Anyways, the Getrag was known for its unreliability. Thats just the way it is. NV4500 is more reliable but it does have that 5th gear nut issue which is not hard to fix.
The NV5600 is rated for more power than the NV4500 but parts are much more expensive and plenty of problems were reported even at stock power levels.
Now they run the G56 and its the "cat's meow".
Aisin automatics are rated for far more power than even the G56, 850ft-lbs vs 660 ft-lbs and some years were 600ft-lbs.
They say the new Aisin can handle up to 950ft-lbs. The 68RFE could handle more than the manual as well.
There are plenty of people out there who have had no issues with any of the stick shifts. The most common misconception is that the manual transmissions are more reliable than automatics. Mild upgrading with a good torque converter makes an automatic way more durable than the manual.
If you interested in any kind of upgrades to your 1st gen with a Getrag, you should consider just dropping in the NV4500. Very common, relatively cheap and will hold more power than what its rated for so long as you dont drive like an idiot.
what are you basing all of that information and recommending on ? everything i have seen and heard is just the oposite that 'cats meow' was more like a mashed cat losing its guts have not heard of near the problems with new venture trannys like I have with the get-rags what about that dual disk clutch tht slips with a heavy load and a head wind? it is another daimler great idea
What I have heard is what I have heard.
I currently have a NV4500 5 speed in. I chose this trans because of its overall reliability and cost effectiveness for what I do.
G56 tranny's are very reliable under reasonable power.
The NV5600's did have problems even at stock power levels but I do believe that a hole drilled provides lubricant to solve that.
You hear what you hear, and I do as well.
Oh and if you are interested, Dieselhub.com has excellent transmission writeups under the transtech tab.
EDIT: If you are confusing the Getrag (G360) with the G56, they are two completely different transmissions.

Today's Featured Article - Restoration Story: 1964 JD 2010 Dsl - Part 2 - by Jim Nielsen. Despite having to disassemble the majority of my John Deere 2010's diesel engine, I was still hopeful I could leave the engine-complete with crankshaft and camshaft-in the tractor. This would make the whole engine rebuild job much easier-and much less expensive! I soon found however, that the #4 conrod bearing had disintegrated, taking with it chunks of the crankshaft journal. As a resul
