Plan on replacing the transmission. They are computer controlled and so it is always adjusting the pressures to make a nice shift for the driver. Basically so you don't know it's going to take a crap untill it does. But, the big failure is the bearings and races they use in the trans. They cant take it and fail. So, plan on replacing the trans and making sure that when you do you make certine that you have the latest brain for it.
