My 1998 C230 has 107K on the OEM trans. fluid which the car shifts fine . Looks straightforward to change it . Can you guys w/experience check and advise my proposed procedure and materials ?

Here is what I would plan to do :

1. warm it up a bit then put on lift , drop the trans pan
2. collect about 4 of the 8 quarts of fluid
3. see if I can drain the torque converter ( drain bolt ? or jog it w/starter?)
4. replace old filter w/ new-guess I can see it w/ pan removed .
5. replace old gasket w/new
6. bolt up pan --cross pattern bolt tightening
7. remove dipstick ( is it sealed there?) and add same amount of fluid removed- what fluid to use ? Dex III ? or Mercedes Lifetime ? or ?
8. warm to 80C and check level -add if necessary
9. road test and check for leaks
10. Have cold beverage
Thanks for any help --Mark in S.C.
