Found A 08 For My Son QUESTIONS?

[macdaddy]

Need some help here gentlemen... ...



My oldest son has been looking for a truck for a couple of months now and found a 08 white dually at at a Dodge dealer here in So Cal.



We like sticks so it's a 2WD G56 truck 3. 73. 1 gearing. with 17K for 33K. It's clean.



Did some of the problems with the DMF on the G56's get better by 08?



Any other info would be great!!!!

He's a lucky Son, must be a good kid.



Teach him how to drive correctly.



Put trans in N and stop lights, pedal up, minimizes clutch pilot bearing wear and wear on clutch, bearing and hyd system.



It is not a hill holder, don't use the clutch as such!



1st gear or 2nd gear starts w/o a load with the engine at IDLE let the Cummins do it's job.



It's not a hot rod 4 speed, it doesn't shift like it, don't drive it like you wished it was a 4 speed.



Respect it's power and don't abuse it.



Good luck

He is a good kid. He's 23 works with me and just bought a house (nervous about him buying a truck). I'm very proud of him.



But after all he's a man and knows his finances. As for how to drive a stick and treat a clutch he's good to go, he's had a good teacher.



He's excited about it. Id like to hear more about the 08's. He's going to go and check it out this afternoon.

I have not read anything about any factory improvements to the clutch or dual mass flywheel assembly.

As far as I know the same system has been installed since late '05 when the G-56 replaced the NV-5600.

Whew.....

I was hoping to hear from you HB. I know you know your s&%t about these things. The truck looks really really good.



The kid has cash burning a hole in his pocket (scary). From what i've briefly read the 08's are ok?. Theres some time left on the 3 year 36k bumper to bumper, and the 5 year 100K on the motor is good to go.

Mac,

I have an 08 with the stick. Gary is right, its not a hot rod. Take off in second gear unloaded and use that exhaust brake all the time. Just got back from a trip to Columbia. 230 miles at up to 75 MPH and the overhead read 15. 6 MPG. Get the Carfax or the VIN # and see whats been done to the engine so far. It pulls like a friggin Electromotive freight train, quiet and powerful.

He Bought it!!!

Well he drove her home. It's a repo super clean. I will try to get some pics. White 2WD dually G56 SLT mud flaps. Frahm Dodge Norco Ca is where he got it. 17K miles. Lo Jak. Free oil changes for life as long as he takes it to them.



I guess it has been there for a while. Not many people want sticks here in So Cal. We work in the oil industry and only work 14 days a month. We really dont drive during traffic hours, hence the reason for wanting the stick.



I guess ill get him signed onto the TDR. MacDaddy JR or something

Congrats. Sounds like you picked him up a nice truck. Oo.

Mac,

I have only good things to say about the '08s. Mine has been perfect at just under 83,000 miles. Of course the C&C version that I own has less restrictive emissions equipment so my truck may not be a good example.

Some report zero problems on pickups with light duty cycles, a few others have reported soot issues with the EGR and turbo. I don't think anyone knows exactly why some set codes and others ignore dealer service departments.

It does seem likely that the ones that see more high speed highway use and more hauling or towing may exhibit fewer problems. The SoCal freeway system and long high speed commutes may be a good thing for reliablity on your son's truck.

I hope your son enjoys and appreciates his as much as I do mine. They are smooth, powerful, and quiet trucks capable of heavy towing without apparent effort.

Excellent Advice! That is the best summarized advice I've seen concerning a manual shift transmission truck!

Thanks HB... .

His commute is only 21 miles each way to work (freeway), so I think the truck will see some easy miles.

The trailer he will be hauling is a Hallmark Edge we share that weighs in at 7K loaded. Im sure this truck is a major improvement over the 1500 CC Hemi he had wore out.

Mac,

21 miles x two daily at 65 mph should be great for keeping the CELs turned off. That and occasional trailer pulls. I think the 5 mile commutes at 35 mph and lots of traffic lights is what causes the problems some have experienced.

Got To Drive It Today!!!!!!

Well I got to drive the my son's 08 today. Man this is a nice truck. I've never driven a 6. 7 let alone a G56. I have to tell you that the G56 feels real nice, compared to the NV5600. Any past troubles the G56 may have had I have to say it's a much better feeling transmission than mine.



I do have a couple of questions that im sure i'll get scolded for not already knowing.



*Are the turbo's on the 6. 7's variable pitch (no wastegate)?.



*Is the factory E Brake inside the turbo? (I cant find it).



Mac

 

[KLauber]

The turbo is the E brake. It uses a sliding mechanism to close it off during braking. I beleive the turbo is also variable pitch too which allows it to have the braking capability. Others with more technical knowledge will expand on this.

So where are the pics of the new truck Mac?

Ken

 

[HBarlow]

As KLauber wrote above, the turbocharger itself provides the exhaust braking function. It is a VGT "variable geometry turbo". Full throttle opens the orifice providing full boost, closed throttle provides closed nozzle and exhaust braking. A pretty ingenius device.

Thanks for the info HB, and Ken. Having an e brake myself (Pac) I have to ask does he need to leave it on all the time when empty. It really has a jerkey feeling when your doing stop and go. I left it off and drove it like I do mine and it seems to like it alot in stop and go.



Also does the regular driving at highway speeds (freeway). Help keep the turbo clean from EGR related issues?



Mac

 

[HBarlow]

We're all guessing, perhaps based on some knowledge and experience, that regular highway driving at cruise speed and towing will help prevent soot issues from occuring. Full time use of the exhaust brake function is also generally thought to be important.

The way I understand it, regular use of both full throttle load pulling or acceleration and closed throttle exhaust braking exercises the turbo through its full range of internal movement and reduces likelihood of soot buildup. This may be oversimplified but I believe it is generally accurate in principle.

Cab and chassis versions of the ISB6. 7 like mine are programmed to always activate the exhaust brake function unless the driver turns it off. Pickup versions are programmed the opposite way, requiring driver input each time the truck is started to activate the exhaust brake.

If I owned the pickup version I would alter the switch and wiring to always turn on the eb. A TDR member wrote about how he changed his a few months ago.

Here is a picture of a VGT slide ring. Both the intake and the exhaust housings are removed. :

Macdaddy, look at sig although its a C&C its close to what your son bought. Love it and would recommend it only for truck use, not a grocery getter.

 

[macdaddy]

I was able to run the VIN on my sons 08. He bought it from a dealer with 17K miles. White 3500 2WD dually G56.



*It's a Mexico truck with a build date of 08/17/07.

*Went into service on 09/29/07

*Clutch replaced at 5K?

*Looks like a women owned it.

*It had the H-34 recall performed for the dash shield.

*3:73's Anti Spin.



I think the owner may have been spooked by the early death of the clutch (who knows).



Also the previous owner would have owned it during the sky rocketing fuel prices, there by explaining the reason for the low milage. (guess).



I have been all over this truck top to bottom. There's no sign of it ever being used for any type of towing. No evidence of a fifth wheel hitch, no fresh paint on the factory reciever either. No sign of a hitch pin ever even being used. Grocery getter?
