Leaks can be caused by overfills as well as by seal issues. Whether this was due to Daimler desires or functional considerations is unknown. Finer pitch placed more teeth in mesh at the same time, distributing the loads to reduce noise.įor 1997 Dakotas, a high-efficiency clutch hydraulic system provided smoother pedal operation, using higher internal pressure for greater precision, reduced hysteresis (the difference in operating force between release and engagement), and started engagement closer to the floor.įor the 2005 model year, Chrysler stopped using the New Venture Gear 3500, moving to the Getrag 238 six-speed gearbox (3.7/4.7 engines). Quieter operation resulted from a change to finer pitch gears for third and fifth speeds.
#NV3500 TRANSMISSION DRIVER#
A special synchronizer, different from the others, was designed to clash if the driver tried to get into reverse at a speed over 5 mph - perhaps by forgetting that it was a five-speed and not a six-speed. The shift pattern was a conventional "double H" setup with Reverse at the position where sixth gear would be, if there was a sixth gear - right and down, but and slightly further to the right than fifth. The force reduction resulted from addition of a second friction load path. To make engagement of the first and second gears easier, the 1-2 synchronizer had a dual-cone design that reduced shift effort by up to 40%.

Jeep used it later with its legendary 4.0 liter I-6 engine.įor 1997, refinements in the NV3500 manual transmission improved shift quality and reduced gear noise. For two-wheel drive, it had a long output shaft and rear case the four-wheel-drive version had a short output shaft and rear case. In the 1994 Dodge Ram and Dakota, NV3500 was paired with 3.9-liter V6 and 5.2-liter V8 engines and was available in two- and four-wheel-drive versions.
Its internal components were also lighter, resulting in easier shifts and a total 100 lb weight savings. The fully synchronized NV3500 manual transmission was first available to Dodge buyers in the 1994 Dodge Rams and Dakotas, as a replacement for the NV4500 it had an two-piece, aluminum-casting, split-case design that weighed less and had less noise than cast iron. Jeep bolted the bellhousing to the transmission case Dodge did not. The NV3500 can be identified by its two-piece aluminum case with an integrated bellhousing and top-mounted tower shifter. The New Venture Gear 3500, a medium duty five-speed overdrive manual transmission manufactured by New Venture Gear, was used in General Motors and Dodge compact and full-size light trucks.
