2005 ACCORD automatic trans. problem

[tdmhasan]

There was a TPS problem problem in my accord than I changed tps.i set voltage 0.48-0.50. everything was ok.After a few months,When it changes from 4th to 5th speed, it began to slip but only little.it goes normal in 1 or 2 second.

But last week, while i was driving from 4th speed to 5th speed, it slipped totally,i mean it s like N when its on D5.

I ask my service they said, probably solenoid problem they are not sure, they say that should remove the whole transmission than they repair so it cost to much..

Is there anyone experience this kind of problem,Could you help please..

Thank You..

When was the last time the ATF was changed on the box? Was the filter done at the same time?

I'd start with the cheap options first. Is any error present on the ECU? (geabox?)
