Looking for info on G56 6spd

[GColeman]

I may need to move up to a 3500 and am considering a 6spd this time since I am towing more frequently than I had originally planned. I am looking for first impressions from any G56 users. Good or bad, I just want your opinions. Thanks.

I stopped by my local dealer to drive one..... They had fourteen 05's, thirteen auto's and one NV5600. Do people not shift their own gears anymore

It is next to impossible to find a 6 speed in NY. That is why I ordered my truck. In fact I had to order the 6 speed without ever driving one in the Ram. I could only test the autos. To answer your question, ask tomegun. I think he has driven one.

 

[JCleary]

I stopped in to a local dealer and asked if they had one. The manager did a locate, only to find ONE truck in IDAHO!!!



Unbelieveable. I don't understand why they're so rare. DC dealers must sell every one they get no problem. The dealers should order more.

 

[nickleinonen]

when i ordered my 04, the dealer had never even seen/ordered a manual trans in a pickup truck. . they thought i was crazy to spend $$$ on a manual when i could get the slushbox for only like $100 more in price

GColeman, if you come to May Madness, you can try out some 6 speeds. The dealers in Vegas should have them, and the dealer in Pahrump has a "wing-ding" for us Wednesday evening. He should have several.

My 2005 is due in to the dealer next week. I was talking to the sales manager, last week, and he told me that my 6 speed G-56 will be the first one the dealer has seen. I believe him, because when I was looking for one to test drive (NV5600) back in January, he had only one on the lot. He literally had a dozen 3500's, all with autos. I can understand people not wanting to shift, but why buy a 3500, if you want to tow heavy, and put a transmission in it that has had problems and still isn't certified for a factory exhaust brake?

 

[QWaller]

Interesting. Here in Montana, it can be hard to come by an auto. People up here prefer the standard I guess for the hills? Iwould guestimate that on a lot with 40 trucks, you would have 5-10 autos

It doesn't look like there are many (if any) new 6 spds on the road. May Madness may be the best for checking one out. Can you give me the dates and location? I might be able to make it. Thanks.

Looking for info??? Well check here, this should tell you what MB thinks of their 6 speed transmissions. They will not even install the G56 transmission in anything above a 4 cyl. 500 lb. ft. engine.



Also check this site and click on the FAQ's. Scroll down to the

"A: Check our dual mass flywheel page - it has a wealth of info on diagnosing dual mass problems and/or eliminating the dual mass as a source of problems. " section and click on the hot link. It will give you a nice education on the Dual Mass Flywheel ... then you can make up your mind if you want one of these potential disasters or not.

Having a 2005 on order, with a G-56, I take an interest in post concerning this issue. I looked at both your references, and I still don't see where it says the G-56 is inadequate for our CTD's. You reference information from MB and I guess make the connection that if they don't put it in some of their vehicles, it must be defective of not up to the task. Then I look at your second reference and see that it must refer to Ford and Chevy DMF's as the Dodge one hasn't been out that long. Then I look at your signature and see you have a 1st gen CTD and have put in a southbend clutch, TST plates, new injectors, a PDR HX40, among other things. Apparently you didn't like the way your 1997 came equipped.



I really like the TDR as it is a wealth of information. I appreciate most of the comments as they have been helpful while I owned my 2001. What is really useful are post from those who have first hand experience with an issue.



So what would you like me to do with your inputs. Cancel my 2005, buy back my 2001, or get a 1997 CTD to modify???

Look at an automatic ... the dual mass flywheel setup has a bad record.

Also, if MB won't put the G56 behind their Inline 6 cyl. which has less HP/TQ then the ISB ... doesn't that say something?

My clutch had to be replaced because it detonated on the first test with the mods I had (supposedly over 800 lb ft. ). The stock clutch was good for moderate mods. The spces of the G56 tend to lead one to believe that they will fail behind a stock ISB.

 

[DDahl]

Preliminary info (low torque ratings) on the G56 caused me to rush out and buy a 2005 with the NV5600. Time will tell if it was a good decision. DC low balled the 600's emission technology to save a buck at the expense of 600-610 mpg. I hope the same is not true for the change in 6 speeds!

 

[Joseph Donnelly]

I disagree that the emissions strategy was lowballed. It was higher balled than the competition that had to use egr and a cat. The cat takes care of hydrocarbons including some soot. Retarded timing helps with nitrogen oxides, as does the egr system. Egr is worse, imho, than timing changes. You can add a box to bring up the timing for better mpg, but the egr is tougher to work around and hurts mpg more.

 

[klenger]

I find it interesting that the G56 has been declared a POS, and other than Tommygun, no one has even driven one yet. :-{}



I would not base too many decisions on what might be published on the MB website. Vendor websites are riddled with incorrect information (www.dodge.com). Also, it's possible that MB beefed up the G56 and has not updated the website. We do know that the NV5600 was (is) a great transmission. We don't know much at all about the G56 yet.

 

[Bloomy]

I guess my thoughts are similiar to klenger. I saw the shifter for the first G56 tomeygun had on his lot so that makes me an expert right? Anyway, taking a transmission's max torque rating for the gospel has been dispelled as myth in a few circumstances. Such as my NV4500. Max torque rating is in the 400's somewhere (didn't want to look up the exact number). I have somewhere in, around, or over 1000 lb-ft torque. That is at 200,000 miles with the last 60,000 miles at that power level. So if we were to consider the max torque rating then my transmission should have died a long time ago. No problems, no repairs, fifth gear hasn't even been replaced yet and I do a lot of towing. Lucky? Anyway if you want the G56, then get it. I will take a new manual over the auto anyday. If the dual mass flywheel becomes a problem, I am sure Peter will have something available before to long. And until then you still have a warranty. Maybe Luk has gotten the dual mass right the third time around with the G56??



Thomas



oh, the NV 5600's torque rating has been exceeded many times over as well with few failures that I have seen or heard.

Are you serious? Someone asked for information, and the man gave some. I'm sure FATCAT doesn't want you to do anything, just read the info and make your own damn decision. Why jump on the guy? There's nothing to gain if you take everything personal. Not one person on this thread has first hand experience with this transmission because it's so new. Take a chill pill...

You might want to check out the most recent issue of Diesel Progress: John Deere is using a dual emission strategy (high and low end). Cummins appears to be also. All Cummins current and proposed on-road emission technology (except Dodge) involves egr and vgt, because they state that it provides the highest performance and best efficiency. Their off road technology makes use of multiple injection events without egr or vgt, because (as John Deere says) the initial cost is more critical than maximum performance and economy. Cummins brags of its efficiency for its on-road strategy but doesn't mention efficiency with its off-road strategy (as found in the 600/610).



Moreover, Cummins has two interesting papers: One on on-road emission strategy and the other on off-road emission strategy (found on their web site). It serves as interesting and informative reading. It becomes obvious which strategy was used in the 600/610.

 

[FATCAT]

My responses were to RCollman ... I did not know that RJOL had a new truck on order. Sorry to give you that (Oh Dam I think I did something I shouldn't of) feeling.

Do a Google search on "Dual Mass Flywheel" problems and you will see people cursing them from sports cars to trucks. Many have replaced them to single mass just to reduce the maintenance cost and add reliablility and allow them to add power.



I wish you luck in your new purchase ... but just empty your spare change every day into the "new flywheel" fund.

When someone, who doesn't own a 3rd gen, and has no first hand knowledge of this setup, comes to the forum, quotes a couple of articles that may or may not have anything to do with the new G-56 and the DMF setup in the 2005 CTD, and then sums it up by saying:



"It will give you a nice education on the Dual Mass Flywheel ... then you can make up your mind if you want one of these potential disasters or not. "



What do you expect us poor 2005 buyers to say... "Thanks for all the info??"



Now show me anywhere in this thread that someone asked his opinion about the suitability/durability of this setup...
