Which manual transmission was standard in the AMC Rebel Machine?

The Borg-Warner T-10 four-speed manual was standard in the AMC Rebel Machine. It used a Hurst floor shifter and sent power through AMC’s Twin-Grip limited-slip differential.

The standard transmission was part of The Machine’s performance-focused specification. Buyers also received power disc brakes, heavy-duty suspension, wide Goodyear Polyglas tires, and a 15-by-7-inch set of Machine-style steel wheels. Rear axle ratios of 3.54:1 or 3.91:1 could complement the four-speed’s acceleration-oriented character.

The Borg-Warner T-10 was a widely used American high-performance manual transmission, appearing in numerous muscle cars during the 1960s and 1970s. It is easy to confuse it with the Ford Toploader, Chrysler A833, or GM’s Muncie gearboxes, but those were different transmission families.

An automatic transmission was available as an alternative, but it was not the standard manual equipment asked about here. The four-speed, Hurst shifter, and strong rear axle made the Rebel Machine’s drivetrain central to its muscle-car identity.
