The car has erratic shifting. It seems as if the gears get stuck before they release especially when slowing down then taking off, like if you do a rolling stop or slow down at a traffic light but don't stop fully before accelerating again. It does not do it everytime you drive though. There is also a clicking coming from behind the dash. The actuator for air has gone bad.
