How much transmission fluid do I need in litres?
Automatic transmissions typically require about 6–14 litres to fill to capacity, while manual transmissions usually need about 2–4 litres. The exact amount depends on your vehicle model and whether you’re performing a full replacement or a simple drain-and-fill. Always check your owner's manual for the precise figure.
Understanding transmission fluid capacity
Transmission fluid capacity is the total amount the transmission can hold when it is completely full. The amount you actually replace during service depends on the procedure: a pan drain and refill typically removes only part of the total capacity, whereas a full flush or complete refill aims to replace the entire contents.
What affects the capacity numbers?
Several factors influence the published capacity, including the transmission design (automatic, manual, CVT, or dual-clutch), the number of gears, whether the unit includes a cooler loop, and if the vehicle uses all-wheel drive. Always verify with official data for your exact model.
Typical capacity ranges in litres
These ranges give you a baseline for planning maintenance. For accuracy, consult the owner's manual or service data for your specific make and model.
- Automatic transmissions (compact cars): approximately 5.5–9 litres
- Automatic transmissions (mid-size sedans and crossovers): approximately 7–11 litres
- Automatic transmissions (full-size sedans, SUVs, light trucks): approximately 9–14 litres
- Manual transmissions (compact cars): approximately 2–3.5 litres
- Manual transmissions (larger vehicles or AWD): approximately 3–4 litres
Note: These figures are rough guidelines. The exact capacity for your vehicle will be listed in the official documentation or by a dealer service department. Do not rely on these ranges as a substitute for your car’s precise specification.
Finding the exact capacity for your vehicle
To accurately determine how much transmission fluid your car requires, use these steps.
- Consult the owner's manual or the manufacturer's service data for total fill capacity in litres.
- If you don’t have the manual, use the vehicle’s VIN on the manufacturer’s website or a trusted service portal to pull the exact specification.
- Contact a dealer or qualified mechanic with your VIN to obtain the precise figure for your transmission variant.
- Understand whether you are performing a full flush/total replacement or a drain-and-fill, so you apply the correct amount.
- When performing a drain-and-fill, plan to replace a portion of the capacity (commonly around 3–6 quarts / 2.8–5.7 litres for many automatics) depending on the drain method.
With the exact specification in hand, perform the service following proper procedures to avoid under- or overfilling, which can cause shifting issues or damage.
Summary
Transmission fluid capacity varies by vehicle and transmission type. Automatic transmissions typically require about 6–14 litres to reach full capacity, while manual transmissions usually need 2–4 litres. Always check the owner’s manual or dealer data for your exact model, and distinguish between total capacity and the amount you replace during service. When in doubt, consult a qualified mechanic.
