While Honda has remained tight-lipped about where else the 10-speed unit will end up, sources believe the switch makes financial sense because the nine-speed unit is bought in from ZF, where as the 10-speed has been developed in house by Honda Precision Parts in Georgia.
Honda said at the Odyssey’s reveal in Detroit that the 10-speed offers “outstanding driveability” and improved economy. The gearbox will at first only be offered in higher-spec Odysseys, with the nine-speed featured in lower models. But Honda admitted production of the 10-speed will increase over time, supporting information that it could replace the nine-speed altogether.
Mercedes has recently dismissed the idea of producing its own 10-speed gearbox, stating that nine speeds was the most it would offer in its road cars. But Ford launched its new F-150 with a 10-speed and General Motors has confirmed development of its own 10-cog item, suggesting more brands could follow suit.
