Hi, I have an 87 Accord, auto transmission, LX-i. When I slow down I hear a clunk from the rear end at about 15 mph. Once in a while, when I accelerate slowly, it clunks at about 25 mph. Had some work done on the car last month & mentioned this to the mechanic. He said the only think he could see was a loose pipe in the exhaust system, which he tightened. But the noise is still occurring. Any thoughts as to what it could be? (Transmission? I hope not!) I will probably take it to the dealership for a diagnosis but wanted to get some input before they tell me about the big $$$ they think it will take to fix it. Thanks! Sara
