1996 Chrysler Concorde lx need help

I just got the car from my uncle. It has 140000KM on it and won't start until i prime it 3 to 4 times. When it starts the speedometer shows between 60 to 80KM and the odometer is running as if you are driving it down the road, when you shift it from park to drive it stops. Sometimes the transmission will not engage in any gear. The car idles between 800 to1000 rpm. The only code's that come up are 24,47,54. Any help please.

Probably Input And Output Speed Sensors On Trans. I'm Not Sure What Those Codes Are Though.
