Designed to transfer engine power to the wheels, the Peugeot 4008 gearbox is essential to the smooth running of this crossover. Crunching noises, difficulty selecting gears, transmission oil leaks — these warning signs should never be ignored. EDEN BOITES explains how to diagnose, maintain and replace the gearbox on your Peugeot 4008.
Peugeot 4008 gearboxes
Launched in 2011 and sold until the end of 2016, the 4008 was built on a platform shared with Mitsubishi and Citroën. Several transmission options were offered depending on the engine. The 1.6 HDi FAP 115 bhp and 1.8 HDi FAP 150 bhp diesel engines come with a 6-speed manual gearbox. On petrol variants, the 1.6 and 2.0-litre engines are fitted with a 5-speed manual gearbox, while a CVT automatic gearbox was a common option throughout the model's life. Identifying the correct version is essential: the transmission architecture varies and determines parts compatibility.
How do you repair the 4008 gearbox?
The repair approach depends on the nature of the fault, as the work differs between manual, automatic and CVT gearboxes. Just as a doctor diagnoses before treating, the root cause of the problem must be identified before any work begins. This step requires an experienced mechanic.
An oil change is necessary when the transmission oil is contaminated: a build-up of deposits impairs the components and often results in difficult gear changes and crunching noises. Faults can also stem from worn internal components: the technician will then inspect the mountings, look for signs of damage or corrosion, and assess the overall behaviour of the gearbox.
When should the gearbox be replaced?
Because a single symptom can have several causes, repairs vary in complexity. When the damage is severe, replacement becomes the safest solution: a repair does not always guarantee the longevity of the part, or your safety. A reconditioned gearbox is then a sound long-term investment, provided you choose a quality, compatible reference. Browse our range in the Peugeot gearboxes collection.
