The 71 transmission is Nissan's strongest transmission. It was fitted to L-series six cylinders, FJ engines and more. 71 series comes in four different lengths, however a stumpy version is the same length as a Datsun 1200 transmission though obviously much larger around. The stronger 71B replaced the original 71A designs in the 1970s.

Overview
The 71-series has the mainshaft and countershaft 71 mm apart. This larger transmission is thus stronger than the 56-series used in the Datsun 1200, and stronger than the 63-series used in some A14-powered B210s. The C revision boxes (FS5W71C) was used with 3-liter V6 engines.
While never offered in an A-series version (it would be overkill even for a supercharged A-engine), the 71 is a good choice for larger engine swaps.
71 series is also the size of the Datsun 1200 Automatic Transmission, so an automatic Tunnel will fit them.
Lengths
Long extension housing is the most common.

Interchange
Like transmission parts interchange:
- 71A bell housings
- 4-speed to 4-speed
- 5-speed to 5-speed
- 71B/71C front cases
Complete transmission units of the same length interchange. For example, replacing a shorty FS5W71B with a shorty FW471.
