Maybe nothing at all. The engine speed goes up before the transmission shifts. At low throttle it should probably shift before 3,500 rpm.
It could be your input transmission speed sensor. It could also be that your transmission fluid is old or worn out. It could also be that you have a bad transmission shift solenoid because those are pretty common to go out
