...stopped moving!? On my way home from work last Thursday, (Extremely cold day too! 14 below!) my van was not having any problems. All of the sudden my speed started to decrease until finally I couldn't go anymore. The van stays on, but it will not go in reverse, drive, 1st, 2nd or 3rd. Nothing! There were no sings leading up to this, transmission was not slipping or anything. What could cause something like this?
