How many liters of transmission fluid does the Reiz 2.5 require?

The Reiz 2.5 requires approximately 12 liters of transmission fluid if using a circulation machine for replacement, while manual replacement typically needs around 5 liters, as manual replacement can only replace about 40% of the old transmission fluid. Below are some relevant details: 1. Transmission fluid is a lubricant that maintains the cleanliness of the gear system, extends the lifespan of the transmission components, and provides effective lubrication even in low-temperature conditions, reducing fluid loss under harsh operating conditions. 2. Automatic transmission fluid is generally recommended to be replaced every 40,000 kilometers, but owners can decide whether to replace it based on their actual driving conditions. If gear shifting is smooth and there is no significant change in transmission noise, replacement may not be necessary. 3. If you feel noticeable stiffness or jerking when shifting gears, especially when driving over 100 km/h, and the transmission noise increases significantly, it may be time to consider replacing the transmission fluid. Additionally, it is important to regularly check the automatic transmission fluid level to ensure it is within the normal range.
I just had the transmission fluid changed on my Reiz 2.5 last year, and I specifically asked the master technician at the dealership. He said for a gravity drain, you'll need 6 to 8 liters, and doing it in two stages gets it cleaner: first drain and add 4 liters, drive a few hundred kilometers, then do another 4-liter change. If you opt for a flush machine to do it all at once, it takes a full 12 liters. I went with the two-stage gravity method for convenience, and it cost me nearly a thousand yuan including labor. A quick tip: stick with the original Toyota WS fluid for the best match—using other brands can cause jerky shifts. For older cars, it's better to change every 50,000 kilometers to keep the transmission in good shape.
Last time I helped a friend change the transmission fluid for his Reiz, I did thorough research. The method matters for this car: a standard gravity drain uses 4-5 liters but only replaces half the old fluid. For a complete change, you'd need to do it twice, totaling about 8 liters. A machine flush requires 10-12 liters per change - more expensive but much cleaner. I recommend direct machine flushing for vehicles over 6 years old, especially highway cruisers. Never use the wrong fluid - Toyota WS-standard ATF is the safest bet. After changing, have the mechanic check the dipstick - the cold fluid level should be exactly at the midpoint.
My Toyota Mark X 2.5 had its transmission fluid changed at 80,000 kilometers. The repair shop said this car's oil pan has a special design - a gravity drain requires removing the oil pan to clean the filter screen, needing 7 liters including cleaner and new fluid. A machine flush would consume even more, requiring at least 12 liters. I opted for three 4-liter cans of genuine Japanese OEM fluid in steel drums, which was just enough. After the change, gear shifts feel noticeably smoother. I recommend not exceeding 60,000 km between changes. DIY is quite challenging as the oil pan gasket is prone to misalignment causing leaks - best leave this professional job to the experts.
