Which is why I'm asking. After the second repair failed it's obvious they're
not fixing the real problem.

What he's complaining about isn't a common fault with these gearboxes, but
"adding the wrong oil" is, and when high-sulphur oil is installed in any of
these boxes the issue he has with gear clash is exactly the symptom.
