I was on the express way and I heard a pop noise when I was driving, when I got to my destination I noticed I couldn’t reverse any thoughts or suggestions? ---

What year, miles, and engine? When was the last time the transmission fluid was changed? ---

Beyond checking the transmission fluid level for proper fill, perhaps checking the linkages, there’s not much a diy’er can do when their automatic transmission won’t shift into reverse except to make an appointment at their auto repair shop or transmission shop. ---

Nice car. As SMB said, find a good, independent transmission shop. Bring a wheelbarrow full of cash, too. ---

This transmission is just an old-school 4 speed automatic, complete with vacuum modulator. Doesn’t have any computer controls. I believe the only solenoid is for kick-down It should . . . theoretically . . . be a breeze for an experienced trans guy to rebuild/repair. There’s actually no shortage of diagnostic and repair manuals available. And I’m talking manuals specifically geared towards trans rebuilders
