New Getrag 6 speed transmission? Not what I've heard.

Is the dual mass flywheel a good thing or a bad thing?

My '05 has been on order for a month, so I'll be very curious to see which 6 speed I get... I'm hoping for the NV - fear of the unknown I guess.

both ford and chevy have had issues with them... i hope it doesn't become a problem for us

Searching the DaimlerChrysler site, I found something that may very well relieve some tension amongst those nervous about a new transmission.



The G56 is NOT a Getrag.



The G56 is built by DaimlerChrysler Commercial Vehicles Division (CVD, as mentioned in the pdf posted by Tomeygun). It was introduced 2 years ago in Europe and has been hooked to - surprise - the MBE900 diesel, so it should handle the ISB with no problem.



Here is the official photo from Sep 9 2002:

A couple of interesting thing about the picture are that it is using an interal (inside the bellhousing) slave cylinder and it is a side loader shifter.

The picture of the G56 6 speed in Petersen's 4WHEEL shows the G56 a Top Loader. The bell housing and main case are one piece with the clutch slave unit mounted on the out side.

lesson from my PSD days....

I would be more worried about this dual mass flywheel pos than the new transmission.

That's why i was asking! Better hope Southbend can work around it.

It may be a sidesaddle for European and medium duty applications (the info said Freightliner used this transmission in the FL mediums with the 900 engine). It may be a topside for the Ram application.

Might be time to get that dually I've always wanted. I would like to test drive it with the new transmission to see how smooth it is.



It's amazing they can reduce the clutch a half inch yet increase surface area by 33%. That should be able to grab the stump and lenghten the cab to a true quad cab.

Screw It

My next trucks gonna be a 6spd AUTO anyway... Oo. :-laf

hoping for that aisin 6 speed??? or is the next truck going to be a little bigger??? :-laf

The 12. 5" clutch has more contact surface area than the 13"...



It will be interesting to see how DC accomplishes that.



Also, 1st. gear is significantly lower than the NV5600. At idle clutch release should not be a problem, even loaded! Talk about a granny-gear!

Easy to get more surface area out of a smaller disc. The inner diameter was smaller thus adding to the surface area (inside hole smaller than the 13 inch unit). Less mass to slow down or speed up should help the shifting speed.

Page 14 is some good reading (like a higher OD, thats goofy)

That might be one good thing. I am always looking for 7th gear now. It would be nice to have two overdrives - one tall one for just running empty and saving fuel.

actually, the OD is not a higher gear, but a lower gear, but higher numerically. Not sure I like this. Wouldn't a . 50 to 1 6th make more sense than a . 79 to 1?

ahh, yes, I should have been more specific, numericly higher OD. . netting a higher RPM at given speed VS the NV5600 --- why would they do that and maybe effect mileage even worse?

 

[SRadke]

The new engines are being designed to operate at higher and higher rpm's for power and efficiency reasons so it makes sense they would use a trans to accomodate. Personally, I'l take my high OD.

the flywheel is a very bad idea!! ford-chevy both bad problems. hi bucks to repair. what are they thinking???

 

[Shooter]

Fords Dual disk clutch in my very very late 97 power stroke is why I bought a 00 Ram.



Higher numeric OD:: I guess you guys don't gross 20k and live where the speed limit is 75 and grades 8 - 10 %

Mbe G56 .... ?

See this link, page 2. http://www2.mercedes-benz.co.uk/con...ngle-MEDIA.tmp/Atego 815, 818, 823 CV 506.pdf.



G56 MB trans with the ratios everyone is talking about. I can't believe they are going to 0. 79 overdrive - waaay too low geared for my likes. I still want the 3. 54's back from my '01. Now - I wonder if the 6th gears from the G85 (with . 73 ratio) will fit in the G56 ... ?
