In the event that there is no dipstick, ATF levels are usually checked by removing the refill plug and checking if there is some ATF flowing out. Check usually done after warming up transmission. As long as there is ATF flowing out then level is sufficient. No need to drain ATF. Procedure to refill ATF is also the same. Refill until slight overflow.Hope this helps. If you do a seach there should be extensive discussions on whether to change or not to change BMW 'lifetime' ATF.
