That really sounds like you might be low on fluid, I would have that serviced before it becomes expensive. It is also possible that your Mechatronic Adapter seal that holds the pressure from the valve body to the gearbox might be leaking. The seal is cheap at around 20.00, & it takes around a hour to drop the valve body & button everything back up. Adding the fluid back can be challenging the 1st time, but after that you will learn easier ways. The pan/filter, seals, & fluid will be around 300.00 for the parts. A shop will probably charge between 550.00 to 800.00.
