Stickys suggest TC drain plug discontinued late 99, but nothing definitive. Trying to plan the fluid/filter change job for this weekend. Can any member tell by the VIN? Thanks in advance.

Just buy the 20 cent Aluminum Crush Washer, and have it on-hand, "Just In Case", you have the Drain Plug.

Torque converter drain plug disappeared in Sept. '99 I believe. That would mean that the '00 model years would not have it.

there is only one way to find out, get under the car and rotate the converter with a screwdriver (clockwise from front)

Update to original post

Hey guys
Went by dealer to pick up gasket $15 and Filter $16. Gave my vin to the parts guy (who is really nice). He said that I do have a TC screw plug w/ attached crush seal $7. Picked up a couple of plastic lock pins for the stick tube $1.5

He said that all 722.6 transmissions have the plug. (just reporting, I have no way of knowing if this is true)

He printed out a data card for my car that gave all the details and options - thought that was cool.

The MB Synthetic Trans Fluid is $20 a QT - Is that the best option. I'm not trying to be cheap - Just wanted your opinions.

Thanks for all the comments so far

My Method for Fluid replacement on the W210 with a 722.6

Mike,

Why only change about 70% to 80% of your fluid with a pan, and torque drain when you can get very near 100% of your fluid out?
No need to worry about draining the torque converter, washer, or aligning the engine to get the torque converter drain plug.

Do a fluid exchange!!

My method:

First, you'll need some supplies:

Fluid:

If you get the Shell ATF 134, the Valvoline Max life will do fine. You'll need to get FOUR-Gallons. Buy it in gallon jugs if you can, but you may need a few more quarts. The Max-Life fluid is 17 bucks a gallon from Walmart

You'll need to go to the home center and paint store.

one- NEW clear graduated one gallon paint bucket.

Six feet of 3/8" to 7/16" inside diameter clear vinyl tubing.

Make sure you have the Mercedes 722.6 measuring dipstick tool, and a NEW funnel for your 722.6, so no contamination occurs. Start fresh...

The process:

1) Drain the pan, replace the filter(save the old filter by the way-we will do something later with it), and replace the oil pan gasket. If you can measure how much fluid you drained out, so you can put the same amount in. It is about 3 to 4 quarts
2) Always inspect the transmission pan for debris, and particles; Then clean the pan.
3) Do not drain the torque converter. Just assume it does not have a drain plug.
4) Disconnect the top transmission cooler line from the radiator-A little fluid will drip. Be ready to clean-up the drips
5) Slip on the the clear tubing several inches into the flared cooler line.Make sure it is snug around the cooler line, so you do not make a mess
6) Lightly clamp so it is clamped to keep the tubing from moving out of the bucket, but not clamped to kink it! At the other end of the tubing to the rim of the paint bucket.Make sure the tubing is at lease half-way in the bucket, so you do not make mud pies once the fluid starts to come out.
7)Roll the drivers side window. Now start the car(leave it in park), get out an look at the bucket as it reaches the 2 liter or 2 quart mark(that's why you want a translucent bucket, so you see it from the outside). I will take 20 to 30 seconds to get to the 2liter or 2 quart mark. Stop the engine!! If you went over or under by little no big deal. Just do not go over the 4 liters, you do not want to run out of fluid in the pan. Keep it safe, and just empty out two quarts at a time. Use the dip stick tool every so often.
8) Make note of how much oil came out, and put the same amount back in OF NEW FLUID through the dip-stick tube with a new the new funnel, because used funnel for motor oil can destroy the o-rings in your transmission, just get a new one.
9) Pour out the old fluid into a recycling container.
10) Repeat step 7 trough 9 You will see new RED fluid come out at about three-gallons, but exchange out two to four quarts to get all of it out. Measure your fluid with the Mercedes measuring dip stick, so you do not over fill it.
11) On the last time, screw in the cooler line to the cooler, and disconnect the hose. Add oil get the dip-stick measurement close to the cold measurement side. Remember the oil is measured with engine on, and warmed-up. Save several quarts, so you can add a once you drive the car around.
12) You are done with the fluid change.
13) Now dissect your old filter like these 722.6 videos to see what your future will be like for your transmission.

FixEuro.com - European Transmission Specialists - Our YouTube Channel

You'll rest assured a little work will get the fluid from the transmission cooler lines, cooler, valve-body, torque converter, and every "nook and cranny"

I do this general process for all makes and models.

Hope this helps,


Martin

Report back on whether you really have the drain plug. I'm still guessing you do not.

On my car, I placed two small magnets on the inside bottom of the pan by its wall for clearance.

Anti-climatic update

Guys,
Got everything together - car up on ramps and stands - couldn't get the the plug out w/ 5mm inhex - stripped the plug - it wouldn't budge. Doesn't look like it had ever been touched. 2000 w/ 89K? anybody had this issue?

I'm kinda bummed - really wanted to get this done this weekend. Now I feel like I need to wait till tuesday, get it on a lift , and let someone w/ more experience get the plug out. (I'm on the floor with not alot of leverage).

Thought about
1. just dropping the pan and trying to manage the mess as best as possible. But that leaves me still having to wait till Tueday (holiday wknd) to get another plug from dealer - thinking local superstore not going to carry it. OR,

2. Do the DIY Sticky transmission line fluid replacement without dropping the pan - but seems like I'll be running alot of expensive MB fluid through a dirty pan and filter.

Any thoughts . . .

Find a torque converter drain plug?

I'd sure not do a half assed job. Better to wait and do it right in spite of your anxiousness. Can't break the drain plug loose with a little breaker pipe of some kind on the Allen? You can try dropping the pan, maybe tipping it a bit to catch the flow? Good chance it will still make a mess though. If you do it this way, you can always wait until the next transmission service to address the plug.

Mr. Sokolof,
Good advice. I checked myself on the anxiousness and parked the 320 and pulled out the Jaguar to play with for the evening. Agreed on the half-assed nature of my second thought! Have not looked for the TQ plug yet, but will and will report back.

Tipping the pan just seems likely to produce the mess I wan't to avoid, so will probably hold off until I address the plug this week. Thanks for the advice.

Mike,

You can actually tip the pan, and not spill a drop. I did the job on my Mother-in-Law's, and not a drop on her floor. I, too, had only front ramps available there.

If you keep the FRONT 2 bolts in place, and remove the others, you can slooooowly loosen One of the two bolts, and the pan will start tilting down, and to one side. Slowly alternate loosening the two bolts to progressively tilt the pan until there is a sufficiently low volume remaining, that you can flatten out the pan, and remove.

You then could try more aggressively removing the Drain Plug. If the inhex is too FUBAR'd, then you could use a Dremmel to cut a "groove" which you could put a large screwdriver on it.

If all else fails, you could try with a pair of vice grips.

Did you end up HAVING a T/C Plug??

:DCouldn't wait . . .

Went to Lowes and bought a large water heater drain pan ($20); bout 32" diameter. Followed advice on tipping the pan with the front two bolts intact and slowly worked them out - rmoved the pan with no mess.

Fluid was not bad - still had red color, but mostly brown. did not smell burnt.

No metal in pan, no sludge. I was actually surprised with near 90 k on the car.

I bought 1/2 inch tubing, and it was a pain getting on the upper trans cooler line. Had to flare it with needle nose pliers and 3/8 drive extension.

Once tube was on, had son fire the car up - ran fluid out two Litres at a time - replaced w/ MB fluid - repeated through 12 qt case.

No leaks! Glad that I know the condition of the fluid/pan/filter now.

Pulled the electrical plug - was moist - need to get one tuesday at the dealer

Thanks for all the advice, and comments. Plan on putting this at a 40K interval

Didn't see the TC Screw - But didn't spin TC - will try to remember tomorrow.

For future I would still recommend finding the plug as much more efficient and cheaper way to flush the transmission.
I had a Ford with ATF contaminated with coolant, what gave it milky color easy to tell. With no plug, I used the power flush like above. The system on Ford has 16 quarts capacity, I put 20 and it was still coming out milky. Even with cheaper ATF on Ford, that still dents your wallet.
When you have a plug, open it and let it drip overnight. This way you will have really high % of old fluid replaced.
