TOYOTA K210 / XA-15LN

Simultaneously with the first generation of CVTs (K110/K111/K112), the Japanese company Aisin designed a lightweight CVT version K210 intended for small cars (with engine capacity of 1.0-1.5 liters). The right-hand drive Toyota Vitz (engine capacity 1.3 liters) was the first car equipped with this CVT. This car was intended for sale on the domestic market of Japan. Toyota wanted to test this CVT in Japan and fix all possible issues. The first upgrade of K210 was implemented in 3 month after its launch – Aisin engineers changed the belt. This measure helped to improve the car performance reliability at idle speed. In 2004, CVTEC Co., Ltd started production of 30-millimeter CVT belts, which found application in K210 (before that, the K210 gearbox was equipped with the belt of the Dutch company VDT BV).

For the external market (car models not including Toyota), Aisin produced the modification of K210 named as XA-15LN. From 2007 to 2014, this CVT had been successfully used by the company Mazda in its cars (Mazda Demio and Mazda Axela). It should be noted that modifications of the K210 transmission are not interchangeable (or partly interchangeable).

The range of K210/XA-15LN did not receive any continuation. CVTs of this series were installed on a limited number of models of Toyota and Mazda for the domestic market of Japan. These CVTs had been produced before the end of 2015.

In 2004, Aisin developed a new range of CVTs (K410/K411) for Toyota cars with 1.3-1.5 liter engines. This series turned out to be quite successful.

Typical problems:

1) CVTs of K210/XA-15LN series (as well as other CVTs produced by Aisin) are extremely sensitive to ATF quality. In this case, we are talking not only about the presence of metal shavings in ATF, but also about ATF overheating. Shavings in ATF are actually abrasive particles, which eventually (if ATF is not changed) damage Teflon rings in CVT. Then it leads to ATF pressure drops in the transmission itself. Severe wear of Teflon rings over time leads to damage of friction clutches and steel discs.

2) Overheating of the CVT K210/XA-15LN often leads to complete replacement of friction discs. If the driver continues using the transmission with burnt ATF for a long time, then ATF not only loses it qualities and cools the transmission insufficiently (often it leads to overheating and replacement of pistons), but also poorly lubricates cones (especially in winter mode). It leads to slipping of the belt in winter time. Early versions of K210-11A CVT modifications were equipped with belts of the company VDT BV. These belts are not interchangeable with later modifications of belts produced by “CVTEC Co., Ltd.”.

3) Shavings (if ATF is not changed) reach bearings on the input and/or output shaft of cones and eventually one of bearings starts “buzzing”. Bearings are not very expensive, but replacement of

the “buzzing” bearing is possible only with removal and complete disassembly of CVT (this procedure is time-consuming).

4) Some drivers had to deal with the problem of seal leakages in K210. Replacement of seals is usually combined with ATF change
