Prepare the Vehicle

Park the Mazda CX-5 (PYB2C) on level ground, disconnect the battery, and safely lift the vehicle using a hoist or jack stands to gain access to the transmission system.

Remove Old Gearbox

Drain all ATF fluid completely, then disconnect the wiring harnesses, cooler lines, and mounting bolts before carefully lowering and removing the existing gearbox.

Install the Reconditioned FZ21

Position the refurbished FZ21 transmission with a transmission jack. Replace all worn seals and torque every mounting point according to OEM specifications to ensure proper fit and alignment.

Reconnect Components

Reconnect the wiring harnesses, sensors, and TCU connections. Double-check that all plugs are fully seated to prevent electrical or diagnostic errors.

Fill with ATF Fluid

Refill the system with Mazda ATF M-V fluid, adjusting the fluid level based on the manufacturer’s service temperature guidelines for accurate performance.

Programming & Adaptation

Use a Mazda-compatible diagnostic scanner to perform TCU adaptation and ECU calibration. This ensures smooth gear changes, optimized torque delivery, and consistent driving performance.

Final Road Test

Conduct a road test under both city and highway conditions. Confirm smooth gear engagement, stable acceleration, and reliable ATF pressure during various driving scenarios.
