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?
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 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.
