Do the rodney flush first. Then, be very careful to get exactly the right of fluid back in. These transmissions are very fickle about the proper level. It took me 3 times, drivng around the block and checking, filling, checking, driving etc ...to get it just right. After I did, all my issues went away.
You need the correct fluid level after you replace the fluid!!!
