HI,
I have a 2013 1500 Silverado Z71 with a 5.3 engine and 3.42 gears and I'm thinking of adding a another transmission cooler.
I pull a camper in the summer. Any input on what cooler kit I should get

 

Completely unnecessary. But if it makes you feel better, go for it.

 

Don't need to add another cooler, but a bigger one sure wouldn't hurt. Look into the tru-cool 40k

 

my transmission course instructor from dealer training used to say.....if your trans is running to hot with the existing cooler....you bought to small of truck. adding coolers is a band-aid...it the trans is producing that much heat your working it to hard.

same for the people who overload there 1500 and then add air springs.
