700r4 howling in 3rd gear
I recently had my 700r4 rebuilt, it has a reverse pattern full manual valvebody. It drives well and shifts firm as it should, although I noticed a howl coming from the transmission. It is only in 3rd gear, loudest under light throttle application. I plan on pulling the trans back out so it can be gone through but I was wondering if anyone had any ideas beforehand. I attached a video of the noise in question.

It would most likely be the Front Planet.
