(89661-60250) ECU problem

[GV001CX]

Hello dear members. I have problem with my kzj78. 1 week ago to my vehicle 4th shift was lost, no o/d off, went to the electric and he told me that is ECU problem. It was realy like this, was something demaged inside. He fixed it and install back. After 1 day same problem. I called him and he is tolding me that: this problem is coming from gear box (automatic). Maybe solenoid problem and damages ECU. How do you think can be it really true?

Did he replace all capacitors? Highly unlikely that it's something damaging it, did he say what part he actually replaced?
