The 63a transmission is a large strong transmission. It was adapted by Nissan to fill a marketing need in USA for a 5-speed (to compete with the Corolla SR-5) and so the existing 63a was modified to fit the small A-series engine. This has two special significances:
- It is strong, suitable for overbored, supercharged or turbocharged A-series engines
- Its successor, the 60-Series Transmission 5-speed is much lighter and so a better fit for A14 and A15 naturally aspirated engines. The 60 is also smaller than 63 and so a better fit in Datsun 1200s.
The 63A came in two versions:
- 63A to fit L-series engine
- 63A to fit A-series engine
So check the bellhousing bolt pattern.
For an overview of 5-speeds in general, see: 5-Speeds. Comparos, Ratio info, etc.
Datsun boxes are numbered by the distance between the centres of the countershaft and the main shaft. The 63-series has 63 mm between the shaft centres.
The "A" indicates the transmission revision, not the engine type it fits. ? my casting has a 63A#1 cast were there different versions?
- 63A
Dogleg 5 speed overdrive 5th Slave cylinder is on the left side Uses AT prop shaft What clutch? What was the special vehicle these came out of?
- 63L
63-Series 5-speed Swap Notes
63a crossmember
Note that the factory crossmember mounting brackets have been removed from inside the tunnel. This crossmember bolts to the floor.
Get a Datsun 810 speedometer cable, it's about 150 mm longer.
You'll need a prop shaft from an AT equipped 60 series tranny as it uses the same output shaft.
