"The Ford Toploader transmission is a manually shifted three and four speed gearbox introduced in 1964 by the Ford Motor Company to replace the BorgWarner T-10. It was used in most Fords and Mercurys from 1964 until 1973 as well as some foreign models. Officially designated the 3.03 three speed or Ford design four speed, the Toploader got its name from the fact that the access plate to the inner workings was located on the top of the main case as opposed to the side, a convention used on most gearboxes such as the Ford Dagenham or GM's Saginaw or Muncie. This feature increased the rigidity of the case significantly. Distinguishing the three speed from the four is as simple as counting the fasteners on the top plate. The four speed has ten; the three, nine. Both the three and four speed top loader gearboxes were designed to function in constant mesh, due to synchronizer sleeves being used instead of sliding gears, and be fully synchronized, with the exception of reverse. Forward gears are helical-type while reverse gear including the exterior of the first and second synchronizers sleeve are spur-type gears. This transmission is also known as the Tremec T-170, HEH, or RUG depending on the year(s) of production."
