Possible reasons: Bad water pump, Bad temp sensor, bad fan motor of fan belts or fan clutch, No thermostat or stuck, cooling hoses weak and collapse (bottom), catalytic converter clogged, Late timing, Plugged radiator, Low oil level, Bad radiator cap, Coolant lever low, Head Gasket Blown, Transmission (lines run into radiator, may need an external cooler), Dirty/Greasy engine, Bad oil, Towing, Engine needs tune up, Bent exhaust, Air filter dirty.

Towing puts extra strain on the engine and transmission, need I say more. If so your engine & trans makes more heat, the fluids break down faster, end result is higher temps. If your cooling systems are not up to par for the many reasons, then you overheat, when the engine & radiator is above normal operating temps your trans is too and vise-versa if cooling system is not working proberly because the trans cooling is integrating into the radiator. May need fluid changes sooner too. Be sure your radiator fans are working & clean (Not clogged with mud). Look for bad hoses that are not holding their shape, air in cooling system may need bleed out, radiator or over-flow caps may not be holding pressure, exhaust clogged with mud, Radiator fins (metal fins between the radiator's passageways) clogged with mud, Head gasket blown, there are some reasons, If fans are not working check connection to temp sensor & sender & to fans & test fan relay(s) .

Determine if the radiator fan is functioning. Test for head gasket failure using a exhaust in coolant test/block test and compression test either or both ways to do so by turning motor over with gauge attached or using air compressor to hear air escaping.
