Actually, it was pretty much all regarding the 3.9 and 3.5L engine, which isn't relevant here. In fact, your thread title and question had nothing to do with the car as a whole, rather the question was aimed at the 3.9L engine specifically. What was said regarding the car as a whole in your thread still holds true as to what's been echoed in this thread, mainly regarding the transmission- the 4T65E can be the weak link when neglected, but can also be pretty stout with regular maintenance.
