I have an 06 FX4 supercrew. Mechanic just rebuilt tranny, changed plugs, cleaned maf, and it still shudders at idle. He suggested having the computer reset at the dealership. Anyone have any ideas?? Already spent $2000 on repairs.

What RPM does it idle at? I thought there was a re-flash to fix low idle? Maybe I'm wrong.
If the COP is misfiring, wouldnt there be a check engine light? I'm curious because my pops 04 has what feels like a misfire at highway speeds under load and he thinks its tranny but I think it just needs plugs and COP changed. Thing is, his doesnt have a CEL either. No codes stored in the system either.
