Well, I have a terminally garage-bound '68 Spitfire. But I have learned a lot from it. And that's why I bought it originally. I definitely learned a lot. One of my desires is a roadworthy TR6, and my budget definitely permits this. I would definitely go for a 5-speed conversion. Then again, how do I want to maximize my available capital? I saw a beautiful 912 for sale in LA selling for about as much as I'd have to put into a TR6 to make it as nice. I'm not bragging, but it's good to have the financial resources to make these choices. I will have a great car.

Toyota Motor Corporation's W family is a family of RWD/4WD transmissions built by Aisin.Physically, these transmissions have much in common (like the bell housing-to-body bolt pattern) with other Aisin-built transmissions, like the Jeep AX-5 and the Toyota G-series.The W55, W56, W57, W58, and W59 are externally and internally very similar aside from the gear ratios. 5 speed adapter kit (plate, cluster gear, instructions, etc. Does not include R380 gearbox) $ No longer available.The 5 speed set up does not allow for transfer case PTO units. To fit the complete unit into your SIIA/SIII you can either move the transfer case 4' back, or you can move the engine 4' ahead. The 902 is the same size and has the same internals as the 901, but different gear ratios. It is an appropriate gearbox to use for the 5 Speed Conversion outlined below. A late model 914 Side Shift transmission can be used for a 5 speed conversion but requires additional work and components not covered in the article below.

The only Datsun 1200 that came with a 5-speed was the Japan-market 1972 GX-5 model. However any A-series 5-speed will bolt to the A12 engine and work in a 1200 as-is or with some degree of modification.
The Datsun 1200 GX-5 model came with a non-overdrive five speed. B210 and B310s came with various 5-speeds that can be fitted to B110: All transmission.
- F5C56A (B110) non-overdrive a la B110 GX-5
- F5C56A (B210)
- FS5W63A overdrive, JDM HB211, JDM KHB310 Sunny Coupe, USA B210s
- FS5W60L (B310 - HB310) overdrive (1979)
- FS5W60A (GB310 - PB310) overdrive (1980-1982)
- RS5W60A (Vanette) is an external shifter model, but can be used for parts for the FS5W60A
5 Speed Gearbox For Bullet
Mac os emulator for pc. Adding an overdrive 5-speed is one of the best improvements that can be made to the Datsun 1200. More relaxed, quieter, more fuel-efficient highway cruising will result. This was Mareo's idea, and I think he might be right.
Then there is the performance 5-speed, which does NOT lower RPMs on the highway, does not improve fuel economy. This is the GX5 transmission, it provides an extra gear in-between 1st and Top. These gears allow you to shift more often, keeping the engine in the fattest part of the rev range for quicker acceleration. The only A-series gearbox that is non-overdrive like this is the 56A 5-speed.
On the other hand, if you don't do much highway driving consider that the A12 4-speed is lighter and cost less. It's also better suited to the stock A12 torque curve than any of the overdrive gearboxes. It has a relatively steep 1st gear for effortless take-offs even with 4 passengers, yet still allow a 90 mph top speed, while 80 mph cruising @ 5000 RPM is perfectly do-able if a bit noisy. Remember, the Yellow Line doesn't even start until 6000 RPM on a Datsun 1200.
Also, a 5-speed won't improve your top speed. Datsun 1200 top speed is about 95 mph and is HP limited (not gearing limited). Highest speed in the 1200 GX5 is achieved in 4th gear as it needs to run at 6000 RPM to make enough power.
- 56-Series Transmission (non-overdrive)
- small, light, with visible ribs along case similar to B110 4-speed
- Performance use. Does not lower RPMs or reduce noise at highway speeds
- Suitable for A12 engine. Not strong enough for A14
- The 5-speed versions were 1:1 direct fifth-gear (non-overdrive), called in Japan 'direct mission'
- Fitted to B110 GX-5 and early (A12T) B210 GX-5
- 60-Series Transmission
- smooth-case medium-size transmission suitable for A14 and A15, but works with A12 too
- These come in 60L (dogleg, 1979) and 60A (non-dogleg, 1980-1982) varieties
- Fitted to B310
- Vanettes have the 'R' version (remote shifter for column shift) so it is not a feasible choice. See 5-speed
- 63-Series Transmission
- Large, heavy transmission commonly used with L-series engines, a version was also fitted to A14 engines in B210s
- Overkill for the A-series engines, strong enough for supercharged A15
- The 5-speed version is a 'dogleg' shifter
- Fitted to JDM B210 with A14 engine 1976-1977
- Fitted to all North American B210 hatchbacks from 1976-1/2 through 1978 model years (starting in 1977 for Canada)
Any A-series rear-wheel-drive 5-speed will bolt up to any A-engine. Slight modifications may be needed to fit into Datsun 1200.
And, A14/A15 5-speeds will handle the extra torque of these motors (The A12 4-speed is a little weak to use with an A15).

In USA, the B310 5-speed is common and inexpensive. Just look for a 1979-1982 Datsun 210 (Nissan body type B310 aka Sunny). You can often buy a whole car for about $500 or less. In the wreckers, transmissions go for about $200 u-pull. The B210 5-speeds are less common, but go for the same price if you find one (prices last checked in 2010).
In Australia, ask around. They can be hard to find and expensive.
Be sure to get:
- The gearbox crossmember from the donor car (it may be useful)
- The rubber transmission mount insulator. There are various types, so get the one that matches the transmission
- Clutch release lever and release bearing sleeve (throwout bearing sleeve)
- Engine plate, if the 5-speed used one. The release bearing sleeve and plate are a matched set
- You may use your existing flywheel and clutch cover (pressure plate)
Additionally, the 63-series gearbox will require:
- Clutch disc for 63-series transmission. All other 5-speeds use the same clutch as stock Datsun 1200
- 1200 Automatic Propeller Shaft fits the 63-series gearbox. All other 5-speeds use the same driveshaft as the stock 1200 4-speed
Most of the 5-speeds use a 'dogleg' shift-pattern (aka 'reverse shift').
ONLY the 60A 5-speed is a non-dogleg. It was used starting with 2nd-year B310, from late 1979.

The 1984 Nissan Competition Parts catalog says:
The 5-speed transmission (F5W56A) was originally installed on certain non-USA models of the 1200 [JDM Datsun Sunny 1200 GX5]. With the stock gearing this transmission works very well for street, slaloms, high-speed time trials or rallies. With the optional gearing (32010-H7220N), it is the best production-based transmission available for racing versions of the 1200, B210 or 210 Datsuns. The synchro mechanism is the servo-type (steel).
The Part Number above [3210-H7220N] is a Nissan Competition number. They often put N or R after the regular number. Without or without the 'N' suffix, that number describes the 56A five speed 'Option 1' close ratio competition transmission for these models.
The F5C56A [JDM Option 1] is as rare as hen's teeth. These were racing parts, and thus are difficult to find and expensive. Some Japanese dealers fitted them to retail GX models for special customers. The Japan domestic model Datsun 1200 GX-5 came with the wide ratio F5W56A as standard. This was also available from Datsun Competition.
The Option 1 box came with the ratios of
1st 2.676
2nd 1.691
3rd 1.398
4th 1.181
5th 1.000
Rev 2.877
The Option 2 box was for Japan Domestic Racing.
The factory 1974 Datsun B110 Competition Tune Up Manual lists only the Option 1 & 2 four speeds which were superseded by the Option 1 five speed. The ratios are as listed above except for 4th gear which is shown in this book as 1.182.
The factory 1974 Datsun Sunny 1200 [K]B110 Sports Option parts Catalogue lists only the Option 1 five speed with the ratios matching those listed above exactly.There was no Option 2 five speed listed in the Japanese Datsun Sunny 1200 [B110] Factory competition literature.
I speculate that the US arm of DatsunSport quite possibly listed the stock F5W56A [wide ratio transmission] as their Option 1 gearbox & the real Option 1, the close ratio F5C56A competition transmission, as their Option 2 offering, thereby confusing the situation completely. [Author KB10]
B110 GX5 JDM came with
1st 3.757
2nd 2.374
3rd 1.659
4th 1.254
5th 1.000

Rev 4.040
The factory 'Datsun 1200 Sports Option Parts' Catalogue for the 'Model: B210, KB210 Series' lists an Option 1 five speed 56A transmission. It is identical in every way to the one listed in the 1200/ B110 factory competition literature. There is no Option 2 transmissions listed here either.The stock B210 Sunny GX5 used the F5W56A transmission.
The overdrive 5 speeds have:

3rd 1.378
4th 1.000
5th 0.875 or 0.825

5 Speed Gearbox Diagram
Gearboxes are rated for torque (twisting force). Peak Horsepower is not a factor. It doesn't matter how much horsepower you have; whether you need a stronger transmission depends on how much torque the engine puts out. For example, the lo-po 65hp A14 makes more torque than the 69hp A12.

One thing to watch out for in the 60-series is reverse gear. The internal linkage is weak and can bend, making it not shift into reverse properly. Wubbits and I have both run into this problem. See Will a B-210 5-speed fit in a 1200
See main article: Gearbox Weights
All 56-series and 60-series RWD transmissions are the same length. 4-speeds and 5-speeds are the same length. So they all use the same driveshaft. When fitting a 60A or 60L gearbox, there is no need to swap driveshafts.
FS5W63A and B110/B210 Automatic are slightly different length than 4-speeds. The driveshaft is 15mm longer than a 4-speed driveshaft. So obtain a 1200 automatic driveshaft.
NOTE: FS5W63A from non-B210 may be different length. Per (ROConnor): 'I hav here a 63A#1 dogleg 5-speed, and a 56A 4-speed that both measure 660mm from the mounting face to the end of the output shaft (so may be diferent 63A's?)'
Well, speedometers are generally off in the first place. But, yes, your speedo may read incorrectly if you change transmissions. On the 5-speeds, the speedo pinion gear will interchange from the 4-speed, BUT there is usually one less tooth on the 5-speed output shaft. This makes the speedo display faster than the actual vehicle speed.
Toyota 5-speeds have been used successfully by several club members. If you want to spend a little you can also get a conversion kit for a Toyota 5 speed. These boxes are stronger, lighter, more easy to find, yet less expensive than Datsun 5-speeds.

To identify a transmission, look for the series casting mark (56, 56A, 60, 63) on the left side of the gearbox, but there are many other identifying features to tell whether it is a 5-speed or a 4-speed.
Discussion about transmission differences: GEARBOX NUMBERING AND BASIC INFO.
NOTE: -L and -A do not indicate the engine type the transmission fits (bellhousing pattern). There is an FS5W63A for L16 engines, and an FS5W63A for A14 engines.
