With a new job in Fort Myers and a dependent family in Jacksonville, I've been driving my car 7 hours each way, taking the side roads. (I'd get angry motorists on the Interstate; best and most gas efficient speed is 50mph.) So, I'm using my car on long highway trips, and clearly my car is not a highway machine, especially since I don't have overdrive. In the last ten miles of the most recent Christmas journey, I started hearing strange noises in third gear.
The car has needed tuning for a while and a good lube job. I've got it on stands and am finding all the nibs with the help of my owner's manual.
