My 86 Chevy Monte Carlo L s does the rattling while driving at thirty five miles in hour, I have to hit the gas in order for it to go away. But when I slow down and the transmission kicks down to second my car jerks and the rattle get loud until it's picks up speed.
Can someone help fix this problem let me know what the problem with that
