Lexus ES 250/300h ATF & eCVT Fluid Malaysia — 6AT Must Be Flushed at 60,000 km
ES 250 (6AT): Toyota Genuine ATF WS or approved equivalent. Capacity: 7.4L (full drain) or 4.0L (pan drop). Change interval: every 60,000 km — ATF WS is a lifetime fluid in Toyota spec theory, but in Malaysia heat this is not practical; neglected ATF turns dark and causes shift hesitation or torque converter shudder from 80,000 km. Method: full flush at specialist (RM 500–800) using flushing machine, not just pan drop. ES 300h (eCVT): no ATF in the traditional sense — the power split device uses Toyota Genuine CVT fluid, 4.0L capacity, change every 80,000 km. Warning: never use non-Toyota ATF WS or generic CVT fluid in the ES — the tolerances in both the 6AT and eCVT are too tight for off-spec fluid. Signs of ATF issue: delayed engagement when shifting from P to D, rough 1-2 gear change, and in severe cases transmission fault codes on Techstream.
