My aod to T-5 swap has been finished for some time now and i just recently installed a new T-5 tranny because the first T-5 had some problems grinding gears. Well I installed the new T-5 this weekend and have been driving around without getting on it too much and i noticed that while driving above 3000 rpms, there is a bad vibration coming from the transmission. At first i thought it was the driveshaft, however when i pulled my car in the driveway and reved it in neutral, it vibrated once agian above 3000 rpm. However, when i rev it with the clutch pushed in, the vibration stops. I am starting to believe that there is a problem with the pressure plate which i installed a few months ago. Is it possible that i installed it wrong and it is causing this vibration? The problem isnt that bad right now because with the new tranny i shouldnt really be taking the car past 3000 rpms, however in one of these future weekends i'll probably have everything apart and i need some ideas on what to look for.
