I recently discovered that there was a chirping noise coming from my car. The gears are shifting fine with no sluggishness. I thought it was my belts but that wasn’t the case. The car was taken to a transmission shop by my local mechanic. They said it was the torque converter and it would have to be replaced and the transmission would have to be rebuilt because of metal pieces being passed on to the trans(repair cost $2,000 to 2,200). That was determined only by sitting on a rack with nothing else done. I went for a second opinion by taking it to another trans shop. He stated that the torque converter needs to be replaced but the trans does not need to be replaced(repair cost $500). He highly doubts that metal pieces were passed on because all the gears are shifting fine.
