Hi all, I need some expert to help me out with the problem I'm having. I have an audi a4 1.8t 2003 automatic , milleage 65k, when I start to drive slowly from 0-20, the rpm start jumping once then go back to normal but when I put the pedal all the way the Rpm wasn't jumping at all. I took it to transmission shop and they said the transmission was okay. Is there anyone knows or happened to experience that situation before? The check engine is not on. Can someone help me? Thank you

Al
