Proton S70 DCT Fluid Malaysia
S70 7-speed wet DCT: fluid every 40,000 km. Use Geely/Proton-specified DCT fluid only. Sedan: less torque load than X70 SUV. Software update at Proton SC before DCT fluid change: reduces shudder risk.
- 7-speed wet DCT (Geely/Getrag): Geely-specified DCT fluid only; every 40,000 km; RM 280–420
- Do NOT use generic ATF — wrong fluid causes DCT clutch pack damage
Proton Gearbox Fluid — Malaysia Guide
Proton models use different transmissions: Saga/Persona use a 4-speed auto (Dexron III ATF) or 5-speed manual; X50/X70/X90 use a 7-speed dry dual-clutch (7DCT) requiring Geely-spec DCT fluid — NOT standard ATF. The 7DCT is sensitive to fluid degradation; change every 40,000–60,000 km. Clutch adaptation reset is sometimes needed after fluid change — only a Proton-equipped scanner (PTSS) can do this properly.
