Horrible Vibration
Horrible Vibration Once you reach about 60-65 mph the car starts to vibrate horribly... You don't feel it in the steering wheel or pedals... more in the seat, the console... You can tell it's coming from the transmission. It's a junkyard 4L80E w/ a Yank SS3600 converter, and for the life of me I can't remember what flexplate I went with... It wasn't cheap, that's what I remember lol...
Am I looking at converter issue? Flexplate? Or the fact that I'm running a complete bones tock transmission that already won't make the 2-3 shift under boost?

I know stock stalls dont like boost, big issues come from that, but since you dont have a stock stall I would think its coming from the transmission it self. If the tranny was already not getting 2-3gear than its a tranny problem. Have you tried a retune already?
