I have a 2004 Acura MDX with about 115K miles on it. I recently heard a slight grinding sound as the car accelerated, and I took it to the dealer for a check. The mechanic there recommended replacing the Torque Converter - a $4000 job, more or less.
Not wanting to spend that much unless it was necessary, I took it to my local mechanic. He says the torque converter is fine - that I would feel serious shaking and problems shifting if it needed replacement. And he said the grinding sound is normal for a car with so many miles on it. He says the differential gets noisy as the mileage goes up.
Who’s right? And if the problem is the differential, can I just keep driving it - as long as the noise doesn’t bother me?
