2000 Chevy Blazer 6 cyl Four Wheel Drive Automatic

I have a 2000 Blazer that about 2 days ago had the service engine soon light pop on. I took it to have it scanned and it came up with code PO740 only. My vehicle "seems" to be running fine, but not sure where to start checking. I'm afraid to take my car anywhere due to the fact that anytime anything that has the word " transmission comes up" They automatically want to replace or rebuild when that's not necessarily the issue (it's happened to me twice now and wasn't the problem) Can you please give me some advice on where to start?
Thanks
