To use this dipstick correctly you need to get ATF temperature to 80deg C. So you need to measure temperature. I used infrared thermometer pointed at the pan.
Also, if you torgue converter has a drain plug you need a new seal washer for it. And you need something to turn engine to get this plug in the position. In my engine (M113) 17 mm hex. I found that the lug bolt for my winter set is perfect for that. It has hex long enough to get it into the engine and use 17 mm open wrench on the other side.

Torque converter plug was deleted as of 9/22/99; as of transmission #1772285

Add a torque wrench and you need torque spec. On my 94 E320 the pan bolt spec is 8NM, I think. Any body know spec on a 2000 E320?

Use a lintless cloth to clean pan. Pan must be clean clean clean. Some use a chammis (spelling?), you know lambs skin. But I tried a few different rags, until I found an old sweatshirt that did not leave ANY lint.

Also, I recommend cleaning the threads of the bolts with a wire brush. Just enough to wipe away the corrosion. The bolt will go back in much smoother.

On a 2000, I am relatively sure you will NOT find a drain plug on the torque converter any longer. About the time they started the Touch Shift is when the drain was gone on the TC.

For cleaning the pan, the bast way to go is to use solvent, then dry with compressed air. DON'T use any type of rag or chamois to dry it. Use paper if neccesary. The shift valves can cut paper fibers, but not fibers like cotton or wool (or sheep skin). Best is compressed air.

On a 722.6, the pan bolts are still torqued to 8nm, the drain plug is torqued to 14nm.

To allow the bolts to screw in better, I run a tap through the bolt holes in the case.

Drain Plug on the torque converter

Hello Gillybenztech.

Would like to ask you a question. Like you said the E320 model 2000 does not have the drain plug on the torque converter. Is that right. Please help. That mean I just drain out the old fluid. Take out the pan and filter. Put the new one on then refill the new fluid. Check the ATF with AT dipstick.. That it.

Please let me know..

Thanks

The transmission fluid is filled for life. You shouldn't change the transmission fluid. For life it is filled now. For the fluid to be changed now it is to be at the end of it's life. For the plug in the transmission filter to be pulled would be a mistake. My God, it is only a model year 2000, do not to do it. To bring much joyful service i would leave now the transmission fluid from Germany installed, not to replace.

gillybenztech, Why is everyone telling us to change the fluid at 60k or so on these new transmissions to keep them going for the long haul??

Yes it is synthetic and filled for life, do not change the fluid.
I have no real good idea why this is being recommended.
If you really plan on keeping the car for a very long time(say 10 years) then maybe do replace it. I wouldn't really recommend it though. These transmissions are good for several hundred thousand miles. Those that have failed I don't believe would have been saved by replacing the fluid.
I worked on a 99 E300 TurboDiesel today with 210,000 miles on it which has never had any service work done on the transmission, and a service advisor at work has a 97 E300 Diesel with 280,000 miles on it which also has not had the transmission fluid changed.

How many miles do you have on the car? It is a 2000 E320 correct? Is it stilll under warrantee?
I thought I read in the Mercedes Club magazine that Mercedes has sealed the transmission and if you open it it voids the warantee. Please check with Mercedes before doing this.
Mercedes found that 90% of transmission problems were improper servicing. the felt it would be better if they could just keep untrained mechanics out of them they would lst longer.
But of course it is your car, Do as you please. I would hate to have you void your warrantee by doing this.
Of course youmay be way over the warrentee.
