Thanks for the tips. Apparently I was using the wrong search terms, because I couldn't find that thread. Anyway, a change from 3.69 to 3.46 doesn't sound worth the effort.

These things really buzz at 70mph, and I hear of others that steady state cruise at 80. Isn't that near redline? You all really drive that fast all the time? The cruise still works on my car, so I thought of just setting at 70 and forgetting about it, but am having trouble with that last part.
