weird noise with acceleration

07 jeep compass 4x4 with 5spd manual, 99k miles
my jeep drives normal, downshifts, cruises without any problems. but if you touch the gas there is a weird whine sound. let off the gas and it goes away. it is most noticeable in 4th and 5th gear. it sounds like the sound is towards the bottom of the engine, transmission area. but it is hard to tell from the drivers seat.
I changed transmission, transfer case and rear diff fluids when I bought the compass 1 year ago. I have double checked and everything is full. my tires are all the same with even wear. I'm not sure what else to check. any help would be appreciated. thanks

Does the noise change when stepping on the clutch? How is your reverse gear selection?

push the clutch and the noise goes away. no noise revving in neutral at any speed. its not noticeable in reverse. but it is most noticeable in 4th and fifth gear. I'm not sure if it is speed related some how.

Could be a thrust bearing, or a bearing on the lay shaft.
