Truck is 2012 1500 5.7L.
Shudder at 2000rpm, but not before and after that rpm. No shudder when flooring the gas during idle. No code. Mileage is 147,890. Transmission Fluid is newly replaced. Spark plug is due this weekend.

So while driving especially passing other car or uphill, I just manually downshift the gear to skip the shudder.

Clutch pack worn from down shifting at WOT.
RFE trans won't hold up .......that's why most downshift manually.

You may get lucky & only a valve body issue.

I appreciate your reply. How do I know if valve body has an issue? Is the solenoid the only thing that need to be change?

Yeah I missed that 148k on copper plugs could definitely cause a shudder in overdrive.

Yeah could be the plugs. Happened before but different situation. This time seems different because no shudder during idle.

Plugs will arrive tomorrow. I'll post the update after replacing them.
