The Fiat Sedici's gearbox is the product of an unusual collaboration between Fiat and Japanese manufacturer Suzuki. This compact crossover, produced from 2006 to 2014 and a close cousin of the Suzuki SX4, attracted nearly 76,000 buyers, particularly in Italy. Its shared mechanical architecture results in several transmission types that are worth knowing about.
Originally, the Fiat Sedici was offered with two engines: a Suzuki 1.6 16V petrol unit and a Fiat 1.9 8V diesel. The 2009 facelift retained both engines while boosting their output — the Suzuki unit rising from 107 to 120 bhp and the Fiat from 120 to 135 bhp. EDEN BOITES, a specialist in gearboxes in France, explains everything you need to know.
Three Gearboxes for the Fiat Sedici
Early Fiat Sedici models came exclusively with a five-speed manual gearbox, more than adequate for engines limited to 107 and 120 bhp. Fiat subsequently decided to fit certain versions — mainly the diesels — with a six-speed manual, better suited to the generous torque of those engines.
From 2009, the Fiat Sedici was also offered as an option with a four-speed automatic gearbox. This provides extra comfort, particularly in town, though it does come with a slight reduction in top speed. For a clear understanding of the differences between these options, our guide on manual and automatic gearboxes makes for useful reading.
Keep an Ear Out for Your Fiat Sedici's Gearbox
Robust as it is, the Fiat Sedici's gearbox requires constant attention. Unusual noises — grinding or rattling — are often a sign of worn gears or low transmission fluid. Whether manual or automatic, the gearbox needs proper lubrication to function correctly.
It is therefore important to check the transmission fluid level regularly, top it up as needed, and carry out periodic fluid changes. There are other warning signs to watch out for:
- a gear that won't stay engaged or becomes difficult to select — a possible sign of worn gears or synchromesh rings;
- a loss of power caused by faulty gears;
- oil pooling beneath the vehicle;
- a warning light appearing on the dashboard.
Taking these symptoms seriously as soon as they appear will very often prevent a costly repair further down the line.
What to Do When Your Fiat Sedici Gearbox Develops a Fault
A fault in the manual or automatic gearbox of your Fiat Sedici can have several consequences: reduced performance, uncomfortable driving, premature wear of components, increased fuel consumption, and — not to be overlooked — a genuine safety risk and the danger of a breakdown.
It is therefore important to act quickly and, ideally, to entrust the repair to a professional. If you feel you have the necessary skills, bear in mind that on the Fiat Sedici the gearbox is located in the engine bay. You will need to raise the vehicle, remove any obstructing components, and then carefully lower the gearbox out.
You can then inspect it: start by checking the seals for any leaks, then examine the components for signs of wear or damage. Once the faulty part has been identified, replace it and reassemble everything. If in any doubt, take the car to your mechanic.
Frequently Asked Questions About the Fiat Sedici Gearbox
Which gearbox should I choose for a diesel Sedici?
The 1.9 diesel versions most commonly came with the six-speed manual gearbox, which is better suited to their torque. It is worth checking the exact reference for your vehicle, however.
Is the Sedici's automatic gearbox reliable?
The four-speed automatic gearbox, available from 2009, offers a comfortable driving experience. Like any transmission, it requires clean fluid and regular servicing to last.
Why is my Sedici losing power?
A loss of power may be caused by faulty gears or worn synchromesh rings. A diagnostic check will confirm the source of the problem before it gets any worse.
Repair or exchange: which should I choose?
When the cost of repair approaches or exceeds that of a replacement, a reconditioned gearbox on an exchange basis is generally the safer option.
