RV FEATURE
1 . TRANSMISSION FLUID COOLER
Automatic transmissions are more common than manual and can heat up a lot more than usual when towing a heavy trailer . While many modern autos run a transmission cooler , it ’ s often not enough . Many times the factory cooler is incorporated into the radiator assembly , and was never designed to keep transmission temperatures down when towing in our hot climate .
The most important upgrade for a tow vehicle is a seperate oil-to-air transmission cooler . Enquire with a transmission specialist , a transmission cooler supplier or even on a vehicle-specific forum to see what capacity will best suit your vehicle .
Transmission oil gets a work out and things could be improved with a transmission fluid cooler .
2 . ENGINE OIL COOLER
While we ’ re talking about extra oil coolers , some vehicles can improve their towing performance and longevity with an engine oil cooler . Some larger 4WDs already have an oil cooler factory-fitted , so you may not need one – or it might be improved with an aftermarket larger-capacity cooler .
Ask your vehicle ’ s manufacturer if they recommend an oil cooler or do actually factory-fit one as part of an optional towing package .
Otherwise , check out online forums for your vehicle ’ s make / model : you ’ d likely get good advice there if plenty of others also tow with your vehicle model .
