2010 Rx350 Transmission Fluid High Temp

[ahh01010]

Hey guys,

I have a 2010 RX 350, about 10k miles. I was driving to vegas from LA several weeks ago, and after 2.5 hours of non stop driving, the warning light was on with the message "transmission fluid high temp".

It happened twice on separate occasion to vegas. I took it to the dealer and they said they cannot find the problem from the computer error code.

Can anyone help?

take it to lexus and ask them, an additional transmission fluid cooler may help
