Additional Notes
- The Acura RDX TC1/TC2 2.0 i-VTEC automatic transaxle carries an overhaul capacity of 8.3 liters, which reflects the total fluid volume required when the transmission is fully disassembled and refilled from dry.
- The service fill capacity for the front-wheel-drive 2.0 i-VTEC is 4.3 liters, a figure that accounts only for the fluid drained during a routine pan-drop service, leaving residual fluid in the torque converter and passages.
- AWD variants of the 2.0 i-VTEC carry a wider overhaul capacity range of 7.8-8.8 liters, compared to the fixed 8.3-liter figure on front-wheel-drive models, indicating variability in total system volume across AWD configurations.
- The service fill range on AWD models spans 3.7-4.8 liters, a broader spread than the single 4.3-liter value on front-wheel-drive versions, reflecting differences in how much fluid is retained depending on the specific drain procedure or hardware involved.
- Both CAN and USA market front-wheel-drive 2.0 i-VTEC models share identical capacities across the 2018-2023 range, with no regional variation in either the 8.3-liter overhaul or 4.3-liter service fill figures.
- The same capacity parity between CAN and USA markets applies to AWD variants, where both regions share the 7.8-8.8 liter overhaul range and the 3.7-4.8 liter service fill range.
- All four configurations use a flexible service interval governed by the on-board maintenance system, meaning the transmission fluid change interval is not fixed at a set mileage or time period but is instead calculated by the vehicle's monitoring system based on operating conditions.
