From the great shifting manuals used in the MX-5 Miata, fuel efficient CVTs used in their crossovers and traditional automatics available in almost all their cars, there have been a wide range of drivetrain choices in Mazda’s lineup. Each has their unique problems, but no matter which type of Mazda transmission repair you need, River City Transmission can get it working again.


What Can Go Wrong with My Mazda’s Transmission?

Over time, synchros in a manual transmission can wear down, making it hard to engage the gears. Your Mazda may have clutch repair issues including the clutch itself as well as the throw out bearing, flywheel, and the hydraulic or cable system linking the transmission to the clutch pedal.

Mazda Transmission Repair and Clutch Service in NE and SE Portland ORAutomatic Mazda transmission repair can get more complicated, since the driver-operated shift mechanism is replaced by a series of clutches and servos operated by a computer. Problems can arise from something anything from low fluid levels to failed internal components.

A CVT uses a reinforced belt riding on two pairs of cone-shaped sheaves that can move in and out, changing the belt’s position to alter the drive ratio. This is a lot simpler than a regular automatic, but failures in the tension springs, belt and control system can bring your car to a halt.
