1998 Chevy Tahoe V8 All Wheel Drive Automatic

i have a 98 chevy tahoe and I currently replaced the transmission so now I am in the process of getting it smogged well the problem is that when I went to get it smogged the the guy said the oxygen sensor the catalyst and the evap system were not ready he told me to take it on a drive at about 60 mph on the highway for 20 minutes as I was doing so the service engine light came on so I took it back and it said that the catalyst and oxygen sensor were still not ready but the evap was but he couldnt do the smog because the service engine light was on and it would not pass can you tell me what the problem is?

What is the code of the service light? Have the computer scanned at autozone or a place like that - they will give you the code and they will do it for free.
