L-series and Z-series/KA-series use the same bell patttern -- BUT the L-series is a slant engine. So while the transmissions will physically bolt on, use the Z-/KA front case with the Z-series engines, and the L-series front case with the L-series engines. OR, you can bend the gearshift to the appropriate angle, but you risk transmission oil leaking out. | L-series and Z-series/KA-series use the same bell patttern -- BUT the L-series is a slant engine.

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.
Contents |
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.
Although the Nissan 90-Series Transmission was rated higher, experience shows that the 71C is practically just a as durable even behind a 300ZX turbo (see Gearbox Strength).
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 (L3N71B), so a 1200 automatic Tunnel should fit them.
Transmission Parts Codes:
- 32010 TRANSMISSION ASSEMBLY
Lengths
Long extension housing is the most common.
Overall Transmission Assy Length Long tail #1: 31.5 inches Long tail #2: ? inches Tail #3: ? inches Short tail: 26.3 inches (stumpy)
Stumpy
- 71-Series Transmission
- Skyline DR30 (FJ20 engine with 71C)
- Datsun 720 pickup USA (71B)
71 Original
F4W71
Short 4-speed with flanged output
- 1969-1972 Datsun 521 with L16 engine

- Datsun 240Z early USA dealer installed with L-series bell
71B
Look for 71B cast into the transmission case.
F4W71B
Short housing
- Datsun 720 with Z-series engine (short 26.3")
(1972-1982) long housing. Rear extension of transmission has bolt-on cover plate.
- 1972-1973 Datsun 240Z

FS5W71B
Long extension housing
- Datsun 200SX (S110) with Z20 engine
- Datsun Maxima (810) with LD28 diesel
- Nissan 720 with SD diesel
- Nissan 200SX with CA18ET engine

Engines L-series (various) Z-series (S110) LD28 diesel (Maxima) SD diesel (Nissan 720) CA18ET (Nissan 200SX)
71C
FS5W71C - The 71C has a different shifter than the 71B and all versions are longer than the 71B. A 71B front housing can be swapped.
- 1983- Nissan 300ZX (non-turbo, turbo uses 90-series)
- 1986-1989 Nissan D21 (Hardbody) with Z-series engine
- 1989- Nissan D21 (Hardbody) with KA-series engine
- Pathfinder/Xterra/Frontier with KA-series engines
- Pathfinder/Xterra/Frontier with VG-series (V6) engines
Engines VG-series (V6) KA-series Z-series
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.
L-series and Z-series/KA-series use the same bell patttern -- BUT the L-series is a slant engine. So while the transmissions will physically bolt on, use the Z-/KA front case with the Z-series engines, and the L-series front case with the L-series engines. OR, you can bend the gearshift to the appropriate angle, but you risk transmission oil leaking out.
