That, combined with a low ceiling, makes it difficult for just four speakers (two in the front of the room and two in the back) to image a sound above my head convincingly. My own home theater is a long room with a lot of space behind my seats. This was changed to 29 splines after the 2001 model year.Nonetheless, for some of us, a limit of four height channels isn’t enough to fill the top of the room with sound. The Dodge NV4500 2wd transmission had a 30 spline output shaft, and the Dodge NV4500 4×4 transmission got a 23 spline output shaft. 1993+ Dodge NV4500 had a 10 spline input shaft that measured 1.25 inches in diameter. The 1992 Dodge NV4500 had a 19 spline 1 ” diameter input shaft. Other differences between the Dodge NV4500 and the GM NV4500 include a concentric internal hydraulic slave cylinder with an integrated and throwout bearing. This version of the NV4500 transmission also had an integrated interlock mechanism to prevent 2>1 downshifts when the speeds were too high. It also used carbon fiber composite synchronizer rings, with dual cone synchronizers for 1st and 2nd gears. For example, the 1992 – 1997 Dodge NV4500 transmission used a higher gear ratio than it ’ s General Motors counterpart. This common Chevy 5 speed manual transmission 4×4 also came with an 8 1/8 ” tail housing and a 32 spline output shaft.Īlthough the Chevy NV4500 and Dodge NV4500 are nearly identical twins, there are some fundamental differences that made them unique to their respective automotive brand. The GM / Chevy NV4500 4WD transmission had a 1 1/8 ” x 6 5/8 ” 10 spline input shaft with a 0.590 ” pilot tip. They also gave it a synchronized reverse gear and increased the size of the front bearing retainer from 5.125 ” to 5.6 ” in diameter. The 1995 and later GM / Chevy NV4500 was updated to a 5.61 first gear and 6.043 ” front bolt pattern that was used in the Dodge NV4500. It also has a 4.685 ” front bolt pattern. In order to maximize engine torque when necessary, the GM / Chevy NV4500 transmission used a granny low 1st gear with a ratio of 6.34. This new joint venture was ironically named the New Venture Gear Corporation, and the NV4500 transmission was gearboxes to be made by the new cooperative. The design and production of the NV4500 came after a merger between the General Motors Muncie transmission division and the Chrysler transmission. Interestingly, the Dodge NV4500 / Chevy NV4500 was introduction for nearly 20 years (1992 – 2007). Since the NV4500 transmission was designed for use in heavy duty applications, it has a granny-low 1st gear, dual PTO ports, and a sturdy cast-iron case with an aluminum top cover. Reverse gear was not synchronized until later in the production line. It uses a constant mesh helical gear arrangement with fully synchronized forward gears. The result of a joint venture between Chrysler and General Motors, the NV4500 transmission is a heavy duty 5 speed manual transmission. And speaking of, shipping is always Free, and you also get a 3-Year/Unlimited Mile Nationwide Warranty that covers parts and labor for repairs that are performed by any licensed repair shop in the country. Once complete, your newly remanufactured NV4500 transmission is dyno tested to break-in all of the new parts, and to ensure that everything works correctly prior to shipment. They also create less friction for reduced operating temperatures and a longer transmission life.Įvery remanufactured Street Smart Transmission undergoes multiple inspections by Certified inspectors throughout the build process. This upgrade is especially important for severe service (towing, off-roading, performance driving), where heat buildup can be a serious concern.Īll of the new hardened bearings in a remanufactured NV4500 transmission not only perform better under load. To increase longevity, every remanufactured NV4500 transmission gets upgraded seals and gaskets that are made from a stronger heat resistant material. Any hard part that shows signs of wear or damage is immediately replaced. Now let ’ s take a closer look at what sets a Street Smart Transmission apart from the rest:Īll Gears & Shafts Meet OEM SpecificationsĪll of the gears and the main shaft inside each remanufactured NV4500 that we produce, is carefully inspected for cracks and tested for straightness. By the time it’s finished, a reman transmission should perform exactly like a new one. And every “ hard part ” that doesn’t measure up to the manufacturer’s original specifications, gets replaced. They test everything from metal thickness to spring tension before the process begins. Each remanufactured NV4500 is built in our state of the art factory by skilled Certified technicians. Put simply, a remanufactured transmission is a used transmission that has been returned to a like-new condition.
