Has anyone ever heard of a pressure drop test when having your transmission flushed? In other words, we didn't change your filter because the pressure drop, or lack of, showed it didn't need to be changed.:confused:

Never heard of it.

moving to tranny section.

Sorry, didn't even notice there was a tranny section:o:

never heard that one b4 don't now how you would get an accurate reading on the filter from outside the trans since it is on the intake side of the pump and the trans cooler lines that im assuming they are checking the pressure at are on the other side pressure side after the pressure regulator because you dont want cooler pressure to increase with rpm
