Parts for your 2010 Ford Fiesta-Transmission fluid

2010 Ford Fiesta transmission fluid — what it does and when to service it

Transmission fluid absolutely is relevant to a 2010 Ford Fiesta. Technical sources including the 2010 Ford Fiesta Owner’s Guide and Ford Workshop Manual specify dedicated oils for every gearbox fitted to this model. The 4‑speed automatic (4F27E) uses an automatic transmission fluid to MERCON V specification, while the 5‑speed manual (IB5/IB5+) and the later 6‑speed Powershift (DPS6, dry‑clutch) use dedicated manual/DCT transaxle fluid meeting Ford’s WSS‑M2C200‑D2 (or its latest supersession). Getrag/Ford service literature for DPS6 notes it’s a dry‑clutch unit, so it doesn’t use a traditional ATF for the clutches, but it still relies on the correct gear oil inside the transmission case.

For a Fiesta of this era, transmission fluid is doing the heavy lifting: it lubricates gears and bearings, cools components, reduces wear, and (in automatics) provides the hydraulic medium for smooth shifts. Fresh, correct‑spec fluid helps the box shift cleanly, keeps noise down, and extends service life — a small outlay compared with a gearbox rebuild.

Servicing advice for Aussie and Kiwi owners is simple: match the fluid to the gearbox. For the 4‑speed auto, use MERCON V ATF only. For the 5‑speed manual or DPS6, use the Ford‑approved manual/DCT transaxle fluid to WSS‑M2C200‑D2 (check your handbook or dealer for the latest part number). Avoid mixing types.

Intervals vary by use and transmission. While some guides list these as “filled for life”, Ford service information and industry practice in our conditions make a strong case for periodic changes:

• 4‑speed auto (ATF): inspect condition annually, change around 60,000–80,000 km if you do a lot of city, hot‑weather, towing, or hilly driving.
• 5‑speed manual/DPS6 gear oil: inspect for leaks and level annually, refresh around 100,000–150,000 km, or sooner if shifts feel notchy or there’s bearing whine.

Tell‑tales that it’s time include harsh or delayed shifts (auto), graunching or notchiness (manual/DPS6), fluid that’s dark or smells burnt, or weeps at driveshaft/selector seals. When servicing, use new sealing washers, set the level exactly as per Ford’s procedure (temperature matters on automatics), and don’t overtighten plugs. A reputable workshop will also road‑test and check for software updates on autos and DPS6 modules.

These recommendations align with Ford’s owner and workshop publications for the 2010 Fiesta and the known characteristics of the 4F27E automatic, IB5 manual, and Getrag DPS6 units used in this model range.

Popular questions

What transmission fluid does a 2010 Ford Fiesta take?
It depends on the gearbox. The 4‑speed automatic uses MERCON V ATF. The 5‑speed manual and the 6‑speed Powershift (DPS6, dry‑clutch) use a dedicated manual/DCT transaxle fluid that meets Ford WSS‑M2C200‑D2 (or its latest supersession). Always confirm the exact spec in the owner’s handbook or with a Ford dealer using your VIN.

How often should the transmission fluid be changed on a 2010 Fiesta?
There’s often no strict interval listed, but in Australian and New Zealand conditions many workshops recommend about 60,000–80,000 km for the 4‑speed auto ATF and 100,000–150,000 km for the manual/DPS6 gear oil. If you drive mostly in heavy traffic, hot climates, tow, or notice shift quality dropping, service earlier.

Are Powershift (DPS6) clutches “wet” and do they use ATF?
No. The Fiesta’s DPS6 is a dry‑clutch dual‑clutch unit. The clutches aren’t bathed in oil, so there’s no ATF for the clutch pack. However, the gearbox still uses a specific transaxle fluid for the gears and bearings, and it must meet Ford’s specified standard.
