History of the G-56 Controversy?

[Buffalo]

Today, I received a call from a Duramax friend of mine, who monitors this site, asking me what the story was behind all the controversy regarding the G-56. I, honestly, don't know the whole story. Could someone please tell us why this is such a hot topic.

What I do know is that it has a DMF, alum. case, different shift pattern for reverse, supposed to not support quite as much torque as the NV5600.
The rumor I heard was that the original trannies had the gear oil fill hole placed too low, therefore, not providing enough gear lube in the trans. I, also, heard that they started using another plug that was higher on the trans. case, therefore, raising the fluid level.

Another rumor was that DC stopped selling G-56 equipped trucks, at least, for awhile. My friend suggests that they stopped building the G-56's. I'm not sure about this, because, I had the opportunity to drive one a couple of weeks ago. My friend, also, said that He thought you couldn't order a new Dodge/Cummins with a G-56 until the '06's come out. Any truth to this? Is DC building new trans. cases with the fill hole placed correctly?

Anyone know of other uses for this trans. & how long it has been around? Basically, it's history?

I know this a very HOT topic on other threads. In no way do I want to throw Diesel Fuel on the fire. My friend and I would, sincerely, like to know what the history & story behind this transmission is, so that we may better understand why there are such heated discussions on this subject.

Thanks for your help.
