BeeRad said:I had a similar problem when I blew a head gasket. I guess it leaked oil into my transmission and it was making that whining sound when I excellerated at first but then it seemed like my transmission start slipping. Then it got really bad and I couldnt drive it without hard shifting, then it got worse all within about 20 minutes and I made it to my benz guy. So I am going to have to say Oil in the Transmission FTW
Head Gasket, those are fun to fix.
