6.0 Tow/Haul Flashing and Check Guages On
I have a 2004 350 6.0. While pulling a 4 ton load using Tow/Haul mode and cruise control (maybe shouldn't do that??) the "check gauges" came on along with the Tow/Haul light started flashing. When these lights come on the Trans. Temp. Gauge goes down to cold. I had the codes read by a local shop that has a reader for Ford Specific codes and I got codes for cruise control and A/C problems. My cruise and A/C are working fine. Based on other things I've read, I was expecting a code for trans. Temp sensor. Now I don't know what to think.
The Truck is running and shifting fine, even while towing. The guy tried to clear the codes but the lights came back. Transmission has been serviced with appropriate fluids. Any guidance would be great. I can't afford the Ford Service right now and want to fix this myself if it isn't over my head.
Thanks for any info.
