Friend just had tranny rebuilt (last week) by reputable shop. Tranny is built by Mazda and a real booger to rebuild. My friend's friend is a transmission mechanic and recommended this other shop saying he wouldn't touch it as they are soooo difficult. Anyway, two new drive shafts were put in with this job. Car vibrates at 50 mph and above. Car was returned once but still vibrates. Sounds like a drive shaft problem to me but others here are much more knowledgable than me. WHAT COULD IT BE?
