A failed gearbox or transmission can cost $5,000–$15,000. MBI covers your drivetrain so one failure doesn't cost you everything.

Transmission and gearbox failure is among the most expensive vehicle repairs in New Zealand. An automatic transmission rebuild or replacement typically costs between $3,000 and $15,000, depending on vehicle make, model, and workshop location. Without MBI covering drivetrain components, a single transmission failure can render a used vehicle economically unviable to repair.

Common Transmission Failures Covered

MBI policies covering drivetrain and transmission typically include: automatic gearbox failure (internal components, solenoids, valve body), manual gearbox synchromesh failure, transfer case damage on 4WD vehicles, front and rear differentials, CV joints and driveshafts, torque converter failure, and dual-clutch transmission failures common in modern vehicles. Labour costs for transmission replacement alone can exceed $1,500–$2,000 before parts are considered.

Preventing Transmission Claims

While MBI protects you financially, transmission health can be preserved through: regular automatic transmission fluid changes (often neglected on used vehicles), avoiding excessive towing beyond rated capacity, appropriate engine warm-up before stressing the transmission, and addressing minor transmission issues before they become catastrophic. MBI provides the financial safety net — good maintenance prevents claims in the first place.
