2008 phaeton, mh-3000 Allison trans. I am getting cat eyes and constant red Mode light on the shift control. Pushing or holding any and all buttons or combination of buttons make no difference. All fuses have been checked, TCM removed and checked. Thought coach was not going into gear but discovered it was. Coach drives, trans shifts like before. Has anyone had this problem and what was the fix?
