The Infiniti Q50’s 7-speed automatic transmission typically holds about 11 to 12 quarts of fluid when filled to specification. A simple pan drain and refill usually requires about 4 to 5 quarts. Exact numbers can vary slightly by model year and configuration.
Understanding the Q50 transmission capacity
The Q50 uses a 7-speed automatic transmission. The capacity depends on whether you are performing a basic pan drain and refill or a full service that includes replacing the filter and draining the torque converter, and it can vary by year and market. The figures below reflect typical ranges for common service scenarios on the 7-speed automatic used in most Q50 models.
Before you review the figures, note that these numbers are approximate ranges intended to guide maintenance planning. For exact specifications, consult your owner's manual or a certified Infiniti technician.
- Total system capacity (including torque converter and cooler lines): 11.0–12.0 quarts
- Pan capacity (fluid held in the oil pan only, excluding the torque converter): 4.0–5.0 quarts
- Drain-and-fill service amount (pan drop, no full service): typically 4–5 quarts replaced with fresh fluid
- Full transmission service (drain, filter replacement, and refill to spec): about 11–12 quarts
Concluding note: If you’re planning a transmission service, expect to replace roughly 4–5 quarts for a simple drain-and-fill, and budget around 11–12 quarts for a full service. Always verify with your vehicle’s manual or a qualified technician, as capacities can vary slightly by model year and engine configuration.
Summary
In brief: the Q50’s 7-speed automatic generally requires about 11–12 quarts of transmission fluid for a full service, with a typical pan drain-and-fill needing about 4–5 quarts. Use the official manual for your exact year and configuration to ensure precise filling levels.
