I don't know if this has been going on for awhile or it just started. Maybe it was there from the beginning of the install. Upon heavy acceleration I've noticed that my steeda shifter vibrates quite a bit. It, of course, is a lot louder at higher rpm's. I've checked the two bolts for the handle and they are tight. I've been too lazy to check the four bolts that attach to the tranny!:rollseyes I can hold the handle tight and the vibration will be minimal. Tell me if I]m just being paranoid cause I'm thinking that vibration has been there all along.
