I just put a Full racing b$m th350 in my 89 rallysport. it has all the goodies, only thing is when it shifts from 1-2 doing 4000+ rpm it sound like a wild freikin bear is hitting the botom of my car right below the console. my question is is there a rubber spacer in between the tranny and the bottom of the car where it mounts up to hold it down(looks like something should be there, theres little clips) also, only about 1/2 inch of my torque arm is in the mount(th350s are two and a half inches shorter)could that be doing it? Also is there another mount, i have a torque arm, the cat mount and that it except for the cross member, seems like ther should be more, or is it the fact that the mounting system in my rallysport isnt meant to hold up to the hard shifts i get out of the tranny(can burn the tires going from 2-3) as always and help or suggestions are appreciated, Thanks!
