can you tell me what the make. model year and engine size and fuel type this is please?
also is it an automatic or manual transmission
OK 1st thing to ask is has the fluid level been checked and what fluid was used?
and is this a true automatic with a gear selector or the SMG automated manual?
from your description it sounds like either there's no or very low fluid in the box ( if its a normal auto) or if its an SMG then the clutch may need calibration
so this is an auto then?
what fluid are you using and how much has gone in so far?
OK so so if you run the engine and move the gear selector through every position and let it sit in each position for 5 seconds
then recheck the level
if its still full ( running out of the fill hole) then it sounds like the transmission has not been built correctly as what your're describing sounds like bearing noise on the input shaft
ok try running it for a few minutes and move the selector through each position
then switch off and check the level again
let me know how you get on
