Jack up car.

Drain transmission.

Remove the 4 bolts that hold on drain pan.

Spill tranny fluid -- keep the drain pan handy! You will always spill some off the pan. At least MB give you a drain plug -- american trannys used to drain by loosening the pan bolts and letting the fluid pour out.....

Unscrew the two or three screws holding the old filter on. Watch for more fluid when you pull it down.

Install new filter.

Remove old gasket from pan.

Clean edge of pan and dry. Install new gasket.

Wipe seal surface on tranny clean. Use some solvent to get everything off, even oil.

Thump pan on tranny untill the gasket seat -- thump will turn into a "clop" sound -- much sharper, can't miss the change unless you are deaf, and you can feel it, too.

Re-install the four bolt, don't over tighten, you will distort the pan and it will leak.

Take car off jackstands.

Refill tranny by putting two quarts of fluid in, start engine, them putting shift lever in all gears, ending in park.

Check fluid, then SLOWLY add more, checking after each addition, til you hit the ADD or COLD mark. Drive car to get tranny hot, check and adjust fluid and check for pan leaks.

Best to drain the torque converter at the same time, in which case add three quarts to start, total is 5, I think.

Be very carefull not to overfill, this can ruin the tranny.
