Default how to tell if a torque converter is bad

Ok I have a 93 Chevy c1500 with a 350, I was driving home and it started taking long shifts down and back to higher gears. I pulled over and turned it off then start it back up after checking the trans fluid now it revs high in park and slams hard into drive, Can it be my trans or my torque converter?

I don't have a scanner to get the code and auto zone cant do it because its a OBD 1. The level of the fluid is at the mark. The color is normal and the fluid don't smell burnt to me

sounds like a vacuum leak, crawl under there and have a look at your vacuum line going to the back of the trans
