6.0 torque converter problems?

When my tranny is not at operating temperature and the torque converter locks in 5th gear around 50 mph the truck starts to vibrate real bad if i get on the gas.

I thought it was maybe the death wobble but it doesn't make sense because it dosn't happen when the tranny is warm and it isn't cause by bumps in the road or anything, just if i try to accelerate with it locked.

i don't have any codes.
Any ideas?

My idea is that you have a misfire when cold.

Re: 6.0 torque converter problems?

tranny fluid is full

what would a misfire come from?

that makes sense i guess because the torque converter locking is putting extra load on the engine?

Re: 6.0 torque converter problems?

The misfire comes from a bad injector most of the time. Misfires are easiest to detect in overdrive with the converter locked. They really stand out with the high load.

I say sticky/failed injectors or a bad FICM. I'm calling it now. : )
