Good morning,
The noise you hear, can you post a video of the noise so I can hear it?
The most common reason for this issue is the filter in the transmission being clogged and the front pump is starving for fluid.
I would start by changing the fluid and the filter and see if the noise goes away.

CHANGING TRANSMISSION FLUID
There is no need to change the transmission fluid unless the transmission is used under one or more of the following heavy duty conditions.
A: Repeated short trips
B: Driving on rough roads
C: Driving on dusty roads
D: Towing a trailer
If the vehicle is used under these conditions, change the fluid every 20,000 miles (32,000 km.)
There is no drain plug in the oil pan. Oil should be extracted with suitable suction device through the filler tube. Alternately the fluid can be drained by carefully removing the oil pan. Place a large drain pan under the oil pan, remove 13 bolts on the right, left and front sides of the oil pan and loosen 3 bolts on the rear side.
Drain the fluid carefully.
Hold the pan horizontally, remove the remaining 3 bolts and remove pan and gasket. Clean the oil pan and reinstall it with a new gasket. It is also recommended to replace the fixing bolts. Tighten 16 fixing bolts to 11 Nm (8 lb. ft.) torque.
