i said previusly. It is a NV4500! i'm shore that it wasn't a diesel tranny but a gas one that had the larger input shaft put into it.
Have no way to prove it eather way just repeating what the tranny shop said to him.

 

I got this right off of standard transmission and gear's website.

Ford ZF Transmissions & Parts




"In late 1987, Ford introduced the 5speed ZF transmission in the F250, F350, & F450 trucks. They were available for gas as well as diesel models. The easiest way to identify the unit is to see that it has power take off (pto) opening plates on the lower sides of the unit. ZF transmissions are reliable units that should provide good service when taken care of properly. Keep in mind that the ZF has 6 constant mesh mainshaft gears, so there is a considerable amount of potential for heat buildup. It is never a good idea to leave the truck idling with a pto engaged, such as in tow truck applications. The unit was redesigned in '96 and had small, but significant changes. The synchro teeth were enlarged to provide longer life and more positive shifts, and the bearing retainer was designed to be replaced without having to disassemble the case. The case was beefed up also with this design.
These units are prone to be a little noisy, and noise issues comprise most of the complaints we hear. Please do not remove your transmission if noise is a problem. Check all the components of your drivetrain carefully first. Things like injectors, dual mass flywheels, or even differential problems can cause a noise to come through the unit. Before we tear a unit down with a noise complaint, we make sure that we have done our best to eliminate the possibility of something else as a the source of the noise.

If you have determined that a transmission is needed, we can help. We can rebuild your unit or sell you a reman from our stock. We also sell factory remans & new units. To get the right transmission, we will need ALL the numbers from the tag on the side. If the tag is missing, we will need all vehicle info including VIN to get you the right unit. As a BALLPARK figure, a factory reman sells for $2250.00, a new unit sells for $2750.00, & the core charge is $500.00(refundable). The core MUST be completely assembled & have the shifter stub still on it. Shipping & handling can be quoted with a zip code and is normally about $175.00 in the 48 states.
We also sell a wide range of parts for the ZF, so if you decide to tackle one of these beasts yourself, let us have the parts list & we'll get right on a quote for you. If you need more info, call us at 1-800/ 783-8726, or email us from this link.

Soon to be available!!!

ZF parts for the new six speed! Call or write for more info!!"

 

Ya, went looking around there for a bit....Good sight!!!
Maybe it was a chebby

Not to bad of a price, for the NV4500
