I backed out of a parking space the other day and when I put the car (2004 Pontiac Grand Prix GTP) back in drive I heard a loud pop from the right front area of the vehicle. And then I noticed I couldn't move forward and it didn't feel like the transmission was engaging. So put it back in park, then shifted back to drive again. Still nothing.
At this point I was about to be blocking the intersection, but then I remembered the manual mode for tapshift. It clunked into 1st and I was able to drive away. I was in town where speed limits are under 35 mph, so only made it up to third. I made it back to the parking garage at the office, but the climb up the ramp in 1st gear was labored with lots of shuddering.
I did an overhaul back in December 2012 and it's been on the road until this week. Almost got another 5 years out of it and I'd love to get a couple more.
I was thinking broken forward band since they are original and that's probably the sound I heard. I didn't swap any of the bands out because they looked OK during the overhaul and I had other damage to the final drive area that got most of my attention (and budget at the time).
I checked the shifter cable and the range switch. They both look like they're functioning as designed. Reverse still works. I've parked it for the moment until I have time to fully diagnose.
Is it weird that I have no forward motion in Drive, but the car moves in manual/1st?
If anyone has any insight it would be much appreciated. I'm scratching my head on this one.
I'm going to tear into it when I get done traveling for work after Thanksgiving.
Thanks in advance.
