The W-series is a 4-speed or 5-speed manual transmission built by Aisin. It is a super strong transmission which will just fit in the Datsun 1200 transmission tunnel.
Contents |
Overview
Toyota W transmissionᵂ by Aisin. About 90 pounds. W can handle 300-350 ft-Lb torque. If your engine makes more torque, use the larger heavier Toyota R transmissionᵂ. The R154 can handle 450-550 ft-Lb torque.

Swap Notes
3Rotor and Cameron_Datto have fitted W gearboxes to Datsun 1200.
To adapt to the Nissan A Engine use one of the following methods:
- Cut & Shut
- Adapter Plate
- A-series bellhousing (custom order from Dellow Conversions in Australia)
3Rotor: remove the cross-member mounting pods in the tunnel, open up the shifter hole a bit at the back (no other tunnel mods needed). Cameron had do to "some heating & beating" in the tunnel

Cut-n-Shut
racinaround cut the front 3" off a FWD SR transmission, then welded it to the Supra gearbox. This is handy because Nissan doesn't make RWD 5-speeds that fit the FWD SR engine.
Steel Case W50
W50 is the steel-case version of the W gearbox. It does not interchange with the W55-W50 alloy case models.
W50 Adapter Kit
Reportedly, Dellow Conversions offers a kit to bolt up a W50 to a Datsun A-series engine.
W50 Adapter Plate
The W50 Toyota 5-speed can be fitted to a Datsun A-series engine. Use an A-series automatic transmission bellhousing with an adapter plate to fit the W50 gearbox. The W50 is a non-alloy gearbox, and the thickness of the adapter plate would be different for any alloy W gearbox.
Bare adaptor plate to suit an A series auto bell housing and a W50 steel case Celica 5 speed
Adaptor plate bolted to Celica box, clutch fork pivot fitted.
Datsun 56A 4-speed verses a Celica W50 steel case 5-speed fitted with an A series auto bell housing and adaptor plate.
Above: A series 56A 4-speed
Below: W50 Celica 5-speed below. Modified Datsun clutch fork fitted to Celica thrust bearing. Slot cut through the side of an A series auto bell housing . Clutch fork retaining spring and clutch cable mount still to be made.
The input spline lines up exactly
The spigot fits into the back of the A-series crankshaft as per standard but a machined spigot bearing needs to be made to suit the Celica input shaft.
Mods need to be made to the clutch fork, and thrust bearing carrier
A new cross member needs to be made, the tunnel needs a bit of a massage
The speedo cable matches up to the Celica box with no mods.
A clutch needs to be sorted out, a new spigot bearing needs to be made, and a new tailshaft is needed.

Clutch
Some W's use the same spline/diameter input shaft as the Datsun A. So the Datsun clutch disc fits
Other W's use a larger 1-1/8 shaft with 18-splines. For this you may be able to re-drill the A-series flywheel to take one of the smaller clutches.
