2013 MDX on acceleration will hesitate or surge at approx. 80 km/hr

Did “they” test drive vehicle during the diagnosis?

Hello, this vehicle does not have a timing chain, so i'm not certain what was repaired in reality. Testing must be performed with a diagnostic tool on board while driving. A total guess would be engagement of the torque converter happening around that speed, but this does not indicate a suggestion of failure or malfunction in that area. These vehicles are not known for powertrain concerns.
