quick question
how do you change/drain the torque conveter for w201? do you need the rear wheels on jack stands to rotate the drive shaft?....actually, where is the torque converter? I need to completely drain mine ASAP, have too much fluid and it is dark brown......already have transmission problems, just don't need anymore. Thanks.

If you are laying under the car looking up....there is a small "window" where the transmission and engine meet, this is where the torque converter drain bolt is accessed. No need to jack up the rear. Just the front. All you need to do is crank the engine over until the allen head drain bolt becomes visible in this "window". Sometimes you will get lucky and it will be right there ready to be removed with no need to turn the engine over.
The torque converter fills itself with transmission fluid. You fill just the same in the trans fill hole near the firewall. You should drain the entire transmission too, since the fluid between the two is constantly mixed.

So I need to "crank" the engine until it eventually becomes visible? Sorta like roulette, or is there a way to turn it by hand via drive shaft?

Both times I've done it, the bolt was right there. The window is pretty good size. If it's not directly visible, you can usually see it, it's a matter of "bumping" the key a few times until it becomes visible. It's really simple. It shouldn't take you more than a few minutes....

Also you can turn motor by hand, the bolt on the crankshaft.

lsmalley, use a 27mm socket on the crankshaft pulley to turn the crankshaft until the torque converter drain plug is visible through the access hole. (Note: Only turn the crankshaft clockwise when facing the front of the engine. Turning the crankshaft backwards can damage timing components.)
When servicing the transmission remove the drain plugs from both the pan and the torque converter to drain all transmission fluid. Then remove the pan (which will likely still have some fluid in it) and replace the transmission filter and pan gasket before reassembly. Establish the proper transmission fluid level on the dipstick with the transmission at operating temperature. Be careful not to overfill.

is there another way.....don't have a 27 mm socket and how do I access the crankshaft anyways to turn it? do I need to disassemble anything?

Get an assistant and bump the starter. Without an assistance bumping the starter till it shows up is exhausting work - especially if you're the unlucky type.

I'm under the car and starting it, I have remote push button start, but I don't see it. I've tried several times. is this the right place I'm looking?

lsmalley, you're looking in the correct place. The torque converter drain plug takes an allen wrench to remove it. It's different than the oil pan and transmission drain plugs in case you didn't realize that.
You'll need to remove the sound encapsulation panel under the engine if you have one. The crankshaft pulley is readily accessible once the panel is off. Best to use a breaker bar with the 27mm socket for better leverage.

I used a screw driver as lee suggested and was able to use the cage as leverage as i rotated to get to the torque plug. Thanks guys. Ive always changed the tranny fluid and filter, but never did the torque converter, it was at least 3 qts in that thing and it was real murky looking.....now, check out my most recent post on idling
