Nv3500 transmission manual#
The distance between the centerline of the main shaft and the countershaft is 85 mmĬommonly known as NV4500, the New Venture Gear 4500 is a 5-speed manual transmission.Fully synchronized forward and reverse gears.Two-piece aluminum housing with no access plates.Between the extension and the shift lever, a rubber isolator kept vibrating. The shift lever extension of Dakota was round with a threaded bore screwed on the shift lever. The shift lever extension of the Dodge Ram had a square bore snapping over the transmission shift lever while pressing. Besides, the vented clutch housing decreased heat and elevated clutch life. The use of a front case, aluminum-casting clutch housing reduced more weight. The clutch assembly consists of a mechanical clutch system and hydraulic actuation system. All the gears constantly mesh with each other in these transmissions, but none transmitted torque until the engagement of the synchronizer. The NV3500 avails three synchronizer assemblies from the output shaft assembly: 1-2, 3-4, and 5-reverse.Ĭonstant-mesh transmissions used three different selectable snap rings that end-play clearances and adjusted gear. Besides, the shift forks controlled the shift of two different gears. This uses a nine-degree cone angle and can clash if there’s an attempt of a shift to reverse about 5 m/h.Ī single rail in the NV3500 controlled the three shift-fork assemblies. A slight offset between two shift gates and a reverse synchronizer prevented the shift from reversing during the forward movement. The use of helical-type, constant-mesh gears reduced the noise. NV3500 Engineering And Transmission Features In essence, the NV3500 is a five-speed manual transmission. Today, you may find the current NV3500 in full-size Dodge Dakota V8 Ram trucks from 1994 or later, S10 trucks from 1990 or later, and GM trucks from 1988 or later. The NV3500 complimented both two-wheel drive and four-wheel drive vehicles. Eventually, NV3500 re-designated as the 5LM60 with two different designs. In 1998, the NV3500 transmission was launched by the name of HM290. Dodge and GM used it in compact and full-size light trucks. New Venture Gear manufactured this transmission.
