Open the CIPO recordAbstract From the Canadian patent
The automatic transmission comprises a torque converter and a planetary gear train. The gear train includes a first sun gear which is keyed to the output shaft of the torque converter. A first planetary gear meshes with the sun gear and that gear is keyed to an axle. The axle is mounted for rotation to a carrier and the carrier is rotated by the input shaft of the torque converter so that as the carrier rotates so too does the axle. A second planetary gear is also keyed to the axle and that gear meshes with a second sun gear. The latter sun gear rotates a drive shaft.

Why it's free to use
- Filed December 10, 1992 and granted December 8, 1998. A Canadian patent filed from October 1, 1989 lasts 20 years from filing, so its term ended December 10, 2012.
- A certificate of supplementary protection adds at most two years for a drug, so even that would have ended by December 10, 2014.
- We check Canadian rights only. A patent in its family in another country could still be in force: check its family on Google Patents.
