Castrol Syntorq synthetic 75W GL-4 or equivalent specification details in next section below Lubricants that meet the Syntorq spec include:. Amsoil synthetic 75W GL-4 manual transmission fluid. The NV features carbon fiber composite synchronizers and is therefore highly sensitive to transmission fluid type and viscosity. The fluid has become difficult, if not impossible to source no longer produced by Castrol? However, Chrysler and GM continue to offer their formulations, part numbers replaces and replaces respectively. Amsoil 75W manual transmission fluid is a popular alternative that also meets the NV's fluid specifications at a much lower cost. The OEM fluid is relatively expensive, however frequent transmission service is unnecessary and total long-term service costs are therefore relatively small. This also does not infer that a GL-5 oil that meets GL-4 spec is compatible. Certain formulations may provide greater lubrication characteristics and reduce gearset wear, but at the expense at more rapid synchronizer erosion. A synchronizer requires a degree of friction in order to increase or decrease the angular velocity of a gearset and allow for smooth gear progressions. In addition, the NV's carbon fiber synchronizers may deteriorate if an incorrect fluid is used. NV owners are therefore ill advised to stray from the factory intended fluid spec and should err on the side of caution by selecting an OEM transmission fluid or confirmed suitable alternative.

The synchronized reverse was also added and the front nv4500 overdrive ratio retainer was enlarged from 5. All Gears Main Case If oversize tires are being used, some Jeeps may never see overdrive and lower axle gearing may be in order to compensate for the NV's taller low gear.

California Proposition The NV 5 speed manual transmission is primarily a New Process Gear design that was assembled at the Muncie Transmission plant from late to mid The quality of genuine New Venture Gear components is excellent, and we still continue to stock any genuine NVG parts we can find, but today, most of the NV parts we stock will be high-quality replacement parts manufactured overseas. The NV transmission was initially designed to allow for close, medium, and wide ratio models, plus there were plans for a NV 6 speed with a double overdrive. Only the wide and medium ratio 5-speed versions saw production.

The NV or New Venture Gear is a heavy-duty, manual shift, five-speed overdrive, longitudinally positioned transmission. It was introduced into Dodge trucks in Though it has it roots as the New Process four-speed beginning as early as in Dodge trucks, its current incarnation as we know it today is quite different. The NV is a top loading five-speed transmission with a cast iron case, aluminum top cover and dual PTO ports. It features all helical gears, and is fully synchronized. The NV has a case length of GM 4wd versions featured an extension housing length of 6. There are various other Dodge and GM 4wd and 2wd housings. This housing contains fifth gear and as usual, 2wd style housings are longer. A unique feature of the NV is its fly-weighted 1st-to-2nd gear synchro assembly, preventing a downshift at excessive revs.

The NV transmission identification tag is attached to the shifter top cover. The tag provides the transmission model number, build date, and part number. Be sure not to remove the I. The information on this tag is essential for ordering the correct replacement parts. It was also the first year that Chevy changed the bellhousing-to-transmission bolt pattern. This transmission is ideal when converting your vehicle, providing an ultra-low 1st gear. GM, however, only produced this particular ratio during these years. The major complaint of this 5 speed was stiff shifting and noise in 3rd gear.

For most conversion applications, we like the Dodge gas version transmission with a GM input shaft. The transmissions are also equipped with synchronizer rings that are made of a fibrous material.

The NV transmission is a heavy duty 5-speed that saw use in a number of Chrysler and GM trucks from —

Last edited: Apr 19, This feature was dropped for according to our GM parts book, however we have found them on some transmissions. A synchronizer requires a degree of friction in order to increase or decrease the angular velocity of a gearset and allow for smooth gear progressions. Due to the interchangeability of other NV components, we recommend that you also verify the following information: Starting at the front, this Dodge transmission should have an input shaft pilot tip diameter of. These tailhousings did not use a standard mechanical speedometer drive, but were equipped with an electronic speedometer setup. The transmission has the lower 6. You are using an out of date browser.
