02 avalanche transmission - memcgrath74 - 04-17-2007 01:10 AM

Got five different codes off a scanner:
1)P1860- manufacturer controlled transmission

2)P0740- TCC Circuit Malfunction

3)P0753- Shift Solenoid A circuit electrical

4)P0758- Shift Solenoid B circuit electrical

5)P0785- Shift/Timing Solenoid Malfunction

Could it be that there is one main problem causing these errors or is it that all could actually be a problem? Are these fixable or does it mean a new transmission or rebuilding? What about cost for problems such as these? Appreciate any input on this!!
