well

RDJJ racing did my motor for me & we used hr mounts then I noticed a little vibration & thought that might have been it but then I started having trans probs especially with the new found power. The trans seemed to start vibrating more & more then took a dump. I got another brf trans built (thanks v6racer) & they are gonna put it in for me possibly this week & I will let you know if the vibration goes away. Good luck.

bad vibrations

with transmission in park.raise rpm to 2500 and vibration comes in.lower rpm and it goes away.when driving vibration comes in around 2500 rpm and goes away as speed and rpm increases gradually.I'm thinking it's the torque converter.still haven't had a chance to check under car yet.thanks for response.
