1999 Lexus RX 300 4 cyl Automatic 169090 miles

Hi, I have a 99 rx300 lexus and recently it looks like the o/d doesn't seem to be working. In the past I was able to drive up to 65 mph without going into 4th gear, but now it reaches 4th gear when I'm only going 45mph. Another thing that has just started to happen is that when driving, the car starts to slow down without me pressing on the brakes then returns to normal speed and back to slowing down again. thanks in advance.
