The gearbox of the Fiat 500 Abarth 695 Biposto is no ordinary unit: unveiled at the 2014 Geneva Motor Show, this Abarth is the most extreme ever to leave the factory. Stripped of its rear seats (hence the name "Biposto" – two seats), it borrows heavily from motorsport while remaining road-legal. Its transmission is put under intense strain, in keeping with its track-bred character.
Suspicious noise, or a gear that won't engage cleanly? Don't worry. EDEN BOITES shares its expert advice to help you understand and repair the gearbox on your Fiat 500 Abarth 695 Biposto.
Two gearboxes for the 695 Biposto
Powered by the 1.4 Turbo-Jet tuned to 190 hp, the Biposto comes with a 5-speed manual gearbox. Its real talking point, however, is an option straight from the racetrack: the famous dog-engagement gearbox, topped with a long aluminium gear lever adorned with the scorpion badge. Understanding the difference between these two transmissions helps pinpoint any potential problem.
The traditional manual gearbox
Here, the clutch disengages the engine from the gearbox while changing gear. Synchronisers match the rotation speeds for smooth shifts, and the gears then transmit power to the wheels. It is a tried-and-tested mechanism, forgiving and well suited to everyday use.
The dog-engagement gearbox
More extreme in nature, it uses dog-engagement gears that mesh directly, without synchronisers. Gear changes are ultra-fast but more abrupt, and the clutch is used almost exclusively for pulling away and coming to a stop. Less prone to synchro wear, it does however demand real skill to use considerately on the road.
Spotting the early warning signs of a problem
Whatever type of gearbox your Fiat 500 Abarth 695 Biposto is fitted with, staying alert is the best form of prevention:
- listen for noises: grinding, whistling or metallic clunking are signs of a developing problem;
- test the gear changes: juddering, catching or refusal to engage all point to a fault;
- watch for leaks: any trace of oil around the gearbox indicates a failing seal or gasket;
- note any anomalies: a warning light or loss of power may be related to the transmission.
At the first sign of concern, have a thorough diagnostic carried out by a specialist. You can also browse our gearbox collection right now.
Repair or replace the Biposto's gearbox?
You own an exceptional car – it deserves exceptional care. Minor wear can sometimes be addressed with an oil change and the replacement of targeted components. When wear is severe, however, replacing the gearbox becomes the safest solution.
An exchange gearbox lets you get back on the road on a solid footing: your old unit is taken back, and a reconditioned, tested unit takes its place. This is often the best balance of reliability, turnaround time and cost. Find the right references in our Fiat catalogue.
Frequently asked questions
Can the dog-engagement gearbox be repaired?
Yes, but it requires genuine expertise. Depending on the condition of the dogs and gears, a rebuild or an exchange unit will be recommended following a diagnostic.
Why does my Biposto crunch when downshifting?
On a synchronised gearbox, this points to worn synchronisers; on a dog-engagement gearbox, a shift that is poorly matched to engine speed is enough to cause the noise.
Is a specific oil required?
Every gearbox requires an oil that meets its specified requirements. A professional will select the right lubricant for your configuration.
