Default High Trans Fluid Temp

I am getting a service engine message that goes off when I am driving for 45 minutes or more at highway speeds. Immediately when I slow down on a ramp, the light goes off and doesn't come back on until I am driving again for 45 minutes or more at highway speeds.

When I took it to the dealer, he wanted to change the oil control valve for $900.00 and said that might fix something.

Has anyone had this message? Any suggestions?

you must be out of warranty. Get a second opinion from another Lexus or Toyota dealer or a qualified independent mechanic. There should be stored codes they can download. This should not involve guessing.
