A Toploader transmission is a manually shifted gearbox design built in three-speed and four-speed configurations, introduced in 1963 by the Ford Motor Company to replace the BorgWarner T-10.

Renowned for high-performance strength and durability, the Toploader (particularly the four-speed) equipped such sought after "A-list" cars as the Mustang, Talladega, AC Cobra, AC Frua and Sunbeam Tiger as well as the Ford Fairlane, Falcon, Galaxie, Ranchero, Torino, Bronco and the Mercury Comet, Caliente, Cyclone, (Mercury Cougar 1967 1973) and Marauder.

The 3 speed 3.03 was also the heavy duty transmission in 1960s Oldsmobile, Buick and Pontiac cars, with FOMOCO cast into the right side of the case; sourcing parts from competitors was common practice in those days, as Lincoln used GM's Hydra-Matic transmission for years in the early 1950s.

The Jeep T150 transmission is a Toploader with the addition of a cast top cover and a floor ("cane") shifter.

Generally Falcons and Comets have shifters mounted forward along the housing, Mustangs rearward, and Fairlanes and full size Fords somewhere in between.
