Transmission general data

TOYOTA K310 / K310F / K311 / K311F / K312 / 313

In 2006, Aisin started production ofCVTs of the K310/K311 series. From Toyota’s perspective, this gearbox was a great option for 1.5-1.8 liter gasoline engines. In November 2008, Toyota cars (Toyota Avensis and Toyota Verso), equipped with the K311, appeared on the European market. In 2012, Aisin improved these CVTs (primary from the point of view of fuel economy) and released a new CVT of this family named as K312/K313.

Earlier, each Toyota car model was equipped with a particular CVT from the beginning till the end of its production cycle. With regard to CVTs of “300” series the situation changed. In fact, the K310 CVT model was manufactured until 2015. However in 2012, more modern CVT K313 replaced K310 on some car models (for domestic market). In 2015, Toyota models (Toyota Avensis and Toyota Verso) for the European market were equipped with the K313 CVT instead of K311. The same changes concerned Toyota Corolla.

Typical problems of These CVTs are similar to issues which occur in the “200” series (ATF contamination, overheating, damage of bearings, seal leakages).
