on a 1994 buick park avenue the car when cold and first started the trans makes a loud buzzing noise in park, when the car is put into drive or reverse will move about 75 feet and stop with what appears to be a slipping trans and will not move until cools down for half hour or so. The trans fluid is black in color and dont know if there is a trouble code that flashes for onboard engine computer. Our first plan is to pull trans pan and inspect, change filter and put pan back on and fill with new fluid. Any other suggestions if this does not work?
