My 2004 Lexus LS 430 has had the light come on several times, even after changing all four tires. There are no tire pressure sensors on my four tires. I was told the car computes tire rotations and since a low pressure tire takes more rotations than a fully inflated tire, the computer puts up a message on the dash.
To reset/turn off the message, put the emergency brake on, start the car and reach below the dash to the right side of your steering column until you feel two buttons in a depressed area under the dash. One button turns on /off your smart key and the other will turn off your tire low pressure message. Depress and hold until the message on your dash goes out and you are good to go. I know this works, I just reset mine a few minutes ago.

most modern vehicles no longer have dipstics, but there is a fill plug, i do not know where it might be but look for a plug with a allen wrench hole on the tpo or upper side of the trans, with the plug removed add fluid untill you can see it thruogh the hole (if on top) or if it is on the side add untill it just starts to seep out at the bottom edge of the plug hole
