transmission shutter at highway speeds
At speeds between 60 abd 75 mph I occasionally experience a shutter or slight loss of power. At one point the car lost all power. I pulled over and re-started the car and drove off normally. No warning lights are on. I only experience issues with a warm car at highway speeds. Does anyone have any ideas whats going on here? I have 92,000 miles, all fluids are changed and maintained according to the manual. The dealer said the couldn't do anything without a warning light to pull the code. I don't want to wait. I appreciate any advice. Thanks
