* Partial Fill (topping off): You'll likely only need a quart or less, depending on how low the fluid level is. Always check the dipstick after adding fluid.
* Complete Fill (after filter change or rebuild): This requires approximately 5-6 quarts. However, it's crucial to follow the specific instructions in your vehicle's repair manual or the instructions that came with your transmission parts. You may not need to add all of that at once. Some methods involve adding fluid and then running the engine to circulate the fluid and then checking the level again to add more.
Never overfill the transmission. Overfilling can cause serious damage. Always refer to your owner's manual or a reputable service manual for the exact amount and proper procedure for your specific vehicle and transmission.
