1994 Buick RoadMaster Station Wagon 350ci, with 75000 miles. While driving at speed, if trying to accelerate, the car will shake when it attempts to downshift just one gear. Does not happen when pushing the gas in all the way, but only when it downshifts one gear. It also happens occasionally when leaving a stop a stop, the car will shake, and barely accelerate, like it can't get into gear. I took it to a shop, and they couldn't get it to do anything, so I had them replace the torque converter lock up switch, but that still didn't fix the problem. Any suggestions?
have the same problem?
