Toyota Motor Corporation's RC family is a family of 6-speed RWD/4WD transmissions. The RC transmission uses an output reduction method to achieve a compact construction. A double overdrive (5th and 6th gears) is used. A multi-cone synchromesh mechanism is used for 1st, 2nd, and 3rd gears to improve shift feel. Similar in some aspects to the older RA transmission, the RC features a separate clutch housing and uses a steel release bearing sleeve to improve serviceability and service life.
