So I’ve recently purchased a 2000 v6 new edge. Got it for next to nothing knowing it needed trans work. Removed old transmission, the torque converter was locked in the transmission. Rebuild a trans and put a new torque converter. New fuel pump. And it had a misfire on one cylinder. Changed the plug and fixed that. But the car has a bad vibration that I can feel inside it pretty good, I’m hoping it isn’t something serious. Has any had problem like this and fixed it? I’m assuming maybe it’s a bad harmonic balancer but I’m not 100% sure. Any help would be greatly appreciated
