Mazda 323/626/929/GLC/MX-6/RX-7 1978-1989



Most transmission codes are available from the vehicle information code plate located on the cowl (in the engine compartment). The first portion of the code is the transmission designation; following this, there is a blank box. At the right end of the line is the axle or final drive ratio.

On other models the transmission model and serial number are either stamped on a plate that is bolted to the transmission case or stamped directly on the case itself. The location varies depending on the transmission model.

As an option on some of these vehicles, there is an electronically controlled 4-speed automatic designated R4A-EL. The transmission is computer controlled and has no owner-serviceable or adjustable components other than the neutral start switch.
