Mazda M5OD transmission

From Wikipedia, the free encyclopedia

The M5OD (Mazda 5-speed with Over Drive) is a line of transmissions produced by Mazda and used in Mazda and Ford cars and trucks. Light-duty R1 and medium duty R2 are used. R1 transmissions are/were used in the Ford Ranger, Explorer, Aerostar, and Bronco II. R2 versions are/were used in the F-150, Econoline Van, full size Bronco and Cougar/Thunderbird Super Coupe.

The M5OD features fully synchronized on all gears, including a reverse gear. The concept of synchro on reverse gear was one of the main features of the new units, to protect internal components to be damaged by inadvertent operation by the customer, being protected by US Patent: 4,757,726. The transmission has an integral bellhousing, making the power plant stiffness high enough to avoid harmful resonance. The transmission uses a hydraulic clutch setup and has an internal slave cylinder.
