Toyota / Aisin K121 CVT transmission assembly for export — TRANSFENG Mingfeng stock

Specifications

Transmission type
Continuously variable transaxle with a starting gear — the world's first CVT to adopt a launch gear (Aisin's own description of the Direct Shift CVT). Toyota's service information treats the K120 and K121 as the transaxle systems of the same Direct Shift-CVT family.
Model codes
K121 — a code separate from the K120; Toyota's 2022 Corolla (E210) service information is titled 'Automatic Transaxle System (K120 / K121)', so the transaxle code on the unit decides which one is being supplied.
Built by / main applications
Aisin builds the Direct Shift CVT for Toyota. Aisin lists the main applicable vehicles as Toyota Corolla Sport, Toyota C-HR and Lexus UX.
Design intent (Toyota)
The launch gear handles pull-away and gives a lower first ratio, while the belt covers higher ratios; Toyota states the aim was to remove the slow response of earlier CVTs during pull-away.
Fluid service
Toyota's service information states the K120 / K121 continuously variable transaxle assembly has no oil filler tube or dipstick; the fluid level is set by the specified adjustment procedure.
Diagnostics
Toyota publishes a dedicated K121 continuously variable transaxle DTC index, and the DTC identification list changed between build periods (03/2023 – 09/2024). Confirm the build date before quoting a code list.
CVT fluid
Aisin supplies CVT fluid (CVTF) in its aftermarket range; the correct fluid for a given K120/K121 build is confirmed from the VIN before ordering.

Common applications

  • Toyota Corolla (E210) sedan, 2022 model year — Toyota service information 'Automatic Transaxle System (K120 / K121)' and 'K121 Continuously Variable Transaxle System'
  • Toyota Corolla Sport, C-HR and Lexus UX — Aisin lists these as the main applicable vehicles of the Direct Shift CVT (Aisin does not break this list down between K120 and K121, so the code on the unit has to be confirmed)

Fitment is listed for reference only — always confirm by transmission code or by sending us two or three photos of the unit before ordering.
