Changing the gearbox oil in a Peugeot 3008 is a critical maintenance task to ensure smooth shifting, optimal performance, and extended transmission life. Neglecting this service can lead to increased wear, component failure, and costly repairs. The procedure varies significantly between manual and automatic transmissions. Always consult the specific vehicle owner’s manual for the exact fluid specification, capacity, and service intervals. Personal protective equipment, including gloves and eye protection, is mandatory due to the potential for hot fluids and chemical exposure. Ensure the vehicle is parked on a level surface, the parking brake is firmly engaged, and the engine is cold to prevent burns. Wheel chocks are recommended for added safety.

For a manual transmission 3008, begin by gathering the correct specification gear oil, a suitable drain pan, a socket set, a torque wrench, and a fluid pump. Locate the gearbox drain plug, typically a large hex bolt on the underside of the transmission housing. Position the drain pan directly beneath it. Carefully loosen the drain plug with the appropriate socket, finishing the removal by hand to control the initial oil flow. Allow the oil to drain completely into the pan. Inspect the drain plug washer for damage; replace it if necessary. Clean the drain plug threads and the surrounding area meticulously before reinstalling the plug. Tighten it to the manufacturer’s specified torque using the torque wrench.
Locate the fill plug, usually positioned on the side of the gearbox casing, often higher than the drain plug. Remove the fill plug using the correct socket. Insert the tube from the fluid pump into the fill hole. Pump the new, specified gear oil into the transmission until it begins to overflow from the fill hole. This indicates the correct level has been reached. The quantity required should match the manual’s specified capacity. Reinstall and tighten the fill plug to the specified torque immediately after the overflow occurs. Clean any spilled oil from the gearbox housing and surrounding components. Start the engine, depress the clutch, and cycle through all gears before rechecking for leaks around the drain and fill plugs. Dispose of the used oil responsibly at a designated collection facility.
Changing the oil in an automatic transmission (AT) on a 3008 is considerably more complex and often requires specialized tools. Many modern Peugeot automatic transmissions, such as the EAT6 or EAT8, are sealed units without conventional dipsticks or easily accessible fill plugs. They are designed for “lifetime” fluid under ideal conditions, but fluid degradation still occurs. A partial fluid change via the drain plug is sometimes possible, but a complete exchange typically necessitates a dedicated fluid exchange machine that cycles new fluid through the transmission cooler lines. This procedure requires specific knowledge of the transmission’s fluid circulation and temperature requirements. Attempting a DIY drain-and-fill on a sealed AT often results in underfilling or overfilling, both potentially catastrophic. Furthermore, the fluid specification is extremely precise; using an incorrect fluid will damage the transmission.
Therefore, for automatic transmissions in the Peugeot 3008, it is strongly advised to have the oil change performed by a qualified technician using Peugeot-approved diagnostic equipment and fluid exchange machines. The technician will access the transmission fluid temperature via the OBD port to ensure the correct level is set during the procedure, as the level is highly temperature-dependent. They will also use the exact fluid specified by Peugeot for that particular transmission model. Incorrect fluid type, level, or procedure can lead to shifting malfunctions, clutch pack damage, and complete transmission failure. The complexity and risk associated with automatic transmission fluid service generally outweigh the potential cost savings of a DIY approach for these units.

In conclusion, while manual transmission oil changes on the 3008 are a feasible DIY task requiring mechanical aptitude and careful adherence to torque specifications and fluid types, automatic transmission servicing demands specialized equipment and expertise. For manual transmissions, meticulous execution of draining, refilling to the correct level via the overflow method, and proper plug sealing is paramount. For automatics, professional servicing is the only recommended course of action to safeguard the transmission’s integrity. Always prioritize using the manufacturer-recommended fluid and adhere strictly to safety protocols during any maintenance operation. Regular gearbox oil changes, performed correctly, are a fundamental investment in the longevity and reliability of the Peugeot 3008’s drivetrain.
