Mileage? What is the fluid level at? What's the fluid color? Have you towed anything?

heythe car has 71000 kilometers(canada)45000 miles,fluid is good do haul a small utily trailer once or twice a year no big weight though

All gears or just going from one gear to another. Is it still under warranty. Have a line perssure check done (idle and stall) when the problem is there and compare to the specs. Hopefully the dealership (when they start working on diagnosing the problem) will actually do tests and take measurements rather than assuming what the problem could be.
