Manual Transmission NV4500 Conversion Print E-mail

Our remanufactured Heavy Duty NV4500's are 5-speed constant mesh manual transmissions, all gear ranges including reverse nv45004wd_large.jpgare synchronized it's a top loader with a cast iron case and an aluminum shift cover also comes with an aluminum bell housing for conversion. Thes transmissions have updated main shafts, 5th gear and 5th gear nut.  Replacement unit do not include bell housing. Two versions of New Venture Gear Manufactured NV4500 are used in 1994 and later up to 2002 models of the Dodge 3/4 and one ton vehicles, a standard duty version is used for 5.2L and 5.9L applications and a heavy duty version is used for Cummins diesel engines. The main differences between the two versions concern the larger input and output shafts used in the heavy duty version, Chevrolet also used this transmission.

The NV4500 is a top loader style transmission. The shift lever is located in the shift cover bolted to the top of the shift cover and operates the shift forks and rails directly. The shift forks and rails are all located within the aluminum cover which is bolted to the top of the gear case. Dual cone synchronizers are used for first and second gears. The 1-2 synchronizer have a set of spring loaded flyweights in the syncro hub that govern shift speeds, to prevent over-revving on a 2-1 downshift. Our NV4500 transmission includes reverse gear inhibitor mechanism that prevents engagement when shifting into forward gear ranges. The inhibitor mechanism is located in the shift cover.

Additional features of our remanufactured NV4500's includes tapered roller bearings support the drive gear, main shaft, and countershaft in the gear case. Pilot roller bearings in the drive gear hub support the forward end of the main shaft. The main shaft gears are supported on caged type roller bearings. Drive gear thrust reaction is controlled by a needle type thrust bearing located at the forward end of the main shaft, those features make this NV4500 a great replacement for the earlier Getrag 360 used by Dodge. Reverse gear and forward gears 1-4 are mounted inside the main transmission case, 5th gear is mounted in the tail shaft assembly. Our remanufactured transmission all come with updated main shaft to prevent know problem of 5th gear backing off the shaft if the vehicle is lugged while towing.
