Transmission service
I just bought a 1997 E320 with about 115k on it and I am taking care of a few things the car needs. I just replaced the plugs, plug wires, fuel filter, and dropped in a K&N air filter for only $90 and 30 min of my time-- I love inline motors. The car really seems to be running great, but I've noticed the 1-2 shift is a little harsh at times which is normal when cold, but it will even do it sometimes when it's up to operating temp. I know the tranny is in need of a fluid change and I am eager to do it. For some reason Mercedes had the 722.6 tranny "sealed" and I am curious how I should change it. I've read that it requires MB fluid and a special tool. Has anyone done this on there own? I am about to graduate from Georgia Tech with a Mechanical Engineering degree and it really hurts my pride and my wallet to pay anyone to do automotive work for me. I usually do all my own work on vehicles, and I've changed tranny fluid and replaced a few trannys on other cars so I know its not difficult. I just wondered if there was anyone who had done this on their own. Is there a write up on this or anything. I have yet to even take a look at the tranny so I'm wondering if I will find a drain plug or a fill plug like a normal trans. If anyone has any insight on the proper procedure, it would be greatly appreciated, if not I plan on doing a write up myself. No one should pay $250 for something that would only take about 15-30 minutes to do.
thanks in advance

1. Goto Merc dealer, purchase 7-8 litres of their ATF (depending on chassis number of car)
2. Buy pan gasket and filter
3. Buy gearbox dipstick

I'm not very good with that stuff so I had it done on my 1999 C. It does help that 1-2 shift that my car seemed to have as well. It seems that this flud change is the same as any other with the exception of its own dipstick.

Thanks a lot for the link, that is a great write-up. I will be changing my tranny fluid next weekend if I can get parts in time. Now the question is where to get the cheapest MB parts. Is Fastlane the cheapest or are there certain MB dealerships that have better prices. I work on a lot of 93-98 Twin Turbo Toyota Supras and I know that there are two Toyota dealerships in the U.S. that actually charge reasonable prices for parts--no huge markup. These dealers even advertise on Supraforums.com and they do a ton of parts business. I am curious if there is any MB dealers that operate like this, guess I'm about to wear out the old search button. Thanks again for the help.

It pays to shop around. I've found that for mercedes branded parts, the best places in terms of price are: ebay, Ben's workshop (downtown austin), and MB of Georgetown. MB of Austin will match georgetown's prices, but you have to ask (example transmission fluid = $8.00/L at Georgetown, ~$11.00/L at MB of austin).

I think you would be better off doing it through a dealer. It will be done right the first time and dont have to worry about anything. It will cost you around $200 dollars. Because the Synthetic oil is expensive on it. I just had replaced on my 1997 E420 at around 85k miles.
