trans problem?

I have a strong shudder with loss of power while under strong acceleration. There are no noises just the strong shudder throughout the truck (driveline). The entire truck shakes. I believe it only does it when the torque converter is locked. Everything else is ok. Any ideas as to what the cause may be?

Usually, it's one or more cylinders misfiring.

After reading a little bit, I am leaning toward u joints, or carrier bearing. Injectors are brand new. I had a bad injector which resembles more of a miss. This was a constant shuddering under throttle.

I'm betting 100 internet shekels on the carrier bearing.

I ended up checking the injector hold down bolts. I found the bolts a little loose. I was able to get about a half turn on the bolts until they reached 120 inch lbs. I am not sure if that would cause the shudder.

I'll bet 1 U joint. (If we're still allowed to say that)

Bad HPOP. It would loose psi randomly.
