I guess I wasn't clear in my post. I understand how to change the fluid and have the manual on CD. I want to verify ( not estimate or guess) level of fluid after changing out the seeping NA electrical connector. The only way I know to do that is to put a dipstick in the tube hence the original question. However today MB dealer will check it after I do the TSB on the connecter and refill with new fluid the same amount that came out while removing the connector. As far as I can tell no Crosfire owner in Tucson owns a tranmission dipstick for the 722 transmission so the point is now moot.
