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.
