I just took my 2014 MDX Tech in because the RPM's would bounce around while accelerating and sometimes during cruise between 1500-3000 RPM. After two days the dealer says it was the torque converter and they have replaced it. The car only has 40,000 miles on it. Anyone have any thoughts on this one, the rep said they replace about 1 in every 2000-3000 of this model. Thought?
