If the trans has no issues such as harsh shifting, slipping, delayed response, it should be ok. Here is a description of the trans operations which employs a grade logic control system.
Under normal circumstances, the shifting would be governed by throttle opening, vehicle speed and engine performance.
If the engine has any issues, the timing for the shifting might be delayed as it is taking longer for the vehicle speed to build up. Since your mechanic mentioned an issue with the engine, it could be possible and you should have a look at it.
