I had my transmission rebuilt about 3 years age. My ABS light is on and my no trac light is on. My car is not shifting right. Sometimes when I would stop and shut the car off for a few minutes it would start shifting again. Could the cause of that be the transmission again or could it be something else.

    We tried the speed sensor and it is doing the same thing. Other codes that came up are PO 502, PO503, C1216, C1221, C1225, C1226,C1232, C1233, C1245, C1248. Help I hope this doesn't mean the transmission needs to be rebuilt.
