All Datsun 1200s were fitted with a 56-Series_Transmission. Most Datsun 1200s come with a 4-speed floor shift manual transmission (FS4W56). Some Standard models had a 3-speed column shift (R3W56). In Japan, the special GX-5 model came with a direct-fifth (non-overdrive) 5-speed (F5W56).
Main article: 56-Series Transmission
In the United States and Canada, all 1200s had the 4-speed transmission. The 5-speed was also sold by Datsun Competition in close-ratio and wide-ratio versions.
Note that the 4-speed transmission was redesigned in April 1973. Gearsets are not interchangable between early and late transmissions.
The standard 4-speed was well suited to the A12 Engine's torque curve. With a steep 3.757 first gear and a medium-steep 3.90 rear Differential pushing small-diameter 12" Tires, it gave the little 1200 engine enough torque multiplication to take off easily, even with no throttle input. Yet top (4th) gear was good for 90mph. The 5-speed improved upon this by adding an extra gear between 1st and Top.
