2004 Suzuki Verona: the transmission starts off in third gear..idle Here's one for you ..... My Verona started doing the same thing . Checked the code (crankshaft sensor A low voltage) cleared the code , but it came back ...Checked all fuses, all OK.. Started the car , while running pulled the fuse for trans control mod . Light stop flashing ... Put the fuse back in . No more shift problems .....
