If your Sorento's gearbox has been behaving oddly lately – unusual noises, gears that are hard to engage or jump out whilst driving, or oil patches under the SUV – replacing it isn't always the answer. Depending on the situation, a few adjustments or an oil change may be all that's needed, though a serious fault can sometimes make replacement unavoidable. Here is everything you need to know to deal effectively with the gearbox on your Kia.
What type of gearbox does your Sorento have?
Ordering the right gearbox is impossible without knowing the reference of the unit to be replaced, as the Sorento's drivetrain has changed considerably over the years:
- in 2002, the 2.4L 139 hp and 3.5L V6 195 hp petrol engines came with a 5-speed manual or a 4-speed automatic, while the 2.5L CRDi 140 hp diesel was supplied with a 5-speed manual;
- from 2006, the diesel was uprated to 170 hp and the optional automatic gained a fifth ratio;
- from 2009, 6-speed manual and automatic gearboxes appeared;
- in 2017, an 8-speed automatic was fitted to the 2.0L T-GDI 240 hp petrol;
- the 1.6 T-GDi hybrid and plug-in hybrid variants (230 and 265 hp) share a 6-speed automatic, while the 2.2L 202 hp diesel retains the 8-speed gearbox.
The V5C logbook, a label, or an engraving on the casing will help you identify the correct reference. If in doubt, seek advice from a professional. To help you choose between gearbox types, our guide on manual and automatic gearboxes is a good starting point.
Should you take it to a mechanic?
Without hesitation, yes: automotive mechanics are more complex than they appear, and depending on the gearbox type, electronic components are involved. A rattling noise, crunching, stiff gear engagement, or a burning smell should prompt you to book a diagnostic. What seems like a minor fault can quickly develop into more serious damage and compromise your safety.
After the diagnostic, the professional will provide a quote detailing the work required: securing components, an oil change, replacing worn parts, or a complete exchange of the gearbox. In the latter case, you are under no obligation to let them source the gearbox – ordering it yourself is often more cost-effective.
How do you get the right gearbox at the right price?
At EDEN BOITES, we focus on first-quality gearboxes. For occasional use, a rigorously tested used unit is an economical option. For an everyday vehicle or long journeys, an exchange gearbox offers lasting reliability. And if your reference is not in our catalogue, reconditioning your own gearbox remains possible: drained and removed by your mechanic, it is rebuilt in our workshops to its original specifications.
Two convenient delivery options
Because a gearbox is heavy and bulky, its delivery is worth thinking through. The first option is to have it delivered to your home address, which is practical if you have a suitable means of transport to take it to the garage afterwards. The second option, often more convenient, is to give your mechanic's address directly, so they can fit it and carry out the necessary checks as soon as it arrives. This second option saves valuable time and spares you any awkward handling. Whether you are based in France or elsewhere in the European Union, simply specify the delivery address when placing your order.

Frequently asked questions
Where can I find the reference for my Sorento's gearbox?
On the V5C logbook, or on a label or engraving on the casing. If the marking is illegible, a professional will confirm the correct reference to order.
Is it better to have the gearbox delivered to my home or to the garage?
A gearbox is heavy and cumbersome. Having it delivered directly to the workshop avoids awkward handling and saves time.
How can I avoid a repeat fault after repair?
Drive responsibly, follow the service schedule, and use a compatible lubricant when changing the oil.
