25 beeps on car startup?

I recently got my tranny replaced, and upon getting the car back I noticed that the car beeps 25 times once you turn the key. Was curious if anyone knows what this might be?

Here's a video for reference:

I thought it was the seatbelt maybe so I buckled up before starting the car. No dice. I also want to note that the beeping only begins when starting the car, doesn't do it in just the run position.

It's driving me nuts! Any clues would be great.

I counted 25 beeps. I can confirm your problem

Seriously, I have no idea why it's doing that. Have you pursued it with the the transmission shop? It may not help, but I think they need to be in the loop.

Looking at the video, I didn't see any unusual warning lights. But I'm wondering if there are any codes. You might get it scanned.

I can think of all sorts of wild guesses, from bad ignition switch to user setting (such as selecting one beep or two when locking the car with the fob). But I can't recall ever seeing one for "25 beeps when starting"

One thought that keeps coming back is that it is indeed some sort of warning or status indicator. For example, I seem to recall that, on some vehicles, the MIL/CEL codes can be read by counting beeps or light flashes. But that's a vague notion, and may be a bum steer.

Besides posting on Chevy/GM forums, another place to check is the dealership. Go in and speak with a service writer, and ask if they're familiar with this anomaly. You might go to two or three places. But, if it's a known condition, somebody ought to be able to tell you about it without you paying a 100 dollar diagnostic fee first.

That said, I see you're posting in the B-body sub-forum, so your car is likely more than 20 years old - the service writers may not be up to speed on it.

Have you inspected the transmission to see if maybe there's a cable left unplugged? With a car of that vintage, the transmission may work just fine without it, but maybe the body computer is trying to alert the open connection.

HTH.

If your socket set is all the same brand, you might be a city slicker.
