Hi , I have a 1996 buick riviera and when I got it started and put it in gear it took off very slow and did not change gears .so I put a used trans in it with very low miles (under 70,000) and it did the same thing as the trans that I took out. it takesoff very slow before it pickup speed and it does not shift gears . can you please help me because I know its not the trans, could it be a sensor or solenoid ?????
