Help, I have an odd shifting problem that I hope has a simple answer. I'm getting 2 codes: P0914- Gear shift position circuit, and P0500 - Speed sensor A. Not sure if they're related but it seems likely. Also when I drive it it starts in 2nd and shifts straight to 4th. I can't get it into 1st, 3rd or 5th. The tranny sounds fine and the clutch actuator was replaced shortly before I bought it which was last week. When I turn the key I have to put my foot on the brake and I get the 3 bars for about 10 seconds then changes to Park, then starts right up. Any advice would be greatly appreciated.
