Bought a 2011 Sequoia 5.7 and had the TRD Supercharger installed. Took a trip pulling my Haulmark Transport 7 x 14 v-nose cargo trailer. Running above 60 mph on freeway in Tow/Haul mode transmission gets hot. Will run 20 to 50 miles OK then temp starts to climb. I need to "feather" the RPM's down below 2000 to get temp to drop back to normal. Very aggravating and made for a long 400 miles. Dealer could not find a problem, says I need to put automatic transmission into manual mode when hauling this trailer. Seems odd. Trailer loaded was less than 3,000 lbs. Truck pulls it easy. Can anyone help?
