Hello and welcome to JustAnswer!

P0733 is a gear ratio error in third gear, P0734 in fourth, P0735 is a gear ratio error in fifth. These codes set when the input and output speed sensor signals don't agree, usually because the trans is actually slipping.

You may have a clutch issue but it's possible that the problem is related to the fluid change. If the sump filter seal wasn't installed correctly then the pump could be sucking air which will drop line pressure.

Did the problem start after the fluid was changed or before?

after fluid flush, seal that was installed was threaded instead of smooth like old was

This is the seal in question. Where did you install this seal?
