I've got a 99 5.3 Silverado Z71. I do some towing in the wintertime.(snowmobiles) Does anyone have or recomend installing a trans cooler or oil cooler? Any great advantanges? Besides cooler temps?

 

A tranny cooler won't hurt. If your towing snowmobiles in the winter I wouldn't even bother. But that's me. I tow a 30' travel trailer in Texas heat w/o a cooler with no problems. My temp still never gets over 190. But hell for 60 bucks why not put one on. That's what I keep telling myself. I may do it this weekend.
