I've been getting A/T temp lights. 1st time was shortly after my timing belt was done. I pulled over & found the Rad reservoir was empty. Let it idle as manual says to do for temp lite, added coolant & waited for light to go out. Continued on to an off-road trip and no issues. Few weeks later similar trip no lite until late in the trip, then went on a couple more times after cooling. Took it in asked shop change drive train fluids & to look at it. Don't think they looked at it but did change the fluids. Drove it around town no issues a just went on a trip & it overheated again. I can't feel fluid flowing in the rubber lines leading to or from A/T cooler. Also the lines don't feel hot after driving. What temp does the light go off at? What could cause the fluid not to flow through the cooler. In a 12 mi city drive the temp can get to 240 (no A/T light). I just started monitoring A/T temp so not sure what temp it is when light goes on. I did pop one of the A/T cooler lines off, there was fluid in it didn't gush out.
