If it is sticky it will cause surging as you describe but does not throw fault codes. Try it.

Thanks Ferret. I have had the secondary drain mod fitted.

Just to close this one out.

the final fix was a full gearbox rebuild - in DArwin, but through AB in Victoria. Total cost $7860

Yes that hurt.

Jesus mate. Have you entirely rebuilt the car top to bottom while up there?

Prettt much, The list of things I’ve done in the last four months is very large - it’s going to be a brand new car soon, was going to sell it for a new one but may not have to now!!
