I have a 4T65E Trans. After about 30 miles driving at about 70mph, then driving around 25 - 30 mph, especially putting the selector in first gear. I hear a loud whining noise. The trans fluid was really high on the dipstick, past the bend. I let the car idle for 3 or 4 minutes still high. The fluid looks good.
