The P1262 gearbox is a high performance front wheel drive touring car gearbox that has been designed specifically for the Chinese Touring Car Championship (CTCC).

The P1262 benefits from experience gained during use over many seasons in the British Touring Car and World Touring Car Championships, with uprated internals specifically for the 2018 CTCC regulations. The low inertia gearchange system incorporates the latest polynomial barrel track design to improve gearchange response and driver feel. The gears have been re-ordered to allow the overlap of barrel track profiles.

The low positioning of the gear cluster enables easy removal from the car under the chassis rail, and lowers the centre of gravity. The gear cluster is fully exposed when removed from the gearbox allowing quick inspection and easy access for ratio changes.
