Fluid type explained
The 2018 Toyota RAV4 uses a specific type of transmission fluid called Toyota Genuine ATF WS (World Standard). This is a synthetic fluid with a lower viscosity than traditional ATF, which helps to improve fuel economy and transmission performance. It is important to use only this type of fluid, as using a different type can damage the transmission.
Service procedure
There are two main ways to service the transmission fluid in a 2018 Toyota RAV4: a drain and fill, or a full fluid exchange.
A drain and fill is the more common method, and it is the one that is recommended by Toyota. This procedure involves draining the old fluid from the transmission pan, and then refilling it with new fluid. A drain and fill will typically replace about half of the old fluid.
A full fluid exchange is a more thorough procedure that replaces all of the old fluid in the transmission. This is typically done using a machine that connects to the transmission cooler lines. A full fluid exchange is not always necessary, but it may be recommended if the transmission has been subjected to severe use.
Service interval
Toyota recommends that the transmission fluid be inspected every 30,000 miles, and replaced every 60,000 miles for vehicles operated under severe driving conditions. For vehicles operated under normal driving conditions, the transmission fluid is considered a "lifetime" fluid and does not need to be replaced. However, many technicians recommend replacing the fluid every 100,000 miles, regardless of driving conditions.
Common transmission problems
The most common transmission problem with the 2018 Toyota RAV4 is a shudder or vibration that occurs when the transmission is shifting gears. This is often caused by a software issue, and can be fixed by updating the transmission control module (TCM) software. Other common problems include delayed engagement, slipping, and harsh shifts. If you are experiencing any of these problems, it is important to have your vehicle inspected by a qualified technician as soon as possible.
