Revision as of 02:06, 12 January 2007

The 56-series is the stock Datsun 1200 transmission. It was fitted to all RWD B-series Datsuns with A12 and A13 engines. Standard models used 3-speed 56s, while most models used 4-speed versions. The Datsun 1200 GX-5 used a 5-speed version. It was designed to handle the torque of an A12 or A13, but for A14 and A15 engines a 60-Series Transmission is recommended.

4-Speed

The stock sport transmission is fine for city driving. It has wide-spaced gears to allow a steep 1st for easy takeways.

Option 1 Middle-Close Ratio

The option #1 (middle-close) gear set alleviates the 2nd-into-3rd RPM drop that exists with the stock 4-speed. It can only be installed into 1200 transmissions (F4W56L) built up to 3/73.

5-Speed

For an overview of 5-speeds in general, see: 5-Speeds. Comparos, Ratio info, etc.

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

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 63 and 60L for A-series engine)
• It is light and small
• It bolts into any Datsun 1200 using factory parts. The other 5-speeds need slight modifications.

The 5-speed transmission (F5C56A) was originally installed on certain non-USA models of the 1200. 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).

56 5-speed swap Notes

When installing the F5C56A 5-speed transmission in the 1200, B210 or 210 models an alternate transmission mount, insulator and stopper must be obtained. The 210 mount requires 20mm/.787" spacers for correct driveline alignment.
