i was driving my car after being out of town for more than six months and it took a second to go into reverse which it always has... it goes right into first but not into second or third it completly skips those gears after revving real high for a second then after i let off the gas it goes into fourth no matter how fast, i noticed my shifter doesnt line up like it used to, the dash says 2, or 3 but it is in 1 on the selector i got a code p0703 how do i fix this? please help i need my car back to the way it was!!! thanks
