Low line pressure

Hi I have a Jeep liberty 2001 with the 45rfe auto box. Could dirty oil/filters cause the aouto box's low line pressure warning to show ? I took it to a private jeep workshop who said the oil was fine. He also plugged it into a computer and ran some kind of test on it which caused a lot of loud clanking as it changed gears which he said would tighten up/reset the gearbox ?. To me it sounded more like seriously stressing the gear box, any thoughts. He also said low line pressure in the aouto box is a common problem and not to be too concerned. Currently it is on 50,000 miles and the gear oil has never been changed. I have also been told it is not a good idea to change the gearbox oil unless absolutely necessary as doing this can cause problems

Should of been done, if you have 50,000 miles on it, I would go to the dealer and have it flushed and be good for a while.
Now if you had 150,000-175,000 then I wouldn't touch it
But a dealer is the only one who uses the correct fluid when flushing them
