The F5C56 is a 5-speed transmission used in the 1972 Datsun 1200 [[GX5]], and also in 1973-1975 A12-powered Datsun B210s. All version are marked '56A' on the side of the case although the factory parts catalog C-260 says 'F5C56'. This is the 56-Series 5-Speed '''FS5C56''' &quot;lo-back&quot; wide-ratio transmission, which is just about perfectly matched to the [[A12GX_Engine|A12GX Engine]] for street and highway use. It is a dogleg design for quick 2-3 shifts. It is a direct fifth design for superior acceleration instead of overdrive for fuel economy. In addition to the dogleg shift pattern, it is equipped with Porsche-type &quot;competition&quot; [[Synchros|synchros]].

The 56-series five speed is a Dogleg shifter:

Why a dogleg pattern? In racing, 1st isn't used much, but the 2-3 shift needs to be quick.



NOTE that 60L and 63A A-series 5-speeds are also doglegs, but are overdrive transmissions. F5C56 is the only non-overdrive type.

= Overview =



The 56-series transmission came factory stock in Datsun 1200 [[GX-5]] models and in B210 JDM. They were also sold by Datsun Competition. This means they are very rare and hence expensive.



<span id="26366" class="imagepx" style="width:400px; rotate:0deg; ">[[File:26366.jpg|200px]]<span class="album_overlay">[[:File:26366.jpg|Album 26366]]</span></span> <span id="26660" class="imagepx" style="width:400px; rotate:0deg; ">[[File:26660.jpg|200px]]<span class="album_overlay">[[:File:26660.jpg|Album 26660]]</span></span>



The B210 version 5-speed (for A12T) used an engine plate instead of a simple dust cover. See [[Clutch#Rear_Engine_Plate|Engine Plate]]



The advantages of the 56 over other 5-speeds is:



* It is non-overdrive, and hence desirable for certain types of racing

* It is a dogleg shifter (as is the 63A and 60L for A-series engine) for quicker 2nd-3rd shifts

* It is lighter, aiding acceleration

* It is smaller, fitting perfectly into the tunnel

* It bolts into any Datsun 1200 using factory parts. The other 5-speeds need slight modifications



These boxes don't have a great reputation for strength behind the A14 or A15 motors, but are excellent behind an A12. They are marginally OK for use with A13, although the TS racers had to treat them with great care. NOTE they do fit the smaller tunnels in the Datsun 1000.



The 'standard' Datsun 1200 competition engine used a 76mm bore yeilding 1270cc This is the standard [short stroke] A13 dimension &amp; capacity. Serious competition engines ran even larger bores with capacities only a few cc's under 1300. The Option 1 five speed was the recomended transmission behind these factory spec race engines. Source. Datsun B110 Competition Tune Up Manual, 1974



The [[#Factory_Crossmember|#Gearbox Crossmember]] is slightly different from the 4-speed crossmember.



Reverse gear is the only moveable gear in a 56-series gearbox -- it slides back and forth to engage or disengage.<br />

Look for '56A' on the right side of the box. This IDs 56-series 4-speed or 5-speed<br />

The most sure-fire IDs for the 5-speed:



* The top case bolts are long (2-3&quot; long)

* Reverse gear detent plug in on left side

* Reverse light switch on top, pointing straight back

* Drain plug straight down



5-speeds are RHD only (clutch hole on right-side, and right-side cutout for clutch lever). 4-speeds are available RHD or LHD.

'''Question''': isn't it the best way to know if it is a 5-speed is to mover the shifter knob into the &quot;fifth gear&quot; position?



'''Answer''': This has mislead many a buyer. Many a 4-speed appears to shift into a 5th position but there's nothing there... One method to determine if a 56A gearbox is a five speed is to move the lever to the left. If a spring detent is felt, then press against it, overcoming its resistance, &amp; move the lever forward. Turn the input shaft by hand &amp; the output shaft should rotate in the opposite direction. If it does, then it's a 5 speed.

To fit the 56-series 5-speed,the 4-speed FS4W56 [[Gearbox_Crossmember|Gearbox Crossmember]] can be used with 20 mm spacers between the body mount and the crossmember.

The original drain plug for the GX-5 gearbox was a taper-thread plug as expected, but with a hex-head instead of the more common square-headed plug.<br />

Because it goes in the adapter plate, if tightened &quot;normally&quot; the adapter will crack (hence why it is called the fragile &quot;glass transmission&quot;).<br />
