Production2000 - present

Toyota Motor Corporation's K series of CVT transmissions found in many Toyota models. They are a pushbelt style of CVT manufactured by AISIN.

K110

Toyota's first belt-type CVT, which achieves both class-leading fuel efficiency and high driving performance; The CVT features a torque converter with a long-travel damper to help achieve quiet operation and improved fuel efficiency. Production began August 2000.

Applications:

K111

Addition of neutral-gear control and acceleration linear control to a K110 CVT base, furthers fuel efficiency improvement and high powertrain performance. Production began July 2004.

Applications:

K112

Created by increasing the capacity of the K111 CVT. Production began October 2005.

Applications:

K210

Achieve both high fuel efficiency and high powertrain performance through size and weight reductions and are perfect suited for vehicles in the 1.5- to 1.8-liter class. Production began December 2002. Later in February 2003 Toyota achieves dramatic fuel efficiency improvements through its Intelligent Idling Stop System developed by adding an electronic oil pump to the K210 belt-type CVT, ensuring excellent startup performance during engine restarts and producing class-leading fuel efficiency.

Applications:

K310 and K311

Achieve both high fuel efficiency and high powertrain performance through size and weight reductions and are perfect suited for vehicles in the 1.5- to 1.8-liter class. Production began September 2006.

Applications:

Low O/D Rev
2.386 0.411 2.505

Final drive: 5.698:1 (when fitted to 1.5L Allion & Premio 1NZ-FE and 1.8L Corolla 2ZR-FE) 5.356:1 (when fitted to 1.8L Allion & Premio 2ZR-FE)

K410

Achieves both high fuel efficiency and high powertrain performance through size and weight reductions. Designed for vehicles with engine displacements between 1 and 1.3 liters. Production began December 2004.

Applications:

Gear Ratios: Low 2.4:1 O/D 0.43:1 Rev 2.505:1 FD 5.833:1 (when fitted to 1L 1KR-FE) FD 5.08:1 (when fitted to 1.3L 1NR-FE)

K41A

Based on the K410 transmission with the differential shifted forward. Production began October 2008.

Applications:

K41B

Created by increasing the capacity of the K41A CVT, for 1.3-liter engines Production began April 2009.

Applications:

K411

Based on the K410 CVT and adopting a flex start control mechanism for the first time in a Toyota CVT; Lock-up clutch actively activated during startup to run the engine in the most efficient operating region, thereby improving fuel efficiency Production began December 2010.

Applications:

  • Several models including Corolla, Auris, Vitz, and Echo
