it under the passenger side air box. You need to take it off the airbox to be able to access it.

It also has a tamper proof cap on it. if you break it off, you'll probably need to get a new one from the dealer to seal it back up.

I have a 2003 c32 amg. My owners manual gives a list of acceptable transmission fluids. Someone told me we have a zf transmission and we can only use mercedes fluid. Is this true or are there other acceptable fluids and what specifically are they? Thanks.

TemjinX2

we do not have zf transmissions, your thinking early e46's. THe c32 transmission is produced in house by mercedes. Its preferable that you use oem, but others have used aftermarket without any real problems.

I changed mine last week. I got something like 3.25 liters with the drain plug removed and another 0.75 liters when I removed the pan.

I used Fuchs 4134 oil which is approved for the 722.9 transmissions and is backwards compatible with our 722.6. Not wanting to mess around with cooler lines I drained and refilled it twice to get more of the old oil out. Shifts are a lot smoother.

Has anybody used the castrol import multi vehicle fluid?

I highly suggest just using the right fluid. I mean really, how often do you change the transmission fluid?

mikekuriger

Not often enough I'm sure!

Most likely, I just serviced my trans at 36k miles! I still have some fluid left over so I may do a drain and fill next time I change the oil. Sent the fluid off to be analyzed so we'll see how she looks.

I did mine at 100k.

what if you drained the oil first?
is there a way to estimate how much transmission fluid to replace instead of buying a dipstick?

Measure the amount of oil you remove... What if it isn't at the correct level to begin with? You can get the dipstick online for less than $50 dollars.

Does anyone have a DIY instruction guide or anything on how to do this, I want to change mine very soon

I like how the flush was done on this thread. A lot easier than getting under the vehicle. I took the other route and pulled the cooler line off the torque converter... The start of this thread is a DIY write up? What else are you wondering?

c32kompressor

where is the drain plug located? mercedes told me you needed a certain key tool to do the tranny flush?
