What makes the Mazda B2500 so special?

The Mazda B2500 is powered by a 2.5-liter SOHC turbodiesel engine with two power levels: 84 hp, as found on the 2.5 TD PICK-UP 4X4 , or 110 hp, as found on the 2.5 D PLATEAU RIDELLE 4X4.

The B2500 features a five-speed manual gearbox with either rear-wheel drive or all-wheel drive. In the latter case, the rear wheels are driven, and all become so when the driver activates the front axle.

The single cab is available in 2WD or 4WD versions, while the extended cab is produced exclusively with two-wheel drive. The Freestyle and double-cab models are equipped with engageable all-wheel drive with off-road reduction. All models feature a limited-slip rear differential for enhanced traction on slippery terrain.

What is Mazda B2500 transmission oil used for?

Transmission oil is fundamental to the smooth operation of the gearbox: 

  • It lubricates internal gearbox components such as gears, pinions, bearings and clutch plates to prevent friction and optimize fluidity;
  • It prevents the transmission system from overheating by dissipating the heat generated by moving parts;
  • It keeps the system clean by removing any dirt that may accumulate in the transmission;
  • Its anti-corrosive and anti-oxidant properties protect box parts.

To ensure that the transmission oil plays its role correctly, it's important to check its appearance and level regularly, using the dipstick generally located on the side of the oil sump. For mechanical gearboxes such as those fitted to the Mazda B2500, an oil change is recommended after 250,000 kilometers.

How do I know if my transmission system is malfunctioning?

The first sign of gearbox failure is difficulty shifting gears, manifested by resistance on the clutch pedal or gearshift. Vibrations may be felt while driving: this symptom may indicate an unbalanced or out-of-phase driveshaft, a damaged flywheel, worn bearings or pinions.

When a burning smell appears, it's very likely that the transmission oil is insufficient: don't delay to top it up or change the oil to avoid advanced wear of your gearbox components.

A drop in overall vehicle performance or an inability to shift gears indicates major damage: don't delay in contacting a mechanic who will be able to make a precise diagnosis of the fault. He will confirm whether your gearbox needs to be repaired or completely replaced.
