A torque converter is rarely malfunctioning...
It's a pure mechanical thing with a turbine and an impeller. No contact, just oil flow.
In your case I believe that it is the valve block, if not the oil itself.
One or more valves that are regulating the oil flow and pressures for the clutches and/or the brakes inside are stuck or malfunctioning.
If you feel a shudder on 1-2 gear change then the SLB1 valve is malfunctioning among others.
You should also feel a slight shudder on 5-6 gear change, but there the torque is minimal and you hardly feel it.
If they insist on changing the torque converter, as this will mean to change the oil also, you could tell them to first check the oil, or even change it, before opening the box. You may have a surprise...
