G56 Disappointment -- 1st time posting -- maybe not the G56 after all?

Hi all. Long time reader / first time posting. The information I read here is excellent and I find most of the posts / suggestions / observations are very similar to my experiences.



I've bought new and owned a 96 4x2 5 speed CTD, 97 4x4 5 speed CTD and a 2004. 5 4x4 CTD Auto. I've loved them all. Other than paint trouble on the 96, I never had a complaint on all 3 trucks. Even the 2002 PT Cruiser I bought new had zero defects and excellent build quality. The build quality on these Dodge Ram Trucks seems to be great.



But the events of the past month have challenged my views... .



Let me start at the beginning.....



I missed having the manual transmission on this 2004. 5 like I had on the 96 and 97 trucks I had several years back. It became evident to me that I made a mistake buying the 2004. 5 with the auto in the spring of 2004 -- not that there was anything wrong with it -- it just wasn't for me. So I traded the 2004. 5 Auto for a 2005 2500 4x4 Quad Cab Short Bed 6 speed Thunder Road which I ordered on Feb 22nd from the same dealer. They're 240 miles away from my home and I'm friends with my salesman.



After the vehicle was held up in storage for 5 weeks for some mysteriously unknown reason to me at the time (now known as the infamous G56 "hold"), it finally arrived at the end of May.



I test drove the truck (drive it 15 miles and took it over 70 mph) and all appeared to be fine and then took delivery late last month.



By the end of the 240 mile return trip the same day I was beginning to see problems as listed below in reverse order of severity. The first two are relatively minor and the 3rd is the biggie for me:



1) The throws of the gear shift seem to have to "pierce through" a series of resistent notches as you go through some of the gears. Going from 4th to 5th is particularly difficult and actually can begin to make your palm sore.



2) 6th gear on my transmission groans when there is negative tension on the driveline. Basically, you can hear it anytime you take your foot off the accelerator in 6th gear.



Here is the big problem and the primary basis for my dissatisfaction:



3) There is so much driveline slack with this configuration that you simply can't shift gears without constant clunking. I'm not talking about mild clunking -- I'm talking about clunking that reverberates through the floorboards. The only way to avoid this is to be sure to "float" the rpm's between shifts -- i. e. make darn sure you keep your foot on the accelerator between shifts, but not too much, so as to assure that you keep positive tension on the driveline at all times as you shift through the gears. Basically, if you have any change in tension on the driveline, you'll have a major clunk. This slack does not seem to be coming from the rear end or the U joints. It's coming from the floorboards / shifter area.



Please understand that this is my 3rd CTD w/manual transmission (and 4th overall) in the last 10 years. I'm an avid fan of these vehicles and like the "raw nature" of the CTD powerplant. I know what these are and know what to expect. I also understand that it's not realistic to expect it to shift like a BMW M3. But this driveline feels like something you'd expect from a U-Haul truck with 250k miles.



My feeling is that these are light trucks -- not midrage European Mercedes BOX Trucks with 30k GVW ratings. These are built for the American Market and sold as LIGHT trucks. I think that DC has made a huge error with the G56 and has gone backwards 30 years in NVH evolution (Noise / Vibration / Harshness) by implementing the G56 on a non-commercial grade 3/4 ton light truck. I couldn't in good conscience recommend ANYONE purchase a G56. Additionally, I would not feel comfortable towing anything of significant weight with this driveline slop.



So where does this leave me? I took the truck into my local dealership for service. This Dodge dealer is owned by the same parent corporation (AutoNation) as my selling dealer 240 miles away. On my appointment date, I took the service advisor AND a non-transmission mechanic (he was the only one free at the time) for a drive and demonstrated the clunk / slack and 6th gear moaning under decel. They both heard / felt the issues and sympathized. This was good -- a sanity check for me of sorts. I'm not one to spend time in service departments. (If there are minor problems with a new vehicle I often chalk them up to character flaws... . I even ended up accepting the peeling paint on the 1996 without a repaint. The peeling in the door jams and above the headlights was not severe enough to demand a repaint in my opinion. So I don't expect perfection. )



Back to 2005 -- So the service advisor wrote up the complains with the typical "See Me" for an explanation if the "driveline specialist / transmission guy" had any questions. The next day the service advisor called to tell me that the technician reported that there was nothing wrong even though the service advisor experienced the problems the day before when I dropped the truck off. He reported that the "driveline specialist / transmission guy" said that this level of slack and noise is normal for this new G56 transmission. Not knowing what to do, I went up to the dealer to discuss my concerns and dissatisfaction with the service manager. The service manager tried to pacify me by telling me I had such good taste in how I ordered the truck, how nice it was and how tough the G56 was -- essentially changing the subject. Essentially tried to make me like the truck with this unsatisfactory attribute. Bottom line is that his position is that driveline slack to this extent is normal for these G56 based trucks. They had no other G56 trucks on the lot to test with and there were no more on order or on the way to test drive.



I called the DC Customer assistance center and requested they have the service department manager get the DC district manager review the vehicle. After they called him, he called me back -- not too happy -- and now after a two week wait, the appointment has been set for 6/29/05 to have a DC district manager evaluate the truck.



I guess I'm writing this for two purposes -- the first is very selfish -- to vent about my frustrations and dissatisfaction -- and the second is to help others by asking them to please be sure to test drive a G56 truck that has over 300 miles before you buy one. How one can do that I don't know for sure as it's not a practical thing to try to do. But I don't believe that I experienced the driveline slack during my test drive before taking delivery and making the 240 mile trip home.



I'm still a DC and a CTD fan and think I always will be. These are unique and awesome trucks. I'm just so sorry that DC has decided to go away from the NV series manuals IF the G56 is the basis for this ridiculous amount of driveline slack.



Sorry for the long-winded nature of this post. I'm grateful to have a place to commiserate with fellow CTD fanatics. I appreciate any and all thoughts and promise to report back what the DC district manager has to say.



Thanks guys.....

First suggestion is go find another G-56 equipped truck and see if it does the same thing. I picked mine up yesterday, had 300 miles on it when I got to work this morning, and I am not experience ing any of the same thigns you mentioned. I had the opportunity to drive a NV5600 and G-56 back to back and felt the G-56 shifted much smoother. The one thing I have noticed is that the 5-6 thrown is not straight, but after one day of driving I have that down pretty well. Try another truck so you know it is a problem with yours, then make them replace the transmission or the truck.
 
I have a 2003 w/ the 5600 and i am annoyed at the driveline slack in it as well. I feel no matter what i do, i can't shift it smoothly. I wish i had gotten an auto. Good luck.
 
I have a 2003 manual that seems to have a fair bit of driveline slack, but it doesn't bother me that much. I just figured it was normal.
 
Just drove a G-56 for the first time, today. Wanted to compare it to my '03, NV-5600.

It seemed to be a little less notchy than my 6-sp. The one thing I did notice, though, was the clutch seemed quite "grabby" and engaged very quickly, right off the floor. Felt like I was just learning to drive a stick shift for the first time. However, this is nothing you couldn't learn to operate smoothly.

I'm, also, wondering if the DM flywheel isn't causing the problem you are noticing. I did not notice it on the truck i drove, though. It only had 24 miles on it.



Good Luck.

I have always noticed in both of my NV5600 trucks that if you don't shift it just right, you get a slight clunk. I have gotten used to it and can usually shift it rather smooth. So it doesn't bother me any more.
 
G 56 transmission

I now have 1400 miles on mine, I got it 3 weeks ago after having a 04. 5 auto that the dealer/dc wouldn't fix but thats a whole other story.

I love this truck the clutch feels nice, although like previously mentioned it did have a different engagement point but that was easy to get used to.

The shifting is very smooth and the driveline has no clunking or vibrations like my last truck did.

Overall I'm extremely happy with this truck and I'm already over 17MPG.

I would definitley go to another dealer, and if the rep doesn't agree with you again go another dealer in a different area to get a different rep.

I'm now in a battle with DC and their complete disregard for customer satisfaction, I spent over 6 months trying to get my old truck fixed with a total of 6 weeks out of service and the dealer/rep telling me it was fixed which it was not, finally I spent $10K to get the truck replaced and I'm taking the dealer and DC to court.

I wish you luck in you dealings with your problems, Like I said mine drives great, sorry for your problems.

Good luck and keep us posted.
 
if the diff has a little bit too much backlash, it will multiply the feel of the driveline play when rolling as it needs to speed up to make pinion to ring contact in the differential... i too also started to think about the DMF being an issue as anything that allows some movement is going to make the driveline play feel bigger. . my 5600 too has some driveline play but it's not so bad i feel... if i don't shift it just right the truck will let me know, but i can [usually] get through the gears quick enough to not have the engine rpm drop below what the next gears engine speed should be
 
I'm thinking with all the NV5600 6 speed replies -- seems this is more common than I thought. Now I'm wondering if it's the 4x4 transfer case in later models and not the fault of the G56 at all. If this is the case, I'll get off blaming the G56 (even though the dealer thought it was normal for this 'new' transmission) and look to other possibilities... .



Are there lots of folks with a 2003 or newer two wheel drive 6 speed with with a lot of slack?



The best part of all this is hearing that you all know what I'm talking about. So if the end result is that this is normal for this configuration, I'll believe that result because so many of you all have experienced it too and hear what I'm saying.



As a side note -- I love the truck regardless of the clunk clunk clunk. It's really one baaaaaad / gorgeous rig.



Hey guys! Thanks for all the replies!
 
Traction

I have noticed this on other peoples trucks I have driven.

Install a set of traction bars and that will take quite a bit of movement out of the drivetrain.

You will be impressed :) . Sam
 
How about 16. 7K miles of experience on my 04. 5 3500? Basically from day one I had the clunk. With this many miles I am pretty sure it is coming from the rear end. I have found the best work-around is to drive it like an old non-synchro with square gears. In other words, put in the clutch and get the engine adjusted to the right RPM before pulling into the next gear. It’s easy to learn on the 5600, you just pull against the next gear a little and it drops right in when the engine speed is correct. When doing this you will not hear the clunk. Now, if you do the same thing using the clutch you will also not hear the clunk.



There’s another way too. Power shift the *******!



What I have found is that I do not take my foot totally of the throttle when shifting. Let’s say I run it to 2K RPM and shift. I don’t want the engine to drop to 750 idle-speed when it should be at 1500 for the next gear. (Also makes you sound more like a big rig!) I also find that dropping the power just a bit before coming out of a gear reduces the over-run and makes controlling the engine speed easier for the next gear.



In summary, “This ain’t no PowerJoke”! It takes a little time to become a good CTD driver. They are also not the same as the Second Gen trucks. If you really want a challenge, drive an old 5-speed Toyota a few days a week. Then get into the CTD and try to figure out which gear to hit after slowing to 35 for a stoplight that just turned green! I’ve almost been tempted to let my wife drive a couple times!!!

Good luck to all…. Jay
 
Do like Jay 'sez, he's got a handle on it. The close ratio, big ole' 6-spd shifts different than the wide ratio 5-spd. The motor will slow down faster than you can shift the 6-spd, so you haft'a get the rpms back up a little as you let out the clutch. Also like Jay says, don't shift up, under full power, (i'm not saying you are) but if you do, the clutch will release before the motor backs out of it's power (electronic wire throtle pedal) and cause rough shift. It is also hard on the clutch as it will slip a hair as it releases and the power is still there.





"NICK"
 
You guys beat me to it, I was gonna suggest rolling out of the throttle a bit before a shift. Not enough for the RPMs to drop, but enough the let the engine defuel and not be under load. After the shift roll back into the throttle. Talk about a big rig sound :D



I've found that snapping your foot instantly from 1/2 throttle to zero throttle and from zero throttle instantly to 1/2 throttle while shift will not work at all. It'll work on a gasser and especially a sports car, but not on these heavy things.
 
Drive line backlash

Remember each gear has to have clearance in order for the rotating members to work together. All of this clearance is additive and plays out in the end as perceived driveline "play". This also includes the motor mounts and the transmission mount rubber bushings. The best way for you to see this for yourself is to take the hood off you truck, take it out on the highway, accelerate up to road speed, floor it and let off. You would be amazed at how much things move around out there when there's 610 Lb-ft of torque taking up the back lash in one direction and then being suddenly removed!!!! :eek: :eek: JGann, I hope that you get your truck fixed as your driveline play seems from your discussion to be excessive.
