Gearbox noise, TC or mech unit?

I fitted a second hand gearbox not so long ago (old one had a TC vibration and one at 40mph)

New gearbox has cured the vibration at 40 and the vibration from the TC but now I have a noise like 2 metal plates grinding against eachother when I come off the throttle, or when I'm under very very light loads.

I have a spare mechatronic unit from the old box still that I have debated fitting in, incase the cables are sticking.

Sound like a possible cause or is it the TC on its way out again 😭

There is nothing on the valve body that can make noise, even the solenoids wouldn't be noticeable so swapping the mechatronic wont solve anything.
