Default 07 losing power in low gear acceleration

My 07 LTZ is losing power in low gear as I lightly press the accelerator. It gets to the pint that the whole truck will vibrate like it is going over rumble strips. As soon as I let off the gas it goes away. Or if it hits the next higher gear the chattering goes away. I have 100.000 miles on truck and just did a major tune up. Plugs,wires, fuel filter. This problem was also happening before tune up. That was one of the reasons I changed out plugs and wires. Any suggestions?,
Thanks

Torque convertor clutch? Just a SWAG.

I had very similiar problem I did not notice loss of power but I had all other symptoms you describe.

My issue was a bad u-joint on the drive shaft. The dealer said it was frozen and not moving freely.

Mine was even covered under the powertrain warranty.

Good Luck

I will have the dealer check it out this week. Im about 300 miles over powertrain warranty so if that is the problem I may have a warranty issue.
Thanks for the help.

Just got the answer to this issue from dealer. It is the torque converter. Man you are good. Great call.
Powertrain warranty will cover this.
Thanks again
