My car was going pretty good despite its high mileage. I was leaving work and when I started to drive away I noticed what sounded like a distant jet plane. I slowed down and the noise went away, but when I got on the highway I noticed a vibration in the floor and it periodicaly sounded as if componants were rubbing together inside the transmission. Like a dull roar or grind. The fluid has ok smell and good color and the guy I bought it from said the transmission had been rebuilt and I believed him by the way it operated. Can you help?

The only thing I can say is get it to a transmission place and have it checked. but before you do that did you notice a loss of power as if the car was running out of gas. The reason I ask is with you saying it sounded like a jet engine my first thought is the cadtalytic converter would make a sound like distand jet engine
