91 Pontiac Grand Prix Will engage in reverse, but not in Drive

I was driving on an incline when the car started shuttering. I heard a pop, and my car would no longer engage in drive. It will still engage in reverse smoothly, but not drive.



Any ideas?

Bad news. You need a transmission rebuild or replacement.

anyone?

What happens when you drop it into L1 or L2??

Is this a 3 speed or 4 speed??

I hear a noise that sounds like a growl, but car doesn’t move at all. On the gear shift, there’s 1, 2, Drive, and Overdrive.
