Transmission, clutch & driveline
Automatic transmission fluid change
The service the phrase "lifetime fill" talks people out of. The work is mostly patience and cleanliness; the parts that are not are per transmission: fluid spec, fill procedure, and the level check, which on many modern units needs a scan tool and a temperature window.

Vehicle-specific notes
Where verified data exists for this job, and how far each row is verified. The values themselves (capacities, torque) live in the product, attached to an exact vehicle: an unsourced value never gets printed, and this page prints no values at all.
- Porsche · Cayenne · 958 / 9Y0Community-verified — confirm for your VIN
- Ford · Focus / Fiesta · 2011 to 2016Community-verified — confirm for your VIN
Most 2011-2016 Focus/Fiesta automatics ARE the DPS6 "PowerShift" dry dual-clutch, not a torque-converter box.
If this car shudders at low speed: that is the DPS6 dry dual-clutch, and no fluid change addresses it, because the clutches run dry. Check the VIN's extended-coverage/settlement status before paying for transmission work; the PowerShift has its own service path.
- Nissan / Infiniti · CVT / XTRONIC / RE0FCommunity-verified — confirm for your VIN
Nissan/Jatco RE0F-family CVT — Altima, Sentra, Versa, Rogue, Pathfinder, Murano, Maxima and Infiniti equivalents, roughly 2013-2018 for the judder-era units.
The widely reported failure pattern on the 2013-2018-era units is judder/shudder under light throttle around 30-45 mph, with premature failures behind it.
Multiple DISTINCT class actions and warranty extensions exist across different model populations with different terms — do not assume one settlement's coverage applies to another model. If a judder complaint comes up, check the specific model/year's extended-coverage status before paying for a unit.
Independent specialists broadly advise against treating the fluid as lifetime — regular drain-and-fills are the cheapest thing an owner can do for one of these.
- Subaru · CVT / LINEARTRONICCommunity-verified — confirm for your VIN
Lineartronic-equipped Subarus only. Manual WRX/STI and the BRZ (manual or conventional torque-converter auto) are not CVT cars.
The trap: the US normal-duty schedule lists NO fluid interval, which owners read as "lifetime". The severe-duty schedule DOES list one, and dealers and independents alike commonly advise a proactive change around 30,000-60,000 miles.
Early Lineartronic units (2010-2014-era Legacy/Outback, spreading to other nameplates later) showed chain/pulley wear as fluid degraded — whine and slip under load — and Subaru extended CVT coverage on a range of model years rather than recalling. Check the VIN's coverage before paying for a unit; a confirmed internal failure is dealer/transmission-shop territory, not DIY.
- Mercedes-Benz · 722.6 / 722.9 / 7G / 5GCommunity-verified — confirm for your VIN
"Lifetime fill" was the factory position; independent specialists broadly advise 40,000-60,000-mile fluid service for cars kept long-term or driven hard, and Mercedes itself later issued shorter intervals on some applications.
Checking cold, or hot without measuring, gives a false level — overfilling risks aeration, underfilling starves the clutches.
