Successor 4R01

The 4N71 was a 4-speed automatic transmission from Nissan Motors. It was available as either a light-duty ("L4N71B") or medium-duty ("E4N71B") unit for rear wheel drive vehicles with longitudinal engines. The latter used an electronically controlled lock up torque converter.

Automatic transmission type of motor vehicle transmission that can automatically change gear ratios as the vehicle moves

An automatic transmission, also called auto, self-shifting transmission, n-speed automatic, or AT, is a type of motor vehicle transmission that can automatically change gear ratios as the vehicle moves, freeing the driver from having to shift gears manually. Like other transmission systems on vehicles, it allows an internal combustion engine, best suited to run at a relatively high rotational speed, to provide a range of speed and torque outputs necessary for vehicular travel. The number of forward gear ratios is often expressed for manual transmissions as well.

Longitudinal engine internal combustion engine in which the crankshaft is oriented along the long axis of the vehicle, front to back

In automotive engineering, a longitudinal engine is an internal combustion engine in which the crankshaft is oriented along the long axis of the vehicle, front to back.

Nissan Maxima Car model

The Nissan Maxima is a mid-size car manufactured by Nissan and sold primarily in North America, the Middle East, and China. Making its sales debut in 1981 for the 1982 model year as the Datsun Maxima, it replaced the earlier Datsun 810. The name "Maxima" dates back to 1980 for the 1981 model year when the upscale 810 sold as the "810 Maxima" in North America. Like the 810, early versions of the Maxima had their origins in the Datsun/Nissan Bluebird. The Datsun brand was phased out in favor of Nissan in 1984 for the 1985 model year, thus becoming the Nissan Maxima.

Nissan 300ZX

The Nissan 300ZX is a sports car in the Nissan Z-car family that was produced across two similar but unique generations. As with all other versions of the Z, the 300ZX was sold within the Japanese domestic market under the name Fairlady Z.

The Nissan Skyline is an automobile nameplate originally produced by the Prince Motor Company starting in 1957, and then by Nissan after the two companies merged in 1967. After the merger, the Skyline and its larger counterpart, the Nissan Gloria, were sold in Japan at dealership sales channels called Nissan Prince Shop.

Holden Commodore (VL) car model

The Holden Commodore (VL) is a mid-size car that was produced by the Australian manufacturer Holden from 1986 to 1988. It was the final iteration of the first generation of the Holden Commodore and included the luxury variant, Holden Calais (VL). Between February 1986 and August 1988, 151,801 VL model Commodores were built.

Chrysler K platform automobile platform of compact-to-midsize cars

The K-car platform was a key automotive design platform introduced by Chrysler Corporation in 1981, featuring a transverse engine, front-wheel drive, independent front and semi-independent rear suspension configuration—a stark departure from the company's previous reliance on solid axle, rear-drive configurations. Derived from Chrysler's L-cars, the Plymouth Horizon and Dodge Omni, the platform was developed just as the company faltered in the market, at first underpinning a modest range of compact/mid-size sedans and wagons—and eventually underpinning nearly fifty different models, including all-wheel drive variants—and playing a vital role in the company's subsequent resurgence.

Nissan CA engine

The CA engine is a 1.6 to 2.0 L Inline-4 piston engine from Nissan designed for a variety of smaller Nissan vehicles to replace the Z engine and some smaller, four-cylinder L series engines. It is an iron block, aluminum head design with a timing belt, cheaper to make than the timing chain setup on the Z and L engines. Earlier versions featured SOHC and eight valves. The new CA block design was a scaled-up E series block with timing shaft and other ancillaries removed. The oil pump is fitted directly onto the crank nose and the distributor is driven by the end of the camshaft. Like the E series and the A block from which the E was derived, Nissan used a taller block for the largest stroked 2.0-litre engine. The CA was designed to be compact and light, with a CA16 requiring only 195 litres of space, while weighing 23% less at 115 kg (254 lb). The engine was called the "CA" series for Clean Air, due to the installation of Nissan emission reducing technology, called NAPS-X.

The Mitsubishi Astron or 4G5/4D5 engine, is a series of straight-four internal combustion engines first built by Mitsubishi Motors in 1972. Engine displacement ranged from 1.8 to 2.6 litres, making it one of the largest four-cylinder engines of its time. It became the first Japanese production engine to combine both electronic fuel injection (EFI) and turbocharging.

TorqueFlite

TorqueFlite is the trademarked name of Chrysler Corporation's automatic transmissions, starting with the three-speed unit introduced late in the 1956 model year as a successor to Chrysler's two-speed PowerFlite. In the 1990s, the TorqueFlite name was dropped in favor of alphanumeric designations, although the latest ZF-based transmissions with the 8-speed automatic has revived the name.

Nissan Z engine

The Nissan Z engine is a series of automobile and light truck engines that was engineered by Nissan Machinery, manufactured by the Nissan Motor Company from 1979 through August 1989. All Z engines had 4 cylinders, a total of 8 valves and a single overhead camshaft (SOHC). Displacements ranged from 1.6 L to 2.4 L.The Z series' engine blocks were nearly identical to those of the earlier L Series with the exception of the Z24. While the Z16 and Z18 engines had a deck height similar to the earlier L13/L14/L16/L18 variants, the Z24 had a taller deck height to accommodate a longer stroke. The most notable difference between the Z-series engine and its predecessor was the introduction of a new crossflow cylinder head which reduced emissions by moving the intake ports to the right side of the engine opposite the exhaust ports. This change allows the exhaust port velocity to more effectively scavenge the cylinder and reduce reversion pulses to enhance induction. The Z series evolved into the NA and KA engines which, along with the smaller CA series, replaced the Z series.

The Jatco 3N71 transmission was the first 3-speed automatic transmission from Nissan. It was an introduced as a conventional alternative to the then-ubiquitous and popular Borg-Warner Type 35. It was designed for use with rear wheel drive vehicles with longitudinal engines. In 1982, it gained a locking torque converter (L3N71b) for greater efficiency, and gained an overdrive section in 1983 (L4N71b), culminating with preliminary electronic sensors and control functions being added in 1985 (E4N71b).

The 4R01 was a 4-speed automatic transmission from Nissan's Jatco subsidiary. It was available as either a light-duty ("RL4R01A") or medium-duty ("RE4R01A") unit for rear wheel drive vehicles with longitudinal engines. Mazda called the medium-duty version their R4A-EL.
