Default Issues after harmonic balancer replacement

Hi all,
help request please, I have just replaced the harmonic balancer (crank pulley ) in the U.K. , on my 06 C6 automatic , all went well, rack off, starter of , etc etc, rebuilt it all back up and all appeared well until I tried to drive it! The car will not change into second gear and cannot understand if there is a link to anything I could have done, the car has only covered 32000 miles and the gear box was working perfectly before this work was carried out, can anyone provide any advice as to what if anything I have missed
thanks in advance
Tony

Hi,
no not fixing a wrecked Vette, the opposite in fact, a mint condition 06, I have read the OBD thread and appreciate your help, all appears ok so will start with fluid/ filter change when parts arrive as a precaution
thanks again
