So I drove the car up on ramps yesterday just to get the front end up off of the ground to do some maintenance...and nothing happened out of the ordinary. Then I back the car off of the ramps, realized I had forgotten to do something, and went to drive back up the ramps. At this point, the car in Drive, would not go up the ramps and the drivetrain made a whining sound (can't describe it very well). I literally pinned the throttle and it would not go forward. Backed up out of driveway, drove down the block and back into the driveway and the car went up the ramps fine. I am EXTREMELY confused.
