me and a (he use to work for a local owned benz repair shop) buddy are going to change out the transmission filter if i receive tommarow.

how much transmission fluid do i need?
and is there any special type or brand of fluid that i need?
is there any special tools that i need to do this???
can i put any additives such as Lucas stop slip?
is there anything else i need to know before doing this?
:confused: :confused: :confused: :confused: :confused: :confused: :confused:
thanks in advance

Then you'd shell out good money for no reason, the purpose of this board is to learn how to operate on your vehicle in a successful manner. Because you are scared to get under it does not mean you need to make someone else feel the same way.

Changing the ATF is a VERY simple PM issue often overlooked that can result in costly repairs. It'd be quite foolhardy to simply "replace it" when it needs only a new filter, pan gasket, and ATF.

If you drain the converter (that should still be a four speed 722 with no OD) as well as the filter, I'd pick up two gallons of ATF. Fill it with five then check the level accordingly. For some reason I think the converter holds about four quarts.

I use cheapo ATF from McParts in all my vehicles and has worked fine for hundreds of thousands of miles with no ill effects. Some swear by Syn in the ATF, not me. I do not go for extended drain intervals there and I do not beat on the unit to warrant the higher heat capacity.

No need for additives, just keep it clean and change it often.

Only tools that would be smart to add to the arsenal at home would be an in-lbs torque wrench so you can torque those pan bolts properly. Aside from that you need a screwdriver, metric sockets, and such.

Good luck with the drain, it's very simple to do. :)

i should be receiving the filter and gasket it the next hour.

now im having thoughts of just taking it to the dealer for the change out and while its there run a diagonstic???

Not sure if I have the full story or not.... Is there a problem with the tranny? :confused:

tranny slipping i think???

is a dipstick tool required?

Are you saying you don't have a dipstick or you can't find it? Worst case - you could always measure what is drained out and replace the exact amount.

Have you tried searching on the fluid change procedure? It's been discussed before.

Hopefully your transmission is like mine. This is how I change the fluid....

The torque converter has a drain. You have to turn the torque converter until the drain plug is at the bottom. I believe a 5mm allen wrench removes the drain plug on the torque converter and pan. Drain both. You'll get about 7 quarts out of the transmission. Remove the pan, clean it, and replace the filter. I believe the pan gasket is reuseable. Button everything back up. Initially, pour only 4 quarts through the transmission fill/dipstick tube. Start the engine and let it idle. Pour in the remaining charge.

It's best to fill it short about 1/2 - 1 quart, then check the fluid level hot after a long ride and refill it to the proper level.

is there any certain brand or type of transmmison fluid that i need or can i just pick some up from any auto parts store???

i dont have a dipstick i will have to meassure the old oil the way you said. ho
i just checked out the diy for the 722.6 tranny (i dont know if its the same as mine).

what kind of fluid do i need???

thanks

My car is awaiting a fluid/filter change as well. When I inquired about this I was told that regular "Dextron/Mercon" will work fine. :confused: :confused:

so just something like some regular dextron 3 will do the job no synthehic or special mbz oil.

thanks

Seems as though.

Transmission Hydraulic Fluid
 

Given the expense and apparent failure rate of some MB transmissions, it might be worthwhile to consider using the recommended fluid. The dealer has it, or you can look at http://www.***************/
Some have suggested doing an analysis on the used fluid to check for internal deterioration.
Since dealers have a checkered reputation on how to care for these transmissions, it might be worthwhile taking your car to a recognized and reliable independent for the first fluid change to establish a baseline, then doing it yourself thereafter.

Dexron III - that's what's specified for my car and that's all I use.

Since when is a 1993 a late model unit? :confused: Last I checked that 722 was the same as the later W126s. I have well over 20000 miles on my SD's trans with cheapo ATF, about 5000 on the L's, 80000 on the Z, and about 25 on the Ford.

i was thinking about doing this tommarow but might hold on until monday.
i will keep everyone posted.

thanks for the replies.
