A compact city car born from the partnership between Peugeot and Toyota, the Peugeot 108 replaced the 107 in 2014, alongside its cousins the Citroën C1 and Toyota Aygo. Behind its urban proportions lies a straightforward gearbox that nonetheless calls for regular upkeep. EDEN BOITES explains how the Peugeot 108 gearbox works and guides you through maintaining and repairing it.
Understanding the Peugeot 108 Gearbox
The 108 was offered with 1.0 VTI petrol engines (69, then 72 bhp after the 2019 facelift) and a 1.2 PureTech (82 bhp). Two transmissions were available.
Entry-level versions come with a conventional 5-speed manual gearbox: the clutch pedal and gear lever operate the linkage, which moves the selector fork and then the sliding gear to engage the cogs. Most other models feature a 5-speed ETG5 automated manual gearbox (Efficient Tronic Gearbox). This is essentially a manual gearbox to which two actuators have been added: one operates the clutch, the other handles gear changes. A manual mode remains available, via the lever or steering-wheel paddles.
Maintaining the Peugeot 108 Gearbox
General wear, neglected servicing or an unsuitable driving style can all upset the transmission. The warning signs are typical: unusual noises, a burning smell in the cabin, or difficulty selecting gears. To prevent these issues, check the transmission fluid level regularly — proper lubrication slows component wear. Also carry out oil changes and filter replacements in line with manufacturer recommendations, and have the gearbox inspected by a mechanic to catch faults early.
Dealing with a Fault
When a fault occurs, it is important to act promptly but methodically. Repair work requires removing the gearbox to inspect it thoroughly, checking the seals for any leaks, then examining each component for signs of wear or damage. This painstaking work is best left to a properly equipped professional. On an older vehicle, the cost of such a repair often exceeds that of a replacement on an exchange basis.
Replacing the Peugeot 108 Gearbox
When replacement becomes necessary, a reconditioned gearbox offers a reliable and cost-effective alternative to a new part.

Frequently Asked Questions
What is the ETG5 gearbox on the Peugeot 108?
It is a 5-speed automated manual gearbox: a manual gearbox whose clutch and gear changes are controlled by electronic actuators, with a manual mode available.
Is the automated manual gearbox serviced in the same way as a manual?
The principles are similar: monitoring lubrication and carrying out regular oil changes. However, the automated components require a specific check of their actuators by a professional.
My 108 judders on pull-away — could it be the gearbox?
On an ETG5 model, juddering can stem from the clutch or its actuator. A diagnostic check will determine whether it is a simple adjustment or more serious wear.
Can a reconditioned gearbox be fitted to a 108?
Yes, provided you choose a reference compatible with the engine and gearbox type. EDEN BOITES can help you identify the right one.
