AUTOMATIC TRANSAXLE 

AUTOMATIC TRANSAXLE OUTLINE

AME561401030A01

• Adopted new JA5A-EL automatic transaxle.

• Newly designed FF type five-speed automatic transaxle.

— Use of 3 sets of planetary gears, and wider gear ratio setting realizes improvements of acceleration-from-

standing-start performance, fuel economy, and quietness. Also, by placement of two sets of planetary 

gears in parallel with one set, the automatic transaxle is more compact.

• Adopted 2-4 brake clutch.

— Adopted a wet-type, multi-plate 2-4 brake clutch instead of the 2-4 brake band used in the past, smoother 

gear switching performance.

• Adopted centrifugal balance clutch

— The newly adopted centrifugal balance clutch pushes the clutch piston forcefully to low and high clutch by 

centrifugal hydraulic pressure for smoother gear switching with better response.
