[DIY] Mercedes Benz GLA45 / CLA45 Transmission Fluid and Filter Change

[@jlow4544]

You hit it off the park!!! Thank you for this video. This is what I've been trying to find to do my TOC on my '16 & '19 (when it comes due). MB was going to charge me close to $600, but I can get the kit online for ~$250. Nothing like doing it yourself and knowing that you did it right, carefully taking your time, and not skipping any steps. Again, great DIY video!

[@jlow4544]

I was able to find out this information from my local dealership, parts dept. in Colorado Springs. They are awesome when it comes to supporting customers that are doing DIYs. Come to find out, I have a transmission type 724.016, with a 156.952 chasis, and 133 engine. All I had to do was provide my Vin#.

​@@jlow4544 Follow up: I was able to do this job this weekend. Took me 5hrs. 1hr wasted debating how to lift the car. A few things to note: - The electrical connectors attached on the right side of the airbox can be detached using a small flat screw driver. -- The smaller for the connectors has a small metal clip that slips out using said screwdriver -- The larger of the connectors has a plastic tab in the middle of the top of the clip that can be pushed away from you and the connector pulled from underneath -- The connector attached to the air inlet requires patience and a pick tool. It is one of those German double clip, clip :/ - A "Fine Tooth Ratchet" is almost a MUST. There is very little space to work the torx screws, so getting one (1/4") would be a wise investment - Note: when you measure the oil level, do it while the engine is running. Here's why: -- Before I changed the fluid, I check the oil level and it was in the 8s and 9s. -- I watched the other video with the mute German and he checks the level with the engine running -- While engine was running, prior to changing the oil, my reading went to 4s - Total amount of oil at the end of the day was around 5.5 "LITERS" of Liqui Molly 8100 - I bought the kit from FCP for $250 (tax/shipping incl'd); MB dealership was going to charge me $1200 and didn't even know about the "Additive" -- The transmission oil additive that you have to use if this is the first 2 time you do this job is NOT included in the FCP kit. It costs $70 at dealership -- This additive is an anti-foaming solution. And when used, you have to put a white (I used red) dot on the fill cap. - And probably the MOST IMPORTANT advise doing this job is: HAVING A SECOND SET OF HANDS MAKES IT EASIER TO REMOVE THE PAN -- One set of hands from underneath and the second set of hands from above pulling the top toward the front of the vehicle to clear all the hoses, etc. -- Removing the apparatus (don't know what it is, but is held in place by 3 inverse torx) will also make extracting the pan easier. I hope this helps.

The obvious question: Where'd you get the workshop manual? That would be super helpful in doing this job :)

[@ezquielsantos1760]

Have you learned where to find it ?

[@teddyandresjr6467]

Very informative. I just hope you put some links where did you bought the following: - Motul DCTF - Transmission filter kit - Dip stick - Anti foaming Thank you

[@nornibres]

Great video. I had to change the battery on my GLA45 one fine January day at -25 celcius. I have no idea how Mercedes got the battery in the tray as it was so tight. I ended up putting in an Optima yellow top as it was physically shorter than the original Mercedes battery. I see you have an after market battery as well. Changing a battery should be easy peasy. I watched your video and thought 'That doesn't look too bad,' but after the battery debacle I think I'll just take the car to Mercedes for this service. :)

[@muhdikhwan2007]

bro, can you send me the workshop manual ? by the way it's nice that you share how to do it with other people

[@alsajfl0288]

I really enjoyed the video.

[@ac9812]

I use to be a mechanic. I work on my own car's. My suggestions is if you got spare time to play with it is not a hard job. It took me total of 3.5 hr including tuning and reset. Dealership quote me about 860AUD I brought all the parts for 648. Not included a 14mm hex and a dipstick 😮

[@DJ170]

How to find the exact transmission number ? I have a CLA 2015, is there only one model?

[@Xyleksoll]

The oil pan is tightened at 8 nm. The 30 nm is for the drain plug.

[@markadams3746]

Great video

[@almanu04]

Thanks for the upload! Where did you get your instruction manual? Did you put the magnet back to the filter?

[@randomcar2190]

Let's just say you can get MB workshop manuals on certain auction websites with sketchy sellers. ;) The only magnet I'm aware of is the drain plug. I just cleaned off the magnet.

[@jorgetrejos9912]

Hi man. Let me respond your question. All data or Michel or WIS Last one is the one we use at Mercedes dealer the other two is the ones private shops use for manual repairs. For the other guy asking if you have to run your engine on for temperature yes you have to. Nice video as well to the owner of the video. Sharing info and media for many Mercedes lovers out there. Cheers

[@Marcesko]

So no issues with gearbox after this service? The WIS manual says it needs to be connected to xentry to execute some procedures to the gearbox, like "rev up" and "purge" to purge air from the gearbox.

[@CAsTiLL0_x]

So do you need to do this ?

[@brianmcelarney5489]

You should have disconnected both batteries before disconnecting the engine electrical to prevent an electrical surge through the ECU

[@aleksaleks93]

Where'd you get the workshop manual?

[@soroushfirouzi3572]

19:10 In this time that you were filling, how did you know the gearbox model ? How can i find mine?

[@AEMBowers]

Hi There! Are you by any chance located in the Bay Area, CA?

[@apexperformance1521]

What Gearbox oil can we use ? I see you are using Motul. any other DSG oil that is acceptable?

[@randomcar2190]

This is a tricky one to figure out, because MB made it into some complex puzzle to figure out which one is the right one for your car.... For my car, I needed the 236.21 fluid, so I googled it and a handful popped up. Then just dug around to see if any of the fluid makers says 236.21 on their spec sheets and what not. I don't remember other brands that popped up, so it was the Motul DCT and the overpriced OEM. Definitely, do your own research as to which fluid is the correct one for your car. Otherwise, the sure fire one to go with is the one at the stealership! ;)

[@uniforgiven12]

Great job! After filling oil is it necessary to use a new cap and/or lock pin ? Thanks

[@randomcar2190]

Yes, the lock ends up breaking when you remove the cap. You can find them on Amazon.

[@HAWX4]

​@RandomCar Do you happen to have an Amazon link, or the part number? I'm having trouble finding it.

[@DJ170]

What is the link or part number for the dip stick ?

[@tommyho6437]

Where do u check the temperature of the transmission fluid? Is it built in data or do I need a odb reader? If it does which do u recommend ?

[@randomcar2190]

You can check through the instrument cluster. Just switch it to the AMG menu and check the temp.

[@fahrvergnuugen]

Use an IR thermometer on the transmission pan. It gives a totally different reading than the gauge cluster.

[@benleach2055]

Where did you get the procedure documents??

[@asp1345]

Did you do any software resets?

[@randomcar2190]

I didn't do any resets, except for the service reminder. There is supposedly a learning reset (google it), but I don't notice a difference when I perform it. If there is any other transmission reset, I probably don't have the right 'computer' to perform it. Otherwise, my transmission is driving the same.

[@thereferee5547]

Genuine question how do you know how far you’re going down on the dip stick? Just as it doesn’t look like you put it all the way in? Thank you

[@randomcar2190]

Correct... youw will hit the bottom of the pan with the measurement stick. It measure how much fluid you have from the bottom.

[@mikehawk120]

Any difference for the 8G?

[@tommyho6437]

Do u really have to replace those gasket?? Can I just replace the fluid?

[@randomcar2190]

You could probably reuse the gasket, but it is best practice to change it. These are probably considered consumable items, and the service instructions says to replace.

[@tommyho6437]

@@randomcar2190 how much does all the part cost u?

[@randomcar2190]

@@tommyho6437 It was a little over $100 for the gaskets and filters and another $150 for the fluids.

[@rthavisin7819]

While measuring fluid level,is it necessary to run the engine?

[@randomcar2190]

Yes

[@rthavisin7819]

@@randomcar2190 thanks

[@fahrvergnuugen]

Do you check the level with the car idling or off?

[@randomcar2190]

I checked with the car off.

[@fahrvergnuugen]

I got confirmation that it has to be done with the engine running. The level drops a significant amount when the fluid is being pumped, so if you did the level with the engine off you are missing close to a half liter of fluid.

[@randomcar2190]

Dang! Thanks for letting me know. Time to go check the level again!

[@Kb_kevin]

Where do you get your parts?

[@elonmusk8667]

FCP Euro

[@DJ170]

You don't fill it from the drain plug ??

[@elonmusk8667]

Not this model

It would be almost, almost impossible.

[@Icarus_Ridexx]

I just purchased a gla 45 used and just opened the intake to inspect the filter. I noticed oil in the tube in the same place you showed. It's this normal or is it a sign that there is a problem?

[@randomcar2190]

It is normal for some oil in the intake. It's an emmisions thing, called PCV system. This keeps the oil from getting vented into the air and "recycled" back to the engine. But yeah... its normal for a bit of oil in there, but a lot of oil can be a sign of issues.

[@Icarus_Ridexx]

@@randomcar2190 It's not pooling and it looks dry so probably just normal buildup after 7 years and a lot of miles. Thank you for the response, it puts me at ease.
