What's this noise?

Anyone know what this noise could be?
I’ve done water pump and timing belt about 10k miles ago
Truck sits at 190,900 miles
Shifts good too

Here’s a link for the video
Appreciate anyone’s help

 

My guess air blowing through a hole creating the sound

Noises will drive you crazy they are so hard to pin down

 

Oh that sounds bad. Park it until the community figures it out. Sounds like it varies with rpm?

 

Rpm’s don’t seem to be out of whack at all trans gos through every gear

 

Where's the sound originating from?

 

Power steering fluid level is good?

 

Power steering fluid isn’t full. But not low either. Sound looks like it’s coming from transmission. Maybe oil pump ?

 

Thank y’all for the help on ideas

 

If you're able to, put it up on jackstands on a flat surface with all four tires off the ground. Put it in gear( is that 2nd?)And crawl under the truck & listen at the bell housing back to the tranny oil pan. To see

That recommendation though is pretty dangerous & I wouldn't use anything less than four 6 ton jackstands & only if you feel comfortable doing so.

 

The noise stopped on it own stilling taking it to Toyota

 

A noise that goes away by itself comes back by itself.

 

Took it to Toyota and they said transmission is fine. said it needs a couple belts. Idle pulley and 2 others. for the low low price of $940.00
