Hey guys,
Over the last few weeks my 94 auto factory turbo truck has developed a rhythmic knock...I can really hear it resonate though my intake (cowl induction). Well this morning it went from wondering if something is wrong to what in the world is wrong! I have had a problem for a few years when the truck was hot it seemed like the torque converter would lock and then unlock while driving, while cruising the rpm would go up 200-500 while holding the pedal steady then come back down, and then a minute later it would do it again. I started a thread about this so I will try to dig it up incase it is relevant. So this morning while driving I noticed that the knocking noise was getting louder so I pulled over. It was bad enough that I thought I needed to turn around to try to make it home...I did not get that far before I pulled over and shut it down because it was getting worse. The converter kept locking and unlocking to the point where it really seemed to have trouble putting power to the ground, it was doing it's thing constantly rather than every once in a while, and I started getting a buzzing/clicking noise too. I checked my oil and coolant and both levels were fine. Can you all please give me your advice so I can figure out what is wrong with this thing. Please let me know what other information you need. The truck has 185k, auto 4x4.
Here is a video of when I first pulled over this morning and decided to turn around.

And here is the video about 5 minutes later when I decided not to drive any further. The engine I really shaking at this point and the truck really does not want to be driven.
