Used Mazda Premacy Differential

The Mazda Premacy was sold in the UK across two distinct generations: the first generation (CP) ran from 1999 to 2005, and the second generation (CR) ran from 2005 onwards. A differential from one generation is very unlikely to swap directly into the other, as the platforms, drivetrains and subframe geometry differ significantly across that 2005 boundary. Your best starting point is to confirm your engine code from your V5 or a VIN check, then ask the breaker to match on generation and engine code rather than year alone.

Fuel type directly affects the differential specification because the torque output and gearing requirements differ between petrol and diesel engines, so a petrol differential is not a straight swap onto a diesel driveline and vice versa. Engine code is the most reliable way to identify which differential your vehicle needs, and you should supply that to the breaker rather than relying on fuel type alone. Confirm the match with the breaker against your registration before purchasing.

Yes, gearbox type is a key fitment factor for the differential because the final drive ratios are typically different between manual and automatic variants. Always tell the breaker whether your car is manual or automatic alongside your engine code, as supplying one without the other could result in the wrong unit being sourced. Never assume a differential from the opposite gearbox type will interchange, even within the same engine family.

Trim level does not affect differential fitment on the Mazda Premacy; the TS and TS2 are specification grades that differ in equipment and interior features, not in drivetrain components. As long as the engine code, fuel type, gearbox type and generation match between the donor car and yours, the differential itself should be the same unit. Bear in mind that ancillary brackets or mounting hardware can sometimes vary mid-production, so confirm the full specification with the breaker against your registration before buying.

This question crosses the generation boundary between the first-generation CP Premacy (1999–2005) and the second-generation CR Premacy (from 2005), so the answer depends on exactly which generation each car belongs to. If both vehicles are genuine first-generation CP cars with matching engine codes and gearbox types, there is a reasonable chance of compatibility, but if the donor is an early CR you should treat them as non-interchangeable without expert verification. Route this directly to the breaker, supplying both engine codes, so they can confirm whether the units are the same specification.

Mileage and condition do not affect whether a differential will physically fit your Premacy, but they are very relevant to how long it will last once fitted. When contacting a breaker through Findapart, ask about the donor vehicle's mileage, whether any noises were present before the car was dismantled, and whether any warranty is offered on the unit. A lower-mileage differential from a specification-matched donor car is always preferable where one is available.
