I checked the tranny fluid level today and there were bubbles on the dip stick. I don't remember seeing this before. The oil level wasn't too high. Should I be worried? My truck is a '97 4.6L with 60,000 miles on it.

 

Some bubbles in your fluid is no big deal. As long as the fluid is at the correct level, it smells "fresh", and has good color you are in good shape.
