Wj WJ Transmission Rattling / Buzzing Noise

I'm going to take the Jeep to a transmission shop but I wanted to know your expert opinion first.

2000 Jeep Grand Cherokee V8 4.7L
545RFE transmission
QuadraDrive
~190k miles

Here is the story:

I changed the transmission fluid and filters October last year.
4000 miles later (beginning March) I parked the Jeep on the left side of the garage because of a front differential bearing issue (needed to save money to afford the repairs)
I've been turning the engine on every other week to keep the battery charged.
3 months later (2 weeks ago) I moved the Jeep to the right side of the garage to make some room.
Last Friday I moved the Jeep back to the left side of the garage and is when I noticed the rattling/buzzing noise coming from under the Jeep.
I crawled under the Jeep and it seems the noise is coming out of the transmission housing bell.
The noise last about 3 minutes then is gone.
Gears shift smoothly Park-Reverse-Drive back and forth no jumping no noise.
I took the Jeep to the local car wash (6 miles round trip) and no shifting issues or any lack of power. In fact, if you press the gas pedal you can feel how the Jeep immediately takes off.

What do you guys think?

By the way, do you guys know any good transmission shop in the Denver area.

Here is the link to the video. Noise starts by 0:10 and stops by 2:55

Thanks,
George

Mine does this too, same noise, Selec-track tho. It only lasts for 1 to 2 seconds right when shifted into reverse and stops. Weird noise, doesn't seem to affect anything, just a weird noise. Anyone have any ideas?

I'd use the search engine on hear, I'm pretty sure this has been covered and the answer was solonoids?? I think...

I've never actually searched anything for this issue because like I said it doesn't really affect anything, it's just a weird noise. Maybe I'll look into it if it's a simple fix

So ya a quick search turns out it's normal for me, 1 to 2 seconds of buzzing. OP's might need new solenoids however? Haha no idea.

I'm gonna give you an old tried and true infamous quote from the stealership:

"Your transmission needs to be rebuilt, price will be $4600 even."

1-2 seconds is normal. ALL Chrysler transmissions do it with a little age. It's the shift solenoid. 3 minutes is WAY too long to hear it though.
