A compact SUV launched in 2015 and cousin to the Nissan Qashqai, the Renault Kadjar has won over families with its reliability. That said, keeping the gearbox in good shape is essential to getting the most out of it. Our experts explain the best habits to adopt and what to do when something goes wrong.
Kadjar Technical Specifications
The Kadjar is available with petrol or diesel engines, including a 1.6 L TCe producing 165 hp paired with a 6-speed manual gearbox. Some engine variants are compatible with a dual-clutch automatic gearbox in 6 or 7 speeds, offering faster and smoother gear changes. On the transmission side, two configurations are available:
- Front-wheel drive: power is sent to the front wheels for better grip and improved fuel economy;
- Four-wheel drive: all four wheels are driven; a transfer case distributes power between the two axles.
Looking After the Gearbox
Monitoring the Gearbox Oil
Check the dipstick periodically: the level should sit between the two marks. If the oil is blackened or too low, an oil change is needed — every five years on a manual gearbox and every two years on an automatic.
Good Habits to Adopt
- Read the road ahead and adjust your speed accordingly;
- Don't rest your hand on the gear lever;
- Select neutral during brief stops;
- Change down through the gears progressively rather than skipping several at once.
Dealing with Faults
Describe every symptom to your mechanic (noises, vibrations, leaks, smells). The vast majority of faults can be repaired at the garage; only the most severe damage requires a complete gearbox replacement.
Shared Engineering with Nissan
The Kadjar was developed jointly with Nissan, which offers a sister model in the form of the Qashqai. Between them, the two models have sold more than three million units, primarily in Europe and China. After a mild facelift unveiled at the 2018 Paris Motor Show, the Kadjar made way for a new compact SUV, the Renault Austral, in 2022. This shared engineering means that certain transmission components are closely related to those found in the Nissan range — which is why it is important to check your gearbox reference carefully before placing any order.

Before carrying out any work on the Renault Kadjar gearbox, bear in mind that an accurate diagnosis is key to a successful repair. A professional will be able to tell the difference between normal wear and a more serious fault, saving you unnecessary expense. Take the time to note every symptom — noise, vibration, smell, difficulty selecting gears — to help your mechanic and get your vehicle back on the road as quickly as possible.
Frequently Asked Questions
Is the Kadjar available in 4x4?
Yes, in four-wheel-drive form: all four wheels are driven and a transfer case distributes the power.
How do I know if the gearbox oil needs changing?
