Well, I put the car on stands and ran it on 4th and 5th from low to high rpm to look at the driveshaft and found the following. While 4th gear was not vibration free, it was fairly low and I think "acceptable", so while the bar starts to vibrate a bit towards 6000rpm, its not mayor. But in 5th gear it started vibrating almost immediatly (starting at like 2k rpm, so around 3k driveshaft rpm), and there was an additional "whomp whomp" noise that was rythmic with rpm. So apparently I have two problems, a driveshaft that cant go much higher than 6k rpm, and a transmission that has some kind of problem in 5th gear, apparently
