Powertrain Transmissions

Automatic Transmissions

• Depending on the installation position of the engine different types of automatic

transmissions are used. Vehicles with transversally installed engine feature an ATX

(Automatic Transaxle) and vehicles with longitudinally installed engine an AT (Automatic

Transmission). The basic difference between ATX and AT is that the ATX has a

differential integrated in the transmission housing, while the AT has an external

differential at the rear axle. For the current European Mazda models only ATX are

available.

• The ATX fitted in the current Mazda models have the following features:

– Four, five or six speeds

– Two or three single type planetary gear sets, or a single type planetary gear set in

combination with a Ravigneaux planetary gear set

– Hydraulically controlled clutches, brakes and brake bands

– Torque converter with torque converter clutch

– Electronic control system integrated in the PCM or in a separate TCM

• The following ATX are fitted in the current Mazda models:

Model / ATX FN4A-EL FS5A-EL AW6AX-EL

Mazda3 X

Mazda6 X

Mazda CX-7 X

L1001.4_T02005

NOTE: All the automatic transmissions are very similar in operation and servicing.

Therefore, this section only shows one sample of the current automatic

transmissions.
