Engine & Trans Temps While Towing
This weekend when hauling my travel trailer (approx 4500 lbs), I noticed that the engine and trans temp was climbing higher than usual. I went most of the way on relatively flat ground between 55 to 60 MPH with very little stopping and accelerating. The outside temp was probably 95 degrees. The engine temp at the highest was reading right between the "A" and the "L" in (normAL), but normally stayed between the "M" and the "A" (norMAl). The trans temp at the highest was around 230 degrees, but usually stayed 210-220. On hot days like that, my engine temp usually stays below the "M" and the trans ranges between 180-195 when not towing.
Should these towing temp ranges be of any concern? The truck didn't exhibit any problematic signs while underway. Granted, this was the hottest day I've towed anything heavy, but I've just never seen the temps go that high.
