<p>Site import</p> <p><b>New page</b></p><div>{{ImportedFrom|site=Xenonzcar|title=S30 Transmission Differences|url=http://www.xenonzcar.com/s30/transmissions.php.html|archive=https://dev.z31library.com/xenonzcar_archive/s30/transmissions.php.html|fetched=2026-05-15}}<br /> <br /> == S30 Transmission Differences ==<br /> <br /> === Manual Transmissions ===<br /> <br /> Datsun/Nissan offered several 4- and 5-speed manual transmissions for the first-generation Z cars. While a European 5-speed was available for the 240Z, it was rarely seen in the US market. It wasn’t until 1977 that a 5-speed became part of the US Z-car lineup.<br /> <br /> The 1977–1978 5-speed is a &#039;&#039;&#039;wide-ratio&#039;&#039;&#039; transmission, meaning the gear spacing is further apart. In contrast, the 1981–1983 280ZX came with a &#039;&#039;&#039;close-ratio&#039;&#039;&#039; five-speed transmission, preferred for road racing because it keeps the rev range tighter between shifts.<br /> <br /> Choosing the “optimum” transmission depends on your driving goals. For most owners, the best option is often the one already in the car. However, if you upgrade your 240Z, 260Z, or 280Z to a 3.90 or higher rear-end ratio, consider a 5-speed swap for improved highway cruising.<br /> <br /> === Manual Transmission Gear Ratios ===<br /> <br /> | Gear Ratio / Model Year | 240Z 1970–1973 |<br /> 260Z 1974 |<br /> 280Z 1975–1976 |<br /> 280Z 1977–1978 |<br /> |---|---|---|---|---|<br /> | 1st | 3.549 | 3.592 | 3.321 | 3.321 |<br /> | 2nd | 2.197 | 2.246 | 2.077 | 2.077 |<br /> | 3rd | 1.420 | 1.415 | 1.308 | 1.308 |<br /> | 4th | 1.000 | 1.000 | 1.000 | 1.000 |<br /> | 5th | — | — | — | 0.864 |<br /> <br /> === Automatic Transmissions ===<br /> <br /> In 1971, Datsun introduced an automatic transmission option for the S30 series Z-car. The model used was the<br /> &#039;&#039;&#039;3-speed 3N71B&#039;&#039;&#039;. This fully automatic unit features a 3-element hydraulic torque converter, two planetary<br /> gear sets, two multiple-disk clutches, a multiple-disk brake, a band brake, and a one-way sprag clutch.<br /> <br /> Gear changes are fully automatic based on vehicle speed and engine torque input. The transmission continuously receives signals from car speed and engine manifold vacuum to determine the proper gear ratio, ensuring maximum efficiency and performance at all throttle positions.<br /> <br /> Below are details on identifying and reading the ID plate for this automatic unit.<br /> <br /> [http://xenonzcar.com/s30/images/Differences/260zautotrannyidplate.gif image: 260Z Automatic Transmission ID Plate Location]<br /> <br /> [http://xenonzcar.com/s30/images/Differences/260zautoplateread.gif image: How to Read Automatic Transmission ID Plate]<br /> <br /> === Sources Used ===<br /> <br /> * Written by: John Walker<br /> <br /> [[Category:Imported from Xenonzcar]]</div>
