I would use a cheater pipe like I did on my ‘94 Blazer. I have a 2.5 foot pipe that I can put on my 1/2” drive breaker bar that gives me about 3 feet of leverage. Just make sure you have a good bite on the bolt and no slack in the pipe and just move it enough to break it loose. Then do it once more with just the breaker bar. That’s how I did mine. Two steps. I know on the torque converter bolts you probably can’t get a socket on so just get a good box end wrench and slide your pipe over it. Then get a pry bar with a thin head and get a couple of good bites on the side between the engine and transmission and wiggle that ****** till it breaks loose. Double check to make sure you have ALL the bolts out first!
