I have a 2000 dodge ram 1500, 5.9 litter sport..... My first to second gear shifts at 3000 rpm, second to third gear shifts at a normal 2000 rpm and from third to forth gear also shifts at a high rpm.... My check engine light is on so i checked the codes and it came up with, p-0500, p-0463. So far i replaced the transmission speed sensor, and the throttle valve cable. And still the same problem, can anyone please offer me some advice...thank you.(i know the p-0463 has to do with the speedometer)

 

463 has something to do with fuel level. 500 is speed signal. Is your abs and brake light on by any chance? You should replace the sensor on top of the rear end housing regardless.
