well three months ago i got my oil changed and mankato honda said i needed new shift bushings. i bought some but never put em on. this past friday i got my civic back from the auto body shop from hitting a deer. when i was driving around i heard a horable rattle sound so i poped my hood and noticed my heat sheild was rusted off the manifold so i took it off and the rattle went down. i brought my car to a friends shop and he looked at it. he noticed on my exhaust that i had midas put on didnt not have the felx thing after the down pipe. he thought maybe from the torqe the exhaust was rattling on something. so yesterday i taked to midas and they said they would fix it for free. i went home and put my header on then drove it to midas and they put it on right thing on. while i was drving away in second gear when i let off the gas it pops out of gear and still rattles when driving in gear out of gear it doesn;t rattle. my question is could this be due to the fact i need new bushings for my shifter?
