Gearbox can be done with the right tools to compress the clutch packs correctly, patience and a decent vernier etc etc...
Torque Converter is a specialist item, they need to be cut open, rebuilt then welded back together.

Strange @Bemble hasn't responded.
Looking at his last post - this was 27th Feb so he may not have been online since then....Phil is a busy boy me thinks!
As Saint.V8 has already stated, the ZF transmissions are very straightforward to strip & rebuild. The hard bit is getting the damn thing out of the vehicle & back in again afterwards.
Worth having a glance through the Repair Manual to see what you think :

Don’t worry about the special service tools. Just about all of these can easily be improvised.

Typical conditions for shuddering (due to wear of the torque converter lock-up clutch friction plate) are at light throttle openings on a slight incline. This is because the LUC is operating in its ‘continuous slip’ mode, to minimise the transmission of torsional vibration through the driveline.
At high loads/higher throttle openings the LUC is either off (low speed, low gears) or fully engaged (higher gears, higher speeds). These are not usually conditions that create vibration.
If I were you, I would exhaust other possibilities before resorting to removing the transmission.

Am I correct in thinking that if the torque converter lock up clutch is the problem then the debris from the lock up clutch will be ingested by the gearbox?

Yes, the majority of the flow from the pump goes through the torque converter, which flushes the debris out into the fluid. Once the friction material has completely worn off the LUC friction plate, the steel backing plate then begins to wear, depositing metallic debris into the fluid.
This is a particularly common issue with the GM 5L40-E transmission fitted to 3.0l TD6 models.
You can see in the photo above that the GM transmission has a torsional vibration damper fitted in the lock-up clutch. The early 6-speed (& all the 5-speed) ZF transmissions don’t have a TV damper, but the later 6-speed & 8-speed models do.
