Datsun Manual Transmissions F4W71A and FS5W71A and Automatic 3N71A
The 1970-1971 Datsun 240z USA model came with a 4-speed manual transmission designated as F4W71A. The FS5C71A was a 5 speed manual transmission version, not available in the US! These transmissions are the easiest to identity. It has 3 piece case and the shifter is raised above the transmission.
The Automatic transmission 3N71A did not come in the US Datsun 240z, but I wanted to provide some information. Im not sure what Nissan did to redesign the “B” model, 3N71A.
