The 63a transmission is a large strong transmission, and was made in a version to fit the A14 engine. It was adapted by Nissan to fill a marketing need in USA for a 5-speed (to compete with the Corolla SR-5) and so the existing 63A for the L-series L14 was modified to fit the small A-series A14 engine. This has two special significances:
- It is strong, suitable for overbored, supercharged or turbocharged A-series engines
- Its successor, the 60-Series Transmission 5-speed is much lighter and so a better fit for A14 and A15 naturally aspirated engines. The 60 is also smaller than 63 and so a better fit in Datsun 1200s.

Overview
For an overview of 5-speeds in general, see:
5-Speeds Comparisons, Ratio info, etc.
Datsun gearboxes are numbered by the distance between the centres of the countershaft and the main shaft. The 63-series has 63 mm between the shaft centres, so can fit larger, stronger gears than the smaller 60-series and 56-series boxes.

This is the FS5W63A "dogleg" trans. Note the casting line around the center section on the otherwise smooth housing.
Debut dates for The 63A 5-speed variants:
- 1973 for L14 PB210 JDM
- 02 1976 for L14 B211 JDM
- 02 1976 for A14 B211 JDM
- 04 1976 for A14 B210 USA
The 63 transmission came with A14-powered B210 (HB210 and HLB210). It was not used by Nissan Competition for racing. Instead the 56-series was recommended for the small cars, and the 71 for the larger cars.
The 1976.5-1978 USA got B210 Coupes with factory 5-speed transmissions. Here's an advertisement for one:

Dogleg Shifter
Like most A-series 5-Speeds, the 63A is uses a "dogleg" shift-pattern (aka 'reverse shift').

The 63-series 5-speed for Nissan A Engine came in 1976-1/2 to 1978 Datsun B210 with A14 engine. USA and Japan markets had such cars.

Identification
See main article: 5-Speeds
The "A" indicates the transmission revision, not the engine type it fits.
? my casting has a 63A#1 cast were there different versions?
63A #1 63A #2 63A #3
63 series L-engine vs A-engine
The 63A came in two versions:
- 63A to fit L-series engine
- 63A to fit A-series engine
So check the bellhousing bolt pattern.
63 series gearboxes speeds were available for A14 engines and for L-series engines, Z-series engines and J-series engine. So be careful to match the bell pattern and make sure the one you buy fits the A-series.
A-series has starter at about 8:00 O'Clock position
L-series has starter at about 9:00 O'Clock position
A-series bell pattern from rear of engine
4-speed vs 5-speed
Old 63-series 4-speeds have a bottom pan - like an automatic transmission - and are used with L-series, Z-series, and J-series engines.
- Was used in JDM PB210 with L14 as standard fitment (5-speed optional)
4-speed F4W63L
4-speeds come with bottom pan (old style) or without bottom pan (new style). If you see the bottom pan, it's a 4-speed
NEWER 4-speed are 71B series and look very much like the 5-speed.
L-series application included: * 1975-1979 620 USA * 1980 720 USA Z-series application included * 1980-1981 A10 USA Z20S engine * 1978-1981 A11 JAPAN Z18/Z16 engine
Clutch
63-series take the L-series type input shaft, but small-diameter (standard diameter) A-series size clutch disk. The 63A was first available in USA in April 1976, and only in Coupe.

Driveshaft
You'll need a Propeller Shaft from an AT equipped car as it uses the same output shaft. The 63A is the same length as the B110/B210 automatic. It is a different length than the B310 automatic.
- B110 Auto shaft: 1349 mm (53-1/8")
- B210 Auto shaft: 1345 mm (end-to-end)
Automatic Car
It's easy to get the 63 in if your 1200 was originally an automatic - it will have the wider transmission tunnel. Use the automatic Gearbox Mount and make an adapter plate that will move the mounts to the right spot. Some say you can simply reverse the auto mount as-is.
Manual Car
For manual 1200 car, remove the factory mounting bosses from the tunnel, and fabricate new ones:
Note that the factory crossmember mounting brackets have been removed from inside the tunnel. This custom crossmember bolts to the floor.
Tunnel Mounts Removal
Discussion: Tunnel mount removal?
The rear engine mount (gearbox mount) brackets are spot-welded on. Don't drill them right out. There is a special spot weld removal drill bit. Go to Mitre 10 or a decent Hardware they will have them. Grab a wire wheel or coarse sand paper sand around the mounts so you expose the spot welds a bit better and then carefully drill with the bit it will leave little lumps and you can file or coarse sand them down smooth. The last thing i would want is more holes in the body and floor -- they are thin enough already.
The only problem is that the spot weld drill bit insanely high-priced.
Speedometer Cable
For RHD 1200s with the short cable, use a Datsun 810 speedometer cable, it's about 150 mm longer.
