In some vehicles, the automatic transmissions over heat light may come with sustained highway driving or driving at a sustained speed. Our technicians tell us that flushing the transmission and changing from Dextron lll to Dextron ll can help remedy this problem.

    1993 4runner 108560 miles, on Phoneix to LA run, overheats on grades 105 degree heat with AC on. When the trans hot idiot light comes on, I turn off the AC, slow to to 50-60 (whatever the truck holds easily in high or no overdrive, and the light goes off in about 15 minutes. Poor thing has no power to hold grades without working its little butt off, which the coolant temp and oil temp have no issue with, but the trans sure does.
