I will likely be selling my Jeep this Spring to get a 99+ Silverado or Sierra. Are there any common problems to look out for? I have heard that the 5.3 is a great motor, however I am uneasy about the 4L60E. I have been warned by a few people that it is not a great transmission. The truck would be used primarily as a daily driver, and occasional tow rig for the Talon on track days. How does everyone seem to like these trucks? How is fuel mileage on them? I have heard everything from 16-24MPG.
