Mercedes-Benz W203 C280 Transmission Service DIY (Mercedes 722.6 Transmission Fluid Change)

►Like your engine, your Mercedes' transmission needs proper oil changes to perform reliably for years to come. Replacing the fluid in a 722.6 transmission, Mercedes' 5-speed automatic used for nearly two decades, is a straightforward job you can do at home with the right fluid and a few tools. Failing to replace the fluid at specified intervals will lead to rough shifting, hesitation, and even slipping under power.
Follow along as Kyle Bascombe, FCP Euro's Mercedes Catalog Manager, takes you through the flush and fill process on a Mercedes W203 C280 4Matic 722.6 automatic transmission.

Best tutorial in KZbin! Very well explained step by step!

[@28761d]

Amazing tutorial. Attention to details, well-explained, and very clear👏👏👏

[@mr_sparkly_face4087]

Thanks guys! Just changed my C32’s fluid and did the trans connector while i was at it, super easy maintenance for a super sedan

[@cutlasssupreme508]

This was so Good. So thorough... Beautiful teaching...

[@rjkulman8990]

very thorough and straight forward explanation, tks

[@RothBeyondTheGrave]

Along with the ease of service, you also get a much higher capacity to handle torque? Remind me why I should keep my 722.9 again?! It's still a nice gearbox....keep 'em comin' Kyle! I owe a large part of my Mercedes ownership to you & fcp!

[@TheDomin8rr]

My indie told me the blue ATF MB uses in 722.9 is backwards compatible with 722.6 & runs cooler than the red 184. Isn't it recommended to swap out valve body pilot bushing whenever dropping the pan?

[@erickalemwa7832]

Thank you

[@philipstreechon4523]

Hi grate video would my 2014 Mrecedes-Benz glk350 4MATIC transmission be the same process?

[@a.ca.c9809]

Great video..i wish you lived near Santa cruz..having trouble with my c230 kompreser 2005...limp mode

[@fcpeuro]

Sorry to hear that!

[@djlouis2150]

How many transmission fluid that it takes I have a mercedes clk 320c???

[@jessecloete2388]

Hi there Hi there i have a 2003 W211 E320 petrol. Its the one that has the trans cooler built in to the radiator. Unfortunately that failed and my coolant mixed both in the radiator and trans. My car doesnt have the torque converter drain and I dont have the tool you recommended Firstly how many flushes would you recommend for the transmission especially if i cant get the torque converter drained? Secondly would you recommend only installing the new transmission filter once I have flushed everything I wanted to order from FCP Euro as you literally have everything I need and I know its a guaranteed fit, but the shipping costs quite a bit more than my order because I am in South Africa

[@mohitmudgill7757]

Can I use the air pressure tool for my E300/2013 model

[@28761d]

Was it liquimoly that was in it before the service?

[@SonikDethmonkey]

How far down do you push the dip stick? Literally all the way down until it doesn’t go anymore? Or when you feel resistance right before the bottom?

[@fcpeuro]

Hi Sonik, you feed the dipstick in until you feel it bottom out in the sump.

[@IPTQ81UR]

You recommend using the CTA 7650 tool when you don't have a torque converter drain. If you do have a torque converter drain would it be overkill to both use the 7650 and drain the torque converter?

[@fcpeuro]

Not a bad idea, as the CTA tool will ensure that you're pushing old fluid through the valve body and additional capillaries! Just make sure you do the due diligence on your refill and "bleed" procedure by cycling gears, driving, and checking fluid level frequently as of course, you'll be completely draining the system.

[@machanickarz4805]

Sir C 200 kompressor how much fluid fill in automatic transmission

[@mariokajin]

Didn’t you forgot one fastener near the filter hole?

[@jovanzacevski]

Hi, I have problem with ny 329 CDI 4 matic. When cold there is between 1200-1800 rpm like clutch engaging and disengaging feeling. After third gear it is ok. When engine and i think transmission is hot then gearbox is like 99% new. What could bw thw problem ?

[@markkrauss7922]

Does this have a conductor plate?

[@ricardosantos9960]

Can you fill the auto trans on a 2011 w219 from the top as well?

[@bigqwertycat]

Yes, the w219 is basically the same as a w221. Just slightly different body.

[@youremadstinky5623]

How about a 2007 C230??I can’t seem to find the tap

[@ervindajlani451]

how are you master, I have a Merceder w203 diesel c220 year 2006 Automatic when I start the car in the morning, it gives me a little knock in the gear light until it warms up, then it doesn't go on, what could be wrong

[@gabrielc5642]

Gearbox mounting

[@BiggECheez]

Why not pop the engine cover off so you can see what you’re doing when adding fluid? It takes like 10 seconds

[@hmax97]

Dipstick measurement when the car is off?

[@fcpeuro]

Hi hmax97! Check out our other video "How to Check Mercedes Automatic Transmission Fluid Level for 722.6" with Kyle if you're still uncertain!

[@petersoong3800]

How many liters of gear oil, used for model 203?

[@garyzhang5099]

depend on how much you can drain out. There will always some old fluid inside the torque convertor. If you left it drain overnight, you could get a bit more out.

[@GETCHABEATS]

Dealer wants 1500 to do this thank you

[@ProjectArjun]

Why is he wearing a winter coat? Something tells me this video was recorded in February 2022

[@bi7259]

Or he's promoting their merch!

[@haus_of_wisdom]

That doesn't matter. What matters is the good job he's teaching

[@tombanes]

Such detail but no detail on the proper fill level. You have to use the tool and it has to correspond with the trans temperature. You have a range of 10 mm on the dipstick in which the trans will be considered properly filled. EACH mm on the dipstick equates to only 1 oz so it is very easy to overfill the transmission. My transmission when hot is about 165 deg F so proper fill will be 65 mm on the dipstick tool with a range from 60 -70 mm . If you dump another 1/2 liter (16 oz) after that you are way overfilling.

[@adrianstoian5418]

Big fail,engine must be at idle to check gearbox oil level, all well done untill this point.

[@bergrud]

Listen. It is.

[@stephenperrone8694]

It's not a good idea to clean the interior of the pan with either cloth or paper towels. Residual fibers can cause transmission passageways to clog. Even checking the fuid via dipstick, Mercedes recommends using a leather cloth only. Better to clean the pan with a solvent like gasoline or alcohol then blow it dry never using any cloth at all.

I love a good zipper on my paint job
