So I posted another thread about this a while back, no replies, reread it and I rambled alot lol. So I'll get to the facts. I have a strong pulsating vibration at high rpm, in gear only, and it's not speed related....I'm thinking it's the trans. Reason is in neutral I can Rev it up really high, no vibration, I can go 130 in 6th gear and never feel it, but if I'm Rollin in 1st and punch it I feel it at the top of every gear. Anyone else experiencin this? I'm going to regap the plugs as maybe it's an ignition issue that only occurs when the engines under load? I'm not sure

Give me some ideas guys!

Some sort of harmonics issue is my guess.
