I've only posted a few times here because I'm very keen on utilizing the search function on this great forum. Since owning my 2002 Grand Prix GTP since December 2012, I've had just about every common issue come up with these and have been able to fix them pretty easily. I've had the steering rack leak, water in the floorboard, keys stuck, shifter stuck in park, P0102 code, so on and so forth. Outside of the rack, these were all really quick, easy fixes and expected for a car with nearly 150k miles. I'm afraid that is likely no longer the case.
My current problem, as the title states, is that my transmission had Drive and 3rd go out yesterday, unceremoniously to say the least. There was no thud, no whine, no slip, no SES code, nothing. Simply turned the car back on in the parking lot and she didn't engage into drive at all. There has been no obvious issues with the transmission before this. I still have reverse, 2nd, and 1st working so I was able to get it home. I first thought it was something electrical, given how sudden and unexpected it happened. But, as I continued to read, BillBoost had posted elsewhere that leads me to believe it is a broken forward band rather confidently.
I am pretty schooled on everything car related except for transmissions. I believe a diagnostic test runs about $50 locally, but with what I've read, I'm about 98% sure its the forward band issue. I know anything transmission related is serious money. Is it worth repairing or replacing? What should I be planning on spending? Should I expect a decent car life after either or more problems down the road? Sorry for the silly questions, but I literally have never had trans issues on a car.
Any information that can help me make a sound, educated decision moving forward will be really appreciated!
