Since M-B does not have a maintainance manual for my 1997 E320 I don't know how to change my tranny fluid and filter. Can anyone give me the steps to this procedure? Thanks in advance!!! Big Ron

Official word from MB on the 722.6 tranny is that it is a permament fill of tranny fluid. I changed mine at 70k miles. It has a drain on the pan and torque converter. Remove the pan to access the filter and then refill. You must use the special MB synthetic fluid. You also must know the tranny fluid temperature and purchase a dipstick as the car is not provided with one. Getting the fluid level right on this is very critical and not as straightforward as other trannys.

Thanks Ali, but where is the drain for the torque coverter? Big Ron
