2000 Blazer 4wd 88K miles

My wife calls me when she gets to work today and said the blazer was shifting really funny on her way to work. In her words, it was really jerky. Then at one time she said she heard a loud clunk noise, but continued to work with the truck still not shifting right. On her way home the service engine soon light came on and the truck was still shifting strangely. When I got home I went to move the truck over to the other garage and there was no reverse. It certainly isn't shifting right, seems to stay in gear too long reaching higher than normal rpm's before shifting. Did some searching on the site, sounds like maybe the "sunshell gear"? I'm hoping not. She talked to a mechanic at work and he was thinking it might need a tranny fluid and filter change. Hasn't had one in a long time. But at the time, she didn't mention the loud clunk and was not aware that she had no reverse gear. What's the verdict?
