Since there is still a lot of stuff about these not known exactly and many confusing topics, thousand of pages and myths, I will try here to make it easier. If anyone has additional information or something is not right, please post, then I will modify the 1 post. This is for stock factory transmissions only, NOT competition ones. There are A, B and C types transmissions ( C was never used in Z cars so I will not add these here ) Update 9/7-21 : Also the 4.11 ratio R180 was not used on Z cars ( correct me if I am wrong ) Also not sure if 3.90 was used in the USA on the 260/280Z and ZX So far I have: Nissan S30 Fairlady Z Japan till 1978: F4W71A manual F4W71B manual FS5C71A manual FS5C71B manual 3 speed automatic 3N71A 3 speed automatic 3N71B R180 Differential, possible gear ratios available: 3.36 / 3.54 / 3.90 240Z: Datsun 240Z USA and Canada F4W71A manual F4W71B manual 3 speed automatic 3N71A 3 speed automatic 3N71B R180 Differential, possible gear ratios available: 3.36 / 3.54 Datsun 240Z Europe, UK, rest of the world FS5C71A manual FS5C71B manual 3 speed automatic 3N71A 3 speed automatic 3N71B R180 Differential, possible gear ratios available: 3.54 / 3.90 260Z: Datsun 260Z USA and Canada F4W71B manual FS5W71B manual 3 speed automatic 3N71B R180 Differential, possible gear ratios available: 3.36 / 3.54 / 3.90 Datsun 260Z Europe, UK, rest of the world FS5C71B manual 3 speed automatic 3N71B R180/R200 Differential, possible gear ratios available: 3.54 / 3.90 280Z: Datsun 280Z USA and Canada F4W71B manual FS5W71B manual 3 speed automatic 3N71B R180/R200 Differential, possible gear ratios available: 3.36 / 3.54 / 3.70 / 3.90 ----- ------ ----- ------ ----- ----- 280ZX: Datsun 280ZX USA and Canada F4W71B manual FS5W71B manual 5 speed Borg Warner T5 3 speed automatic Jatco 3N71B R180/R200 Differential, possible gear ratios available: 3.36 / 3.54 / 3.90 Datsun 280ZX Europe,UK, rest of the world FS5W71B manual 5 speed Borg Warner T5 3 speed automatic Jatco 3N71B R180/R200 Differential, possible gear ratios available: 3.54 / 3.70 / 3.90 Nissan S130 Fairlady Z Japan: FS5W71B manual 5 speed Borg Warner T5 3 speed automatic Jatco 3N71B R180/R200 Differential, possible gear ratios available: 3.54 / 3.70 / 3.90

View Advert Datsun FS5W71B Close Ratio 5 Speed Transmission This FS5W71B 5 speed was removed three years ago from a low mileage 1983 280zx with its original engine. The transmission was full of oil and did not leak so the seals were left intact. When drained, the oil was in great condition and the magnetic drain plug had one shiny sliver of metal which appears to be casting flash (item #1 in the drain plug and dime pic) and two chips of magnet (items #2 and #3) stuck to it. These appear to be from the plug magnet itself- as seen in the picture that the edge of the plug magnet is missing a small piece. It shifts smoothly through all forward and reverse gears and has no friction spots or noises as the input shaft is spun by hand or drill in each gear. The input and output shaft gears themselves are also in mint condition. The aluminum case was cleaned with a nylon bristle brush and left in its unpainted original condition. The speedometer cable end is installed to protect the threads in transit. This is the very hard to find 1983 Datsun close-ratio 5 speed transmission that was only installed in the last two years of the 280zx model-1982 and 1983. It fits S110, CA18ET (200SX), L20B, L16, L18, L24, L26, L28 and L28E engines as well as MGB's with the Rivergate conversion. The '82 and '83 models have the great overdrive 0.745 fifth gear which allows for a comfortable cruising RPM even with high rear end gears. I purchased this transmission three years ago for my '71 240z project but my build has taken a different direction and I no longer need it. Here is how to positively identify this transmission model: 1. The oval block off plate with two bolts on the drivers side which is the reverse lockout (prevents clipping reverse on 5-4 downshifts). 2. A single exhaust hanger tab on the tailshaft housing. 3. No dustcover where the tailshaft exits the housing. 4. The speedometer cable connector tab machine screw is on the bottom, not the top. 5. This transmission's shifter mount has the taller 'ears' (1983 only). The good folks at California Datsun have made a video showing the differences here: https://youtu.be/UrdQZeh7GsU The auction includes the transmission with the original shift lever and shift lever pin (taped to the shifter) and the lower transmission mount as shown in pictures. It will be shipped dry, wrapped and strapped to a small pallet. Will also ship from Great Falls, Montana as we will be visiting there in the next few weeks.
