Batman,
I have the same problem with my windsheild darkening. Se3ems to happen every 24 hours around 5pm. BUT, in the summer it happens a little later.
A dealer told me the brake pedal going to the floor was normal, and that if the transmission has the proper input, it will skip over second and third gear and go directly into Overdirve. No Really, Herb Chambers Dodge in Danvers, MA really told me this.
