The Jatco 3N71 transmission was the first 3-speed automatic transmission from Nissan.
It was 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).
