I did a quick search on the Forum and couldn't find any information on this topic. I have a 99 with 102K miles. Bought it used 2 years ago. Anyway, it does between 2,000 and 2,100 rpm at 60 mph. Then at 70 mph, it's doing close to 2,500 prm. Is this typical? Seems high to me, considering the V-8 and everything. I know the 03 and newer have the 5-speed trans, which probably drops down the rpm at highway speed. Thanks for your help.
