That is what happens today. With all our technology, if there isn't a code, the mechanic is lost. I hate to admit, it becomes a guessing game without the computer, but that is what being a mechanic was all about years ago. Diagnose the problem without a computer.
I have to be honest, it sounds like the transmission is slipping for you. That problem will not show a trouble code. Did the trans tech drive the vehicle?
