[Quicksilver500]

MB uses regular Dex III so just use that, if you switch fluid this late in the game you can strip the clutch material off the clutches, I know, I did it. You should flush it every 30K and it can't hurt it. When you get it rebuilt use something of better quality and synth 722.6 fluid is good...but for now just keep using whats already in it which is probably Dextron III. Drain the pain, take it off, clean it, replace the filter, make sure you get the old seals from the old filter off the valve body, put it all back together. The tq spec on the pan bolts is like 12-14nm, don't over torque! and tighten in a "star pattern", if you over torque the bolts you will bend the pan and it will leak, they are like 50$. Make sure to drain the torque converter too. Put like 3 or 4 quarts in, turn the car on and shift between the gears to get it circulating then you put enough to make 7qts and then top it off as necessary. If you put all 7-8 in at once the tranny will think its over filled and blow out of the top. Good luck, its really easy. You need a 5mm allen, 13mm socket, a big screwdriver (to rotate the tq converter), and a philips head screw driver.
