1986 Saturn SL1 Transmission

Hi I am currently in roled at ATI and I have already ask about this question to someone else there but I want to get some outside advice. My transmission in my 2001 saturn sl1 shifts hard going into second and sometimes third. It shifts harder the less I accelerate. If I floor the peddal it seems not to do it so much. I gave it a transmission flush about 3 months ago to see if it would fix the problem but it seemed to get worse. I have only owned it 6 months. It also makes a noise when I put it from park to drive and reverse. I was told it might be the trans. Pump. I dont know alot about trans. I havent taken that class yet and I want to learn. Should I just let the car go? Is it worth the fix? I know about all the problems saturn had the first 10 years. But if its worth it I will just fix the problem. I have already put money in to it for parts and replaced alot.
