Hyundai Lantra/ Elantra, HD (EU)

Additional Notes

• The Hyundai Elantra HD automatic transaxle fluid capacity is 6.6 liters across all four engine variants covered in the 2006-2010 range, namely the 1.6 CRDi DPF, 1.6 CRDi, 1.6 CVVT, and 2.0. A figure in the 6-7 liter range is typical for a fully serviced automatic transaxle fill, which accounts for fluid held in the torque converter and valve body in addition to the main sump.
• Under normal use conditions, the automatic transaxle fluid check interval is set at 15,000 km or 12 months, whichever comes first. A periodic check interval shorter than the change interval is standard practice for monitoring fluid condition and level without committing to a full drain-and-fill cycle.
• The normal-use fluid change interval for all four engine variants is 90,000 km or 72 months. A 72-month ceiling means the fluid is replaced at six years regardless of whether the distance threshold has been reached, reflecting the time-based degradation of automatic transmission fluid independent of mileage accumulation.
• Under severe use conditions, the change interval for all four variants is reduced to 45,000 km, with no time-based interval listed alongside. Severe use classifications typically apply to operating conditions such as frequent towing, stop-and-go traffic, or extreme temperatures, all of which accelerate fluid thermal breakdown.
• The severe-use change interval of 45,000 km is exactly half the normal-use interval of 90,000 km across every engine variant in the 2006-2010 Elantra HD range. No check interval is specified under severe use conditions, only the change interval.
• No variation in automatic transaxle fluid capacity exists between the diesel variants (1.6 CRDi DPF and 1.6 CRDi) and the petrol variants (1.6 CVVT and 2.0), all of which share the same 6.6-liter figure. This uniformity suggests a common automatic transaxle unit was fitted across the HD generation regardless of engine type.
