I have not done much with VW autos yet , but have rebuilt a number of fords ,chevys , chyr.
Pain is the ass stuff like not being able to do normal auto trans maintenance - no dip stick , no dip stick tube to easily add fluid , no ability to adjust bands for wear , no easy access for test pressures for diagnosis .
There may be other issues but a few as compared to trans I have worked on .
Then normal [ last 50 yrs + ] typical life life of A.T. with lack of maintenance 150 mile +/- .
See lots of VW trans running at 200 + miles [ wheres the problem ] nothing is perfect / does not have issues , but without having one driver driving all cars with A.T. for comparisons / seems like VW trans are not as problematic as forums / youtube talks about .
Since you just got this and have given little to no history [ millage ??? ] , I would not count on it , but if you drop the pan [ inspect whats in pan ] change filter & refill & test level ---- do not forget to measure what was drained out .
Then see if some performance came back .
So without you possibly knowing more , and us having more info , it's hard to say , except to do the service I mentioned [ or have someone that knows what to keep an eye out for ] to get an informed idea what you can expect ?
