Summary
A New Automatic Transmission Fluid (ATF-A7) is being used for some 2023-2026 models. ATF-A7 is an extremely low viscosity formulation with low friction to achieve best-in-class fuel economy and driving performance. For easy identification, ATF-A7 is colored Red and ATF-FZ is colored Blue. ATF-A7 includes UV-reactive dye (see "Fluorescence Example" below). There is NO interchangeability between ATF-A7 and ATF-FZ. For CX-30, Mazda3, and CX-5, some 2.5L and all 2.5T engines still use ATF-FZ. Verify the type of ATF according to what is in MGSS (TRANSMISSION/TRANSAXLE TECHNICAL DATA) or what is marked on the dipstick (see "ATF-A7 Identification" below).

Owners of these vehicles have filed 61 complaints in the transmission category.
