Hello, I am from Poland and I apologize in advance as I write something wrong. I have an acccord 04r automatic gearbox. The problem is that as I push the gas to the end it does not want to change gear to higher, the rpm goes up and does not change gear eg from 1 to 2 of 2 to 3 and so with every run is the same. No errors in the gearbox is there, please help where to find the cause, oil and filter replaced.

 

Pressure Switches could be going bad or already have. Here is a video for an 03 same motor and tranny
