Gearbox oil: the forgotten service that saves you thousands
If the gearbox fails, brace for one of the biggest bills a car can give you. The good news: a simple, timely oil change prevents most of those scares.
The “lifetime oil” myth
Many makers label gearbox oil as “lifetime”. In practice that’s more marketing than reality: all fluids degrade with heat and use.
“Lifetime” usually means “the car’s expected life for the maker”, not the real life you want to give it. Changing it protects a part that costs thousands. Just like with engine oil, the key is the right reference: see our gearbox oil change.
Manual and automatic: when to do it
As a guide, many manual gearboxes appreciate a change around 60,000–100,000 km. Automatics, especially torque-converter ones, feel fresh ATF a lot.
We always use the exact reference and volume for your gearbox. The wrong oil here does more harm than good.
Signs the gearbox needs oil
Listen to and feel your car:
- Hard, jerky or grinding shifts
- Jolts or hesitation in automatics
- A whine that changes with the gear
- The recommended interval has passed
Key takeaways
- “Lifetime” oil is more marketing than reality
- Manual: guide of 60,000–100,000 km
