The MGC had an all-synchromesh gearbox like that of the late MGB models. It also shared the same ratio as the MGB on non-overdrive units, bsut with overdrive, there was a closer ratio.
This tighter gear ratio was carried over from the 1969 models onwards. An optional Borg-Werner 35 three-speed epicycle automatic gearbox was also offered. It could be identified by the gearbox prefix 17EA. The clutch was of 9” diameter, and the hydraulic actuation was provided by a Girling 0.625” master cylinder, with the integral reservoir at the very rear of the cylinder.
