Elegtrical Gremlins?

[1low1]

HI all i'm new here because i NEED help. I have a 2003 silverado 2500HD 4x4 6.0l . I just bought it so i have little history. When i firts drove it the speedo needle jumped arounf occasionally and the tranny would not shift properly when the needle did this, also the ABS and EBRAKE lights came on. I changed the speed sensor and everything seemed fine for a day. I parked it with everything working and pulled the driveshaft for a few days re-installed it and now i have the ABS and EBRAKE lights no speedo at all and it shifts fine (although slightly hard) Also my ODOMETER work fine prior to speed sensor change and after but after driveshaft change nothing. Any help would obviously be aappreciated.

You will have a SES light and you need to have the codes read before we can help.
