I was changing the auto-transmission oil of my 190E 2.3 and I noticed that it's hard to get into the torque converter to drain it also. I'd like to leave the torque converter undrained and simply replace the oil from the main pan. How much of the 7.0 quarts remain in the torque converter? The manual recommends 6.0 for flush and refill, but I don't know if this includes the torque converter.

You once you drain just the pan and refill (be careful, don't overfill) drive the car around a few miles and make sure you put it through all the gears, including reverse. Then jack it up and drain the pan again. Once all the new fluid gets circulated into the Toruqe Convertor, changing it again with fresh ATF should have you covered.

You can rotate the engine clockwise with a 27mm socket and remove the drain plug from the torque converter with a 5mm allen. Then be sure to use an aluminum seal for the torque converter and a copper on for the drain pan.
The converter holds aprox 3 QTS.

Just did the same job on my 190e. Got to the torque converter drain by using a remote starter. That way, you can lay under the car and watch the torque converter as you activate the starter in small increments. You don't have to have another person to help you turn the engine over. I believe that my job used about 6.5 quarts of fluid. You should start with 3-4 quarts first, start the engine and put the trans through all of its gears. Add the remainder of the 6 quarts, restart engine and go through gears again. The last half quart or so should be added in very small amounts with repeated monitoring of the dipstick for the correct levels. You might also consider draining the fluid in the cooler by disconnecting the lines which go to the radiator. Hope this helps, bkim
