Took the car to the car wash, and after they finished cleaning the interior, car went into limp mode. It will not shift higher than 2nd gear, CEL on, gear display on dash blank, when put in drive cannot put into park unless you shut car off and restart. Using scantool.net get error code P0705 and attempted to clear error to no avail. What do I do next, without having to take to the dealer? Thanks in advance!!!
