The Citroën BX gearbox is at the heart of one of the chevron brand's most iconic saloons. Produced from 1982 to 1994 and sold in excess of two million units, the BX was offered with a wide range of petrol and diesel engines paired with several types of transmission. To help you find your way around and keep yours in top condition, EDEN BOITES, specialist in exchange gearboxes, is here to guide you.
From Manual to Automatic Gearbox
The earliest BX models came with a four-speed manual gearbox. As the model evolved and the engine range expanded, Citroën introduced several types of gearbox, including an automatic transmission. The gearbox transfers engine power to the front wheels by adapting torque; it is a robust component, but like any mechanical assembly it is subject to wear over time.
Identifying the Right Gearbox for Your BX
The BX's wide variety of engines means there are different gearbox references to consider. To choose the right solution, it is essential to start from the exact reference of your original transmission and engine. Our advisers will help you identify it to ensure perfect compatibility.
Recognising a Failing Gearbox
On a Citroën BX, several symptoms point to a worn transmission: stiff or imprecise gear changes, crunching noises, jumping out of gear, a low rumble that grows with speed, or oil leaking beneath the vehicle. A prompt diagnosis allows you to act before the problem worsens.
Maintaining the Transmission
Smooth driving and clean lubricant will extend the life of your gearbox. Depress the clutch fully, select neutral when stationary, allow the engine to warm up before hard use, check the oil level regularly, and stick to the recommended oil-change intervals. On an older vehicle like the BX, these simple habits make all the difference.
The Key Steps in a Gearbox Replacement
Replacing a gearbox on a BX follows a precise procedure. The technician begins with a diagnosis to confirm the source of the fault, then removes the old gearbox: disconnecting the gear linkage, removing the driveshafts and clutch where necessary. The reconditioned gearbox, selected to match the original reference, is then fitted, the clutch checked, and the unit filled with the recommended lubricant. A road test is carried out to verify smooth gear changes. Entrusting this work to a specialist ensures a reliable installation and performance in line with the original specification.
Repair or Exchange?
When wear is too advanced, an exchange gearbox offers a dependable solution: the unit is fully reconditioned, its wear parts replaced, and its operation verified. Explore our range in the Citroën collection.

Staying on Top of Your Mechanics
The gearbox in your Citroën BX is no mystery: a few basic habits are all it takes to keep it in good shape. Regular oil checks, a gently operated clutch, and an ear tuned to unusual noises will help you anticipate most problems. If a symptom persists, a quick diagnosis is always better than a costly repair down the line. And if wear has taken its toll, an exchange gearbox remains the surest way to restore a reliable transmission, selected precisely to match your vehicle's reference.
