Mercedes-Benz GLA — 变速箱油
Same as CLA: identify gearbox type before selecting fluid. X156 GLA pre-2016 may have 7G-Tronic (MB 236.6 ATF). X156 GLA post-2016 and all H247 GLA use 7DCT (DCT-specific fluid, NOT ATF). Never use 9G-Tronic ATF (MB 236.15) in 7DCT.
Service Intervals
- 7DCT: every 40,000–60,000 km; 7G-Tronic: every 40,000 km
- Earlier if judder appears or fluid smells burnt
