drain plug

OOOOOH! that is very important information. I understood there was a drain plug on the converter in front of the pan. But I think the information I was looking at was for an older car. You are right, if you only drain the pan you can only change 4 quarts at a time. All the more reason to do it more frequently!!!

My overall plan for her car is to just drain it out the pan drain plug every 15k miles (of which I've got a couple of thousand left before that happens) and then change the filter every 30k miles.

Another note of interest here is that if you have a good service writer (like an ex-shop foreman) that knows what he is doing and is confident in your abilities to perform maintenance correctly, he will make a note in your maintenance book and stamp it!!

I know when her car hit 30k miles I changed all of the fluids, filters etc. etc. and put in a new set of spark plugs. I took him the book and he stamped it.

This is right form ALLDATA concerning the tranny in my wifes 00 230. I tried to attach the image of the dip stick, not sure if it's going to work though, so here goes.......


MB Automatic Transmission Fluid (Part Number 001 989 21 03 10) is the ONLY fluid that is approved for use in automatic transmission 722.6 .

Electronically controlled five speed automatic transmission 722.6 is filled with a newly developed special transmission fluid and is considered to be "filled for life", ie: does not require fluid level checking or fluid change during scheduled maintenance procedures.

No other fluid may be filled or added into transmission 722.6.
This fluid is not approved for use in any other automatic transmission series.

If checking transmission, fluid level becomes necessary due to repairs or diagnosis, please observe the following information:












B 80°C (180°F)
A 25°C (77°F)

722.6 transmission dipstick, special tool no. 140 589 15 21 00, is longer than is required to permit use on several different applications.

Insert dipstick only as far as end stop permits.

Please observe all fluid level checking and filling guidelines.

NOTE: Red locking clip (93a) (Part number 140 991 00 55) will break off and be destroyed during replacement each time it is removed.

oil dipstick info

Much Obliged for this information!! I assume that the dipstick is used as a tool, only to check the fluid level, correct?, i.e. you should still use the locking cap? in 1999 and later cars the dipstick is not included and you only get the locking cap.

Yes the dipstick is just a tool, you have to reinstall the locking cap when your done. I just safety wire the lock so it doesn't come off when I'm done and viola, fresh fluid.

Your 99 should have a drain plug in the convertor, and your 2000 "might" as well. The elimination of the drains was started in 2000, so if you have an early 00 than you just might be one of the lucky ones and have a drain.

It only takes a second to look under there and find out.

Also I'm doing some research in ALLDATA trying to figure out where tranny temp. sensor is and what pin it is associated to. It might be possible to get a reading of the fluid temp using a stardard VOM meter for all of those out there who are adamant about the temp. being 80'C. I'll let everyone know if I can find it.

This definitely sounds like an aircraft guy to me! Very good thing to do.

Have a great day

Larry,

Been one for over 15 years for a major airline. I'm just hoping to be one for another 15 years so I can retire at a young age. Economics aren't in my favor right now but at least our company is one of the ones hurting the least. For Now!!

Thanks for all the comments on the tyranny service!

John S. are you comfortable with transmission service at 100 klickometers? Why do you think Stu suggests 30K mile (~50 kilometer) intervals? (Now there is a loaded question)

Do you know off-hand the service interval is on the previous generation of transmission? BTW, since when do you have ~699 posts?

JCE, have you had an outcome to the growing epic saga that is Beowulf’s transmission?

Dale, thanks for all the information! BTW do you elevate your 722.6 or is it accessible when the car is on it’s tires?

Regards

Tracy,

The shop foreman let me walk through them doing the tranny service, and I winced when they dropped the pan. I didn't want to see what the fluid would look like after about 55K-miles.

Well, it looked just like the stuff they poured in. Like brand new!!

That gave me a comfort level with this particular interval.

The service interval on the previous hydraulic .3/.4 trannies is the 30K-mile mark. Not sure which tranny Stu is talking about, could it be the .4?

Tracy,

I use ramps to elevate the car enough to do anything under it. That just barely gives me enough room to work on what I need to do. My next garage will have a lift in it, at least that's what I keep telling myself!!

Tracy:

The trans feels as if it slipped twice since February, and there are 2 codes that come up according to my indie tech. The dealership gave me a refund on the Heritage warranty they sold me which would 'cover the problem' (but wouldn't when it had to go back in for the third time!). They 'noted it on my history so they could 'consider' goodwill repair if it goesout within a 'reasonable time'. If there is going to be a factory warranty on the trans as Mark implied above, I will feel a little better, but I noticed another thread where someone said this trans (?) had failed just out of warranty on their 97 E320, and the dealer wanted $8k to repair!

Thanks for the feedback!

John S, the article doesn’t specify other than newer transmissions with a lifetime fill, so I guess that’s the .5. Stu’s comments, in part are: “We stick to the 30,000 mile change, but synthetic oil is no excuse for extending change intervals. It is an excuse for disaster. One of our mechanics became a shop foreman at a large Mercedes-Benz dealer. He tells tails about sealed transmissions reaching 70,000 or 75,000 miles; when the pull the pans, the stuff that comes out is unbelievable”

So I have to guess that there is no harm other than cost by changing it earlier. Based on the above, I guess it can easily be put off until around 40K miles... Or.....

Dale, thanks! I’d love a garage with a lift, too! I saw an add for a lift for about 2500, only problem is raising the ceiling enough to permit it to work!

John, not that I would suggest the following, but if the transmission fluid were to get unusually low for some reason...... On the other hand, how often have you changed the fluid in the transmission? Think that more frequent changes would have made a difference??
