GOH10 Runner said:04 and up T4R's have a "sealed" transmission, meaning there is no dipstick to check. They also say that the fluid is lifetime but you can still get the fluid drained and filled but I personally would recommend staying away from flushing the fluid, it can cause a lot of problems. I try to get mine drained and filled about every 30k.
