Took it to a mechanic, he did full transmission fluid and service apparently.
He apparently put 7 liters of fluid into it (which seems excessive to me) but then on the way home it started doing the same thing again but even worse.
A friend ran an OBDII on it today and it reported one DTC - P1890.
Does this mean that the gearbox is potentially damaged as I have read it may mean this, or perhaps a PCM issue?
What would you recommend I do consider I just paid $700 to have it addressed?
I can't really take it back to the original mechanic as he is over an hour and a half drive away.
I feel as though this is something he should have found if my friend managed to find the code that easily.
He does have a significant amount of experience working on cars so I am confident that what he has told me today is definitely correct as it is displaying all the symptoms he said it probably would have been doing.
