Elegant and innovative, the Renault Laguna made its mark from the 1990s onwards with its comfort and reliability. Each generation brought technological advances, including to the gearbox. Here is how to spot wear and repair the gearbox on your Laguna.
Gearbox types on the Laguna
Depending on the model and year, the Laguna was fitted with two main families of gearbox: five- or six-speed manuals, as found on the Laguna 1.8 petrol, and four-, five- or six-speed automatics, including automated manual and continuously variable variants. The architecture is broadly the same across all types: a primary shaft, an aligned secondary shaft, and a parallel intermediate shaft.
How to spot the signs of wear
- Difficulty changing gear (worn mechanism or gears);
- Transmission fluid leaks beneath the vehicle;
- Unusual noises (rattling, grinding, whining);
- Vibrations when changing gear or at a steady speed;
- A burning smell, often caused by overheating fluid.
How to repair the Laguna gearbox
Have the vehicle inspected by a professional. If you have the necessary skills, the process follows several steps: accurate diagnosis, lifting the vehicle, draining the fluid, removing the sump cover, replacing faulty components (gears, oil seals, bearings), then reassembling and refilling with the correct fresh oil.
Choosing the right replacement gearbox
Each generation of the Laguna introduced new technological advances and safety improvements, which means there is a wide range of gearbox references to navigate. To make sure you order the correct unit, note down the serial number of the part to be replaced and your vehicle's engine code before completing your purchase. The repair procedure itself follows a set sequence: diagnosis, lifting, draining, removing the sump cover, replacing faulty components, then reassembly and refilling with the correct fresh oil. A professional will ensure each of these steps is carried out correctly.

Take the time to note down every symptom — noise, vibration, smell, difficulty selecting gears — to help them work efficiently and get your vehicle back on the road as quickly as possible.
