Mark,

4,000 lbs isn't much weight and chances are, you'll probably be just fine.

However, I can tell you that I used to overhaul GM's automatic transmissions for a living and I wouldn't even tow a row boat with that outfit without first having the external GM transmission cooler mounted out front.

That transmission just cannot stand the heat. GM's "Tow Package" is nothing more than a wiring loom from the fire wall to the back bumper and does absolutely nothing to improve the cooling.

In addition, GM tells you not to tow in overdrive. Okay fine. But in fact, this actually adds to the problem because of the extra heat generated in that torque converter.

From the factory, they just simply are not engineered to tow. Put the external cooler on and at least you have a fighting chance.

Just trying to help,

Allan
