The 71 transmission is Nissan's strongest transmission. It was fitted to L-series six cylinders, FJ engines and more. 71 series comes in four different lengths, however a stumpy version is the same length as a Datsun 1200 transmission though obviously much larger around. The stronger 71B replaced the original 71A designs around 1980.
