Dodge
introduced the NV5600 6 speed in 1998. The early version, which
is found in 1998 to 2000½ models is known to have synchronizer
problems and a weak input shaft. Midway during the 2000 model
year, a much improved NV5600 was introduced with a heavier 1⅜"
input shaft and reliable synchronizers. At the same time, the
old 12.4" clutch was dropped in favor of a 13" unit.
The NV5600, which weighs in at 465 lbs. is rated to handle
nearly 20% more torque then the NV4500HD five speed. First gear
and high gear are essentially the same ratios for both the
NV4500 & 5600. Reverse gear is lower in the 5600 then most
4500's. The direct gear (1:1 ratio) for the 5600 is 5th, in the
4500 it's 4th. From a drivability standpoint, the difference
between the two transmissions is the close ratio spacing of the
5600 doing in five gears what the 4500 does in four. Close shift
ratios is a great asset for hauling and towing but a bit of a
liability for daily city driving. The 6th or overdrive gear is
mounted on the front of the mainshaft instead of the back like
the NV4500. Consequently, the NV5600 does not have the problem
of the mainshaft nut backing off.
Upgrading Your Dodge To The NV5600 6 Speed
Installing a NV5600 6 speed in place of a NV4500HD in 1994 and
newer trucks is a straight forward job. The conversion usually
requires buying a new clutch with a 1.375" hub to match the
input shaft of current production NV5600s, but it is possible
(although not recommended) to get an early production
transmission with a 1.250" input shaft. |

Love
your 5 speed turbo-diesel Dodge but need another gear? No
problem with one of our popular bolt-in NV5600 retrofit kits for
1994-2002 Dodge trucks!
Complete kit includes
brand new NV5600 6 speed transmission, transmission filter,
shift lever, transmission oil, backup light wire harness, South
Bend MU13-1.375 ConO 13" clutch rated for 350hp, exchange
flywheel with ball pilot bearing, clutch release bearing
assembly, adjustable transfer case shift rod, transmission mount
plate, transmission mount, hardware, required chemicals video,
and install tips. 1994-1997 kits also include a new crossmember
and transfer case shift lever bracket. 1 year materials and
workmanship warranty.
Other 13" clutches rated up to 550hp are available! We do
not offer a 12.4" clutch option for the NV5600 even
though it would substantially reduce the price. Experience has
proven the 12.4" clutch with a 1.375" center hub is prone to
premature failure!!!
For 1989-1993 models, it is tougher (and more expensive) due to
the integral bellhousing design of the NV5600. A new flywheel
housing (the factory adapter between the engine and bellhousing),
cross member fabrication, floor modifications, clutch release
components, starter, exhaust rerouting, and driveline
modifications will be required. These extra parts (and labor)
added to the expense of the transmission itself, make
retrofitting the NV5600 into first generation trucks a challenge
to the average truck owner. Yet it can and has been done. |

installed on a NV4500HD that was run low on oil. This
transmission was rebuildable largely because of the
effectiveness of the QK1000! |
