G56 Bamboozal?

[QWaller]

I may be a little skeptical at heart, but I am starting to smell a rat. Makes me wonder if DC had an elaborate plan all along like Tommeygun suggested early on. Unload all the old NV5600s nationwide and clear the shelves of surplus autos at the same time. . Looks like it worked. Nothing but autos on our local lots last week. No changes in my mind, though. I like my workhorse and the little better ratios of the 5600 for my lifestyle.

That's a bit too Machiavellian for DC I would think. No doubt somebody has the same "fat finger" disease I have when typing and made a typo on transmission fluid amounts.

It seems totally ludicrous and unbelievable that lack of a mere quart of transmission lube would stall so many trucks - AND that it would take so long for DC to figure it out! And AFTER figuring it out, a simple memo to all dealerships instructing them to add that missng quart is all that would be needed - NOT leaving hundreds of trucks in freight yards and on rail cars, while waiting owners stewed...



I far more suspect something more serious was identified, and that added quart is a stop-gap "fix" until something more permanent can be developed and implemented...



Stay tuned for a quiet TSB/recall...



Shucks, *LOTS* of 2nd generation trucks were delivered with low lube levels - and DC sure wasn't concerned THEN!

Stay tuned for "as the gears turn".

Simple explanation to all these delays is quart of transmission lube, I don't think so.



This smells more like a cat covering up ... . Well you know what I mean. :-laf

You know what guys, sometimes it is just something simple and maybe something happened and had them looking in another direction until someone decided to check this one item and low and behold that was the problem.



Maybe the machine they use to fill the transmissions was just calibrated wrong and it was not caught right away.



Me thinks some of you are running a little wild with this.

WELL, John, you COULD be right - after some of the horror stories we've been exposed to at the hands of "5 Star" dealerships, I guess it really SHOULDN'T surprise us that it takes a week-long delivery stoppage for the DC "experts" to find out they're a quart low...



The trucks, that is...



Well, maybe them too...

 

[Gypsyman]

Maybe being one quart low allowed the output bearings to starve.

 

[john3976]

They could have pulled one off the line that was shipping and it was to noisy and they could not figure out why at first, who knows, but if it was all dealer I would say you guys are 100% right! go after them, but really I don't blame DC for keeping control of the parts as most dealers will just start replacing things until the problem goes away.



Real Mechanics are real hard to find these days.

I still stand by my original post on this. Assume it was the output bearing (probably assembled dry) and DC execs always looking to save warranty and screw the public, ignore the first few early failures. They let the trucks go and the dealer assumes all is well and delivers it to you. You load up the wife and kids for the first ride and hit the freeway at 70-85 to check for the vibration. The bearing locks up and you go skidding sideways into the oncoming lanes. Your wife and three year old are killed on the passenger side when you slide into the semi, your six year old soccer star is paralyzed from the waist down and you are in intensive care for two weeks.

Wake up and send DC a thank you for erring on the side of the customers safety this time.

"Assume it was the output bearing (probably assembled dry)"



OH, C'mon now - you don't REALLY think makers could do something as stupid as failing to properly lube vehicle parts do you?



OH, wait, they DID do that with U-joints and ball joints didn't they...



Disregard my post... :-laf :-laf

Makes a LOT of sense!!!

Just looked at the 05 service manual on G-56 overhaul. The mainshaft and countershaft bearings are heated to 212-350 degrees to install. If you heated them to the high end, any lube that was in the bearing from manufacturing would most likely melt out, leaving the bearing with minimal lube until splash lube got to it. I do not have a G-56 to look at, but I bet the fill level is below the output bearing level. That might explain why they are overfilling them, so the bearing gets lubed before running it at road speed for a while.
