Gentlemen, I'm giving thought to trading in my signature vehicle for a newer truck. My F-150 has the 4.2 V-6/5 speed manual, 2WD driveline. It is a base model, XL trim, short box with 3.55 gears. It is in excellent condition with 76,000 miles and consistently gives me 19.3-20.5 mpg. The truck I am considering is a 2007 Silverado 1500 work truck. It has the 4.3 V-6/automatic 4 speed, 2WD, regular cab. Looks to be a very nice truck with 66,000 miles. I'm tired of shifting gears and would like an 8' box. I have no interest in a 4WD, super/quad cab truck. A 2 wheel drive suits me fine. My major concern is the reliability of the 4L60E transmission in this truck. I understand they have some issue's and an above average failure rate. What do you know about this. Please, lets not turn this into a Ford/Chevy debate. They are both good trucks. Incidentally, my F-150 has been an excellent truck with good fuel economy and low cost of ownership.
