Hi, new to the forum, hoping to find some help here. Here's my problem. I have a 00 Grand Prix GTP, driving home today, transmission stopped shifting. Stepped on the gas and nothing. Shifted up and down and barely made it home in 1st gear. Luckily was real close to house. So as it stands, car will shift in R fine, 1-2 barely moves, anything else the car won't move, just rev up. Before I take the car to a Transmission shop, is there anything I can check on my own? Maybe something simple? Fluid isn't too bad but could probably be changed soon. Or does it sound like this tranny might be shot. Engine light never came on. Any help or advice is greatly appreciated! Thank you!
BTW, this car has 160K.
