Dealer charges $260 for Transmission fluid service. Should I have it done myself or it's worth it for them to do it?

Any comments would be appreciated. Thanks.

DIY advantage, you know it's done correctly.
$260 would only be partial like 4 quarts, as most of the fluid is trapped in the Torque converter and no drain plug. Capacity is about 9 quarts, but it takes 13 to do a full flush, some goes to waste.

Search for my thread on 722.6 DIY
Never mind here it is

AND I found this pdf elsewhere but it's just the drain and fill.
Nice pics though. Attached.

Order the Fuchs compatible fluid from rmeuropean dot com
Get a connector with orings from a dealer for about 7 bucks
and use MB filter and gasket.
You'll need orings for the cooling hose to the radiator, if you do the full flush and a crush washer for the pan,
something i forgot.

Easy as cakeee =) just make sure you tq the bolts for the pan correctly. There is also an order to tighten them in. If you don't have the dipstick don't even try this

I suggest 1st you update your profile with the YEAR of your C230, so we make sure you get the right information.

Todd, aka C230 Sport Coup spoonfed you the information for the 722.6 which covers up to model year 2005. 2006-2007 C230's (non-4matic equipped) have the 722.9 transmission.

It's 2006 C230. I really like to start doing these myself unless some major works that need to be done at the dealership. All your inputs are greatly appreciated.

Oh by the way, my local German Auto Indys charges about the same amount. How stupid is that?

Yours is a 722.9, equipped with a torque converter drain plug. There’s nothing to it.

You’ve had occasion to read johnand’s excellent DIY, yes?

Where is JOHNAND's DYI please? I only see "C230 Sport Coup" posts. Thanks

Lucky you, the closest dealer to me charges $550 for the tranny service..although they also told me its a 1 time service at 39k miles and that's its for the entire lifetime of the vehicle...

It's amazing. After Johnands excellent DIY we have the W204 guys doing their own tranny services. Only RLE thinks it's too difficult. So he can keep the stealers kids in college

I used the same DIY on a GL450 and it was not too bad. I used an IR thermometer as a SDS is well outside my reach for the fluid measurement.

There are a couple of additional bolts to remove which secure a wiring harness compared to the w203, but you can use the air suspension to raise the car instead of jacking it up which saved time. MAKE SURE YOU STILL PUT STANDS under the car just incase!

Is the AT flush the same process as the manual tranny? I have the 6 spd in the 06 c230 and am wondering if I should follow this same DIY or not.

eesjunin

just found out $400 for tranny flush, even though by mistake they charged me only $200 a few years back... Would this be somewhat in the vicinity what i might have to do on my C320? Thanks!

same question on the manual...i have an '05 (is the differential fluid just as easy to change as well? just drain and refill?

pcy

differential fluid change is very easy. Loosen the fill plug, remove the drain plug, put back the drain plug, pour new fluid until it runs out, put back the fill plug. Done.

Trans fluid change is also not bad if you are just dropping the pan, replacing the filter and pouring new fluid. If you are doing the trans FLUSH, more work involved, more fluid is involved.

eesjunin, when I need to get under the car to work (like changing the trans fluid), I go to a place called 'U do it yourself' in Nashua (near Nashua library). They charge $30 per hour to use 1 bay (that includes the lift and all the tools in that garage). I plan for several things to do with all the parts ready and plan it nicely to use the least amount of time on the hoist/lift.

I was told that manual transmission don't have a filter or gaskets etc...

C230 Mulac

that do it yourself thing is nice, i wonder if there's anything like that around DC, i would definitely use it

samaritrey

Yes there is but I can't find the link for you will keep looking

C230 Mulac

i assume you came back and edited the post to add the link, thanks man, i'll definitely check that place out!

droco

I'm gonna attemp and do this... Hopefully i don't ruin my tranny.

So far MBworld has been amazing for DIY

droco

Yeah I have a 2005 C230 1.8L, just looking to make sure of the type of fluids. I plan on ordering all parts as well. The hell with the Stealership!

550 Cad for Flush

700 + for Brakes (Rotors and Pads) which i am going to change myself.

M.L.X.

thanks for the PDF!

looks easy. even if it costs the same as dealer, I'd rather do it myself just to make sure it's done right + good learning experience.

$260 isn't bad for a dealer. my local stealership wants $400+!!!

local indy charges $260 I believe.

anyway, just found a Navy station that sounds like they rent out lifts.

I'm gonna go check it out. need to replace my fuel filter too and putting the car on a lift would make my life alot easier...

hope it's not too expensive to rent the space... and they let me in since I'm not military.

eesjunin

Can someone shine a light on me with the above mentioned pdf and how that might be different with a FULL flush...are there some steps that are not mentioned?
Thanks!

droco

Yeah i know what you mean... Some pics are missing.. Even though they are great explanation and by no means could I do better.... For individuals not so mech. inclined.... and how ish always goes wrong for me.. I'd be stuck missing a tool lol...

Which pdf are you referencing?
A full flush, once the pan has been dropped, new filter put in and the 4 quarts replaced, requires disconnecting the fluid cooler hose and
pumping a couple quarts at a time, then replacing them till the fluid comes out clean.
A standard transmission service just invloves dropping the pan and leaving
5 of the 9 quarts of dirty fluid in the system.

If you read the thread I created and linked to in this thread, I believe I have the MB documentation describing both processes, but here on the forum the process has been slightly modified to accomodate us DIY'er.
Meaning, disconnecting at the rad vs. the bango bolts at the tranny.
Now if you have access to a lift the banjo bolts would make more sense, but they are very wierd connectors, you can't just put a tube on them.
You need a special connector I think to catch the fluid.
But same process applies, stopping and starting the engine, so that means
someone needs to be in the car while it's on the lift, OR putting the car up and down.

Read the whole thread and most of your questions will be answered.
Replace the connector while you are at it, with a new one with new O-rings too.

MB created the full flush doc as to be used when the tranny gets glycol contamination,
but uit has become obvious to most of us that a full flush is necessary, 4 out of 9 quarts and a new
filter doesn't do much when the fluid is cooked and oxidized.
You do really feel the difference.
I'm due again....

Woa, $5 shell ATF?
