I posted this a while back, but no posts on the subject. When ever I go into 5th gear I hear a buzzing noise behind me and to the left. I could be going the exact same speed in 4th gear and not hear it, but as soon as I go into 5th, I hear it. It gets a higher pitch the faster I go. Does anybody have any suggestions on the subject? The tranny was rebuilt a couple years back (two I think). Thanks for the help.

She loved sitting in the Delorean and watching me work on it. She was 14.
