MANUAL TRANSMISSION
Designed as a replacement for the 5-speed NV4500, the NV5600 transmission is a 6-speed manual gearbox that was produced by the New Venture Gear transmission collaboration, between General Motors and Chrysler. It was used in Dodge trucks in 1999, 2000, 2001, 2002, 2003, 2004 and featured a much better gear spread and torque capacity than it’s predecessor. However, there were a number of NV5600 transmission problems that necessitated a redesign in 2001 of the clutch, shaft and synchronizer assemblies. While the Dodge NV5600 transmission offers an optimal gear ratio spread and improved fuel economy over the 5-speed NV4500, it may not be as reliable. Many owners have had to install a remanufactured NV5600 transmission due to a number of common failures, which include the rear bearing seizing and cracking the transmission case.
In 2005, 2006, and 2007, Dodge switched to the Mercedes-Benz G56 6-speed manual transmission that was designed specifically for light and medium duty diesel trucks. Compared to the NV5600 transmission that it replaces, the Ram G56 transmission is considerably lighter, and shifts smoother thanks to a dual mass flywheel. It can also handle considerably more torque, however the maximum torque capacity depends upon the model year and configuration. Trucks fitted with the 6.7L Cummins diesel engine and G56 transmission, will produce less torque than the automatic transmission version. The G56 transmission is a lightweight transmission that can handle moderately severe use. However, if the engine output has been increased above the stock level, the G56 has been known to fail prematurely due to the increased torque flexing the aluminum case and causing gear bind. There have also been concerns about the type of fluid to use in this gearbox, so take that into consideration when buying a stock one.
Looking for a manual transmission for your 2003-2007 5.9L Cummins? Look no further than the G56 transmission. With its durable construction and smooth shifting, the G56 is the perfect choice for your Ram 2500. Compare it to the NV5600 and see why the G56 is a popular option. Whether you’re searching for a replacement or an upgrade, CPP Diesel has you covered with the high-quality G56 transmission you need.
