Revision as of 02:20, 1 April 2014

Which transmissions bolt into the 1200, and what is involved in swapping them? Basically any B110, B210 or B310 gearbox will bolt to any Nissan A Engine, but minor fabrication is needed in some cases. In no case will a custom driveshaft be needed - if you can source the appropriate factory shaft.

Overview

Interchange

Only these interchange, meaning they can be bolted in place and used as-is with each other no matter which car they came from:

* four-speeds for A14/A15 engines
* four-speeds for A12/A13/A12A engines

The 56 and 60 series transmissions all swap with each other and use the same driveshaft - except the crossmember mounting bolt hole locations differ. Make a simple bracket to adapt the mount. The location of the Reverse Switch can differ though.

Note that this simple interchange list does not include:

emission control interchange
RHD vs LHD

See the relevant sections below

Swapping

There are several minor differences between most transmissions that prevent a strict interchange, although they can all be swapped with some additional parts sourcing or minor fabrication. Differences include:

* gearbox mount location
* reverse lamp location
* transmission length and output spline
* Strength (torque rating)
* emission fittings (top swith and/or neutral switch)
* Cable-operated clutch (most RHD) vs Hydraulic clutch

Strength

Gearboxes are rated for maximum torque (twisting force). The HP is irrelevant unless engine capacity or RPM are known, from which the torque can be deduced.

* 60-Series Transmission add lightness for best performance
  suitable for the torque of an A12 or A13 engine

* 60-Series Transmission are stronger, but heavier
  suitable for the torque of an A14 or A15

* 63-Series Transmission are larger and very heavy
  Fitted to five-speed B210 with A14 engine
  suitable for supercharged A-series engines

The 63 5-speed gearbox was designed for the 1.6/1.8/2.0 liter class, but used in the B210 because a lighter 5-speed was not available in 1976.

Sources

B10

Datsun 1000 uses 56-Series Transmission, but employ a unique bell-crank clutch release lever system. For this reason they are not swapped with other A-series engined cars.

B110

Datsun 1200 used:

* 3W56R - three-speed column shift
* F4W56L - early 1200s
  1971 USA used either the L or A type. See Hollander.
* F4W56A - lates 1200s
* FS5C56A - Datsun 1200 GX-5

B210

A12-powered
* F4W56A - B210 with A12 engine
* FS5C56A - B210 with A12 engine, five-speed

A14-powered
* F4W60 - 60-Series Transmission, four-speed
* FS5W63A - 63-Series Transmission, five-speed

B310

B310 (markedted as Datsun Sunny, 210 or 140Y/150Y) used these gearboxes:

A12/A12A/A13-powered: 56-Series Transmission
* F4W56A

A14/A15-powered: 60-Series Transmission
* F4W60 - four-speed 
* FS5W60L - five-speed dogleg shifter (1977-1979)
* FS5W60A - five-speed standard shifter (1980-1982)

A10

1977-1981 Nissan A10 ("Nissan Violet/Auster/Stanza") in Japan were fitted with base A14 engine and used the F4W60 gearbox.

Vanette

C10, C20, C22, C120 Vanette used remote shift (R) gearboxes which can be converted to floor shift (S) by swapping the rear housing.

Swap Notes

4-speeds - F4W60 fitted to A14/A15 - F4W56A fitted to A12A The mount points for the crossmember differ

5-speeds - FS5W63A fitted to B210 - FS5W60 fitted to B310 The mount points for the crossmember differ The output spline and length differs

60-series are same length both 4-speed and 5-speed. The output splines are same. Ditto for the lighter 56-series 4-speed. You need to fabricate a mount adapter to swap these in a B210. B310 came with 3 different crossmembers which will bolt to any B310 so factory parts can be used.

Driveshaft

All manual gearboxes use the same driveshaft (tailshaft), except for the 63-series. So with most swaps it is no problem.

63-series

The 63-Series Transmission is shorter and so requires a longer driveshaft. It also has larger output splines. The automatic transmission driveshaft will work when swapping this 5-speed into a 4-speed car (except for B310). See 63-Series_5-speed_Swap_Note.

Australia

Australia-assembled B110 and B210 sedans used a BW rear axle assembly, so require the matching driveshafts. For this reason when swapping to a 63-series gearbox a custom driveshaft will be required.

Emissions

Note that this simple interchange list does not include emission control interchange. Some year/model/market transmissions include a Neutral Switch or Top Switch - and some include both. For example, a Datsun 210 with same engine, same year, the transmission differs between California and Federal markets. If you need to pass emissions, be careful in sourcing the transmission.

If the transmission has extra switches, just leave them disconnected.

If you need more switches, get the right transmission. In some cases you can drill and tap the boss (if it exists) to install the switch.

Hydraulic vs Cable

Right-hand drive vehicles generally have Cable-operated clutch, while Left-hand drive cars all utlize a Hydraulic clutch system.

Exception: the B210.A14 five-speed is same RHD and LHD
Both use hydraulic clutch system

To swap the others RHD to LHD, you will need:

* Clutch Release Lever
   LHD :RHD
* To use hydraulic gearbox in cable car, cut out the lever hole
  
* To use cable gearbox in hydraulic car, cut out the lever hole
  AND drill and tap the boss to mount the slave cylinder
