List of Jatco transmissions

Last updated

Nissan and its spinoff, Jatco, have produced a large number of automatic transmissions for many auto makers.

Naming

The first Nissan/Jatco transmission, the Jatco 3N71 transmission, used a simple naming scheme: the "3" meant "3-speed", and the remainder was the series number. Beginning in 1982, it gained a locking torque converter (L3N71b) for greater efficiency. (See L3N71 link below). It gained an overdrive section in 1983 (L4N71b), culminating with preliminary electronic sensors and control functions being added in 1985 (E4N71b), and proceeding with the initial "R" for "rear wheel drive" with the RL4R01A/RE4R01A. This same system was used with the RL3F01A front wheel drive transaxle and its descendants through the RE4F04A.

Jatco has switched to a new naming scheme starting with a "J" for Jatco, then "F" or "R" for front- or rear-wheel drive. The next digit is the number of gears, while the model series is now two digits sequentially. The model series names were not directly mapped for instance the model designation changed when the RE4F04A was renamed to JF403E, while the RE4R03A became the JR403E.

Many OEM users assign their own model numbers.

A four-wheel drive, also called 4×4 or 4WD, is a two-axled vehicle drivetrain capable of providing torque to all of its wheels simultaneously. It may be full-time or on-demand, and is typically linked via a transfer case providing an additional output drive shaft and, in many instances, additional gear ranges.

<span class="mw-page-title-main">Continuously variable transmission</span> Automotive transmission technology

A continuously variable transmission (CVT) is an automated transmission that can change through a continuous range of gear ratios. This contrasts with other transmissions that provide a limited number of gear ratios in fixed steps. The flexibility of a CVT with suitable control may allow the engine to operate at a constant angular velocity while the vehicle moves at varying speeds.

The Nissan Sentra is a series of automobiles manufactured by the Japanese automaker Nissan since 1982. Since 1999, the Sentra has been categorized as a compact car, while previously it occupied the subcompact class. Until 2006, Sentra was a rebadged export version of the Japanese Nissan Sunny, but since the 2013 model year, Sentra is a rebadged export version of the Sylphy. The Sentra nameplate is not used in Japan. Many other countries in Latin America sell their versions of the Sunny as the Sentra. In Mexico, the first three generations of the Sentra were known as the Nissan Tsuru, and the B13 model was sold under that name until 2017, alongside the updated models badged as Sentra.

Hybrid Synergy Drive (HSD), also known as Toyota Hybrid System II, is the brand name of Toyota Motor Corporation for the hybrid car drive train technology used in vehicles with the Toyota and Lexus marques. First introduced on the Prius, the technology is an option on several other Toyota and Lexus vehicles and has been adapted for the electric drive system of the hydrogen-powered Mirai, and for a plug-in hybrid version of the Prius. Previously, Toyota also licensed its HSD technology to Nissan for use in its Nissan Altima Hybrid. Its parts supplier Aisin offers similar hybrid transmissions to other car companies.
