I never said that you didn't have a torque converter. Of course you have a torque converter. What I said is that your don't have a drain plug on your torque converter. You cannot perform step #7 since you have no drain plug. That procedure is for a 1997. As I said above, the drain plug disappeared after the 1999 model year. A search will lead to several options:
1. Drain the 4 liters or so in the pan only and be happy.
2. Do #1 a couple of times over a month or two to get most of the ATF changed. Once gets about 50%. Twice gets you up to about 75%, etc.
3. Have the transmission flushed which forces new ATF into the system. I personally would never do this on my car.
4. Disconnect one of the cooler lines and fill until fresh fluid appears.
Transmission can be in P when you do the job. Easiest method for you is #1 or #2. Always change the filter.
Oh, my bad about the plug. =) You're the man!
Here are some pictures I got this morning. Took the car on ramps. Not too much space but enough to perform "dropping the pan" procedure!
Yeah, you're right the 170.449 (
(late 1999-early 2004) has 722.616 transmission without the drain plug on the torque converter.
I can see a drain plug on the left.
Here are the plastic caps to the torque converter.
I just wonder what is the hose that connects to the transmission?!
I found this post on BenzWorld Flushed my tranny - Benzworld.org - Mercedes-Benz Discussion Forum
"yumling" removed plastic tubing that attaches to Air Filter housing. Then he put a clear plastic 5/8 tube on it and flushed the tranny liter by liter. I think that's what I'm going to do. I just want everything to be as clean as possible!
I also have one more question. On our old Montero Sport when we were changing the engine oil with our dad, when almost all the oil was out we used the air compressor to "push out" the maximum leftover oil from the engine. We used a rag to close the oil cap hole and inserted the compressor hose with the trigger-shape connector and pushed the pressure through the engine at lower psi.
Is it possible to do with the transmission? For example if i stick pressure hose into the dipstick hole? Will it push the rest of the oil? Or pressure is not recommended. Don't want to mess up things
