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:

  • F5C56 (B110) non-overdrive a la B110 GX-5
  • F5C56A (B210)
  • FS5W63A Overdrive, JDM HB211, JDM HB310 Sunny (Coupe only), 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.

Why Should I get a 5-speed?

Adding a 5-speed is one of the best improvements that can be made to the Datsun 1200. Easier, quieter more efficient highway cruising will result. This was Mareo's idea, and I think he might be right.

Why should I not get a 5-speed?

On the other hand, if you don't do much highway driving consider that the A12 4-speed is lighter and may have less friction (meaning better fuel economy and a little more horsepower makes it to the pavement).

What types of 5-speeds are available?

  • 56-Series Transmission
    small, light as in original B110 4-speed with visible ribs along case. The 5-speed versions were 1:1 fifth-gear "direct [trans]mission" (non-overdrive) <li>60-Series Transmission
    smooth-case medium-size trans as in B310. These come in 60L (dogleg) and 60A (non-dogleg) varieties. Vanettes have the "R" version (external shifter for column shift) so it is not a feasible choice. <li>63-Series Transmission
    large trans commonly used with L-series engines, a version was also fitted to A-series engines in B210s. The 5-speed version is a "dogleg" shifter. It was fitted to 5-speed hatchbacks from 1976-1/2 through 1978 model years, and starting in 1977 for Canada</ul>

    How easy it is to swap in?


    Any A-series rear-wheel-drive 5-speed will bolt up with only slight modification.
    This means any 5-speed from a:

    • 1974-1978 B210 (120Y)
    • 1978-1982 B310 (210/Sunny).


    And, these 5-speeds are designed for the A14 and A15, so they will handle the extra torque of these motors (The A12 4-speed is a little weak to use with an A15).

    See:

    Where can I get one?

    In the USA:
    The B310 5-speed is common and inexpensive. Just look for a 79-82 Datsun 210 (Nissan body type B310 aka Sunny). You can generally find a whole car for about $500 or less. In the wreckers, transmissions go for about $150-$250. The B210 5-speeds are less common, but go for the same price if you find one. (prices last checked in 2004).

    In Australia, ask around. They can be hard to find and expensive.

    Be sure to get:
      <li>for 63-series trans, get the matching clutch disc (input splines differ) . All others are the same as stock Datsun 1200 <li>tailshaft (which may be shorter than the stock 1200 4-speed tailshaft or with different splines). The 60A 4-speeds and 5-speeds use the same driveshaft as the stock 1200 4-speed <li>The automatic crossmember (reversed) may work with some 5-speeds. In automatic 1200's, a 5-speed reportedly bolts up with the crossmember <li>The transmission mount. There are various types, so get the one with the transmission

    Shift Patterns

    Some of the trannies use a "dogleg" shift-pattern (aka 'reverse shift') and others use the standard shift pattern. The doglegs are pre-1980.

    Dogleg:

    R-2-4
    1-3-5
       10121.jpg dogleg

    Why a dogleg pattern? In racing, 1st isn't used much, but the 4-5 shift needs to be quick. <li>FS5W60L is overdrive dogleg model <li>FS5W63A is overdrive dogleg model


    Standard pattern (aka 'straight shift')

    1-3-5
    2-4-R
       hurst1630108-qkl.jpg

    The standard pattern is better for city traffic, where the 1-2 shift is used repeatedly.

    • FS5W60A is standard pattern, fitted to B310s
    • F5C56A is the non-overdrive (1:1 fifth) dogleg model fitted to the Datsun 1200 GX-5 model or available through Nissan Competition.

    Are there any close-ratio or non-overdrive 5-speeds?

    The 1984 Nissan Competition Parts catalog says:


    The 5-speed transmission (F5W56A) was originally installed on certain non-USA models of the 1200.[JDM 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).

    {EDIT} The Part Number above [3210-H7220N] does not appear in any of the JDM factory competition parts or tune up literature for the models B110 [1200] or B210 [120Y]. Without the 'N' suffix, that number describes the 56A five speed 'Option 1' close ratio competition transmission for these models. The 'N' suffix appears to be a North American addition or perhaps a variant for the US model 210 [B310 Sunny]{end EDIT} [Author KB10]

    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.

    • {EDIT} The factory 1974 Datsun B110 Competition Tune Up Manual lists only the Option 1 & 2 four speeds [56 series trans] which were superseded by the Option 1 five speed [56A trans] 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 trans] as their Option 1 gearbox & the real Option 1, the close ratio F5C56A competition trans, 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

    B210 JDM Coupes came with:
    1st 3.757
    2nd 2.374
    3rd 1.659
    4th 1.291
    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 trans. It is identical in every way to the one listed in the 1200/ B110 factory competition literature. There is no Option 2 trans listed here either. The stock B210 Sunny GX5 used the F5W56A trans.[Author KB10]

    The overdrive 5 speeds have:
    1st 3.513
    2nd 2.170
    3rd 1.378
    4th 1.000
    5th 0.875 or 0.825
    Rev 3.764

    How Strong are they?

    1278.jpg 63A Doglog 5-speed

    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.


    Datsun boxes are numbered by the distance between the centres of the countershaft and the main shaft. 56 series 56 mm, 60 series 60 mm, 63 series 63mm.

    Approximate guides are 50 % up on the stock engine torque : <li>56A 4 speeds 105 ft/lbs <li>56A option boxes 120 ft/lb <li>60 series boxes 135 ft/lb <li>63 series boxes 175 ft/lb <li>71B series boxes 240 ft/lb

    <li>71C series boxes 300 ft/lb

    Thanks to feral reference: Gearbox Strength

    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

    What about my Speedometer?

    Well, speedometers are generally off in the first place. But, yes, your speedo may read incorrectly if you change transmissions. On the US 5-speeds, the speedo pinion gear will interchange from the 4-speed, BUT there is one less tooth on the output shaft (5spd). This makes the speedo display faster than the actual vehicle speed.

    What about using a non-Nissan 5-speed?

    The Celica/Corolla T50 5-speed has 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.

    Toyota T50 5-speed

    The Toyota T50 overdrive 5-speed is light, strong and readily available. The ratios are closer than the regular Datsun 5-speeds. But you need to adapt it to the A-series engine as it uses a different bellhousing bolt pattern.

    For details, see main article: T50 5-speed

    5-speed Identification

    56-series trannies are small and light, and have these visible ribs on the case and bell section.

    By contrast, 60-series and 63-series are "smooth case" transmission with no ribs on the bellhousing area.

    60L vs 60A

    The FS5W60L is known in Japan the "low-back 5-speed" and came in the early B310 Sunny, and 1979 model year USA B310.

    • Oil plug out the back is 60L (not pointing down like 60A)
    • H90 part prefix (cast into cluster plate) is unique to this transmission
    • Unique double-gear cluster gear in extension housing is 60L
      13609.jpg
    • 60L in right-and-up position is Direct (4th) per dogleg shifter. Whereas in the 60A this same position is 5th.
    • 60L has no boss sticking out the right side of the back, whereas the 60A has it (up high).

    And who_your_datty_1200 pointed out that the #2 casting mark on the back is an indicator of the dogleg shift pattern.

    However this might be gear options or more likely just a casting revision.

    Make sure you don't purchase a 4-speed by accident :-)

    63-series 5-speed

    13612.jpg


    The 63 transmission probably came in various stock ratios. 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 1977-1978 USA got B210s with factory 5-speed transmissions. Here's an advertisement for one:

    This is the FS5W63A "dogleg" trans. Note the casting line around the center section on the otherwise smooth housing.
