Vibrations in the sixth gear at 3200rpm
last year I installed in my 1993er turbo miata the drivetrain from a crashed anniversary NB.
Since that swap i got oszillating vibrations (depending to rpm) only in the sixth gear. They start at around 2400rpm, but there only very quiet. They get louder to 3200rpm-4100rpm where the reach there maximum. After 4100rpm they get very quiet or disappear completely.
Do you know that problem? In the german forum nobody knows that problem and could give me an advice.
I first thought that have to come from the cardan shaft, but if this would be damaged, it also has to vibrate in gear 1-5?!
I also checked and change the PPF-distance without a change.
Would be very nice, if you can help me.
Thanks so far!
