after installing my steeda transmission bushing the thud has almost but all gone away. Been trying to listen for it but haven't really heard anything. The thud that i use to get from stopping at a light and going back to first or seconds seems to have gone away too.
Installed mine today and I'm not sure if it's a placebo effect or not but it definitely feels smoother when going through the gears. I also haven't noticed any added NVH after install.
