Lexus NX 200t/300 6AT ATF Service & NX 300h eCVT Malaysia
NX 200t/300: 6AT (AB60F) using Toyota WS fluid. Drain/fill 3.7L every 20,000 km. Turbo models benefit from the shorter 20,000 km interval. NX 300h: eCVT Toyota CVTF WS, drain/fill every 20,000 km. Both cost at a specialist. Neglecting ATF leads to delayed upshifts on the NX 200t/300 and jerky acceleration on the NX 300h.
Lexus NX Gearbox / Transmission Service
- NX 200t/300 (8AR-FTS): 6-speed automatic (AB60F) — Toyota WS ATF; change every 20,000 km — do not trust 'sealed for life' claim
- NX 300h: eCVT + rear MG motor (E-Four) — no conventional ATF change; rear electric motor has own cooling loop — inspect at 20,000 km
- NX gear hunting: if NX automatic hesitates or hunts between 2nd and 3rd gear — likely ATF degradation; change ATF first
- Only use Toyota WS ATF on NX: incorrect fluid causes shudder and premature clutch wear — not negotiable
