Received an error message "Transmission Oil Temp gh" XC90

Customer Question

Received an error message "Transmission Oil Temp High" for 2005 XC90 V8. We are traveling north and have a bit of cargo. Can't figure out the code's meaning - is it due to driving 85 mph in high heat over a few hundred miles?

Hello, I'm Brandon.

That is correct. The transmission working too hard and the transmission fluid is overheating due to heavy load.

Expert:  internal88 replied 1 year ago.

When was the last time you did the transmission fluid change. If not, you should do one.

Expert:  internal88 replied 1 year ago.

This is the only way to protect the transmission from overheating.

Expert:  internal88 replied 1 year ago.

For now, you will need to cool down the vehicle and drive in cruising speed at 60 MPH.

Please rate me positive for the prompt service. Thank you!

Thanks for the help. I had been hoping for a quicker turnaround (not necessarily your fault) but the "wait time" was indicated at 30 minutes, and I waited quite a bit longer. Considering we were traveling, it would have been great to get some guidance sooner.
