On the way to orlando on Friday, my shifter started to rattle and then make weird noises. At first it sounded like "shhhhhhhhhhhhhhhhhhhhhhhhhhhhh". Now its like a "rrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrr" Low and somewhat high pitched. Oh and it only does it if you push on the gas, but as soon as you let off it stops. It does this through all the gears except for 1rst. Is my tranny going? What can I do to fix it?
