It's most likely your alternator starting to go bad. Your electronically controlled transmission requires a steady amount of juice to keep it running properly. When it doesn't get it, the transmission goes into limp mode which basically means it stays in 3rd gear. That's why you have to press the gas so much to get it to go. I would look first at the alternator and electricals. Can't fathom how the oil pump has anything to do with this problem.
