- Today we're exploring more of the transmission on my mechanic special 335i, and we replace all the seals under the mechatronics unit! Hopefully this helps resolve the weird transmission surge issue we're experiencing, let me know if you've felt this on your BMW before! Maybe its just a sign to do a manual swap... ;)

Thanks for the great detail you put in to the video. I had my 4 rubber sleeves out for a while till I got to it later. I forgot the sequence to put it back to gether. After searching days, I came across your video and saved me a lot of trouble. Thank you again.
I always have good luck with Valvoline MaxLife ATF. I used it in all my four BMW vehicles and they shift better than high end fluids.
i have heard from ppl that either oil change or replacement of torque converter will help that up and down reving, my brother had that problem on his e61 535d but oil change did help with that problem and i have seen ppl having that problem and need to change torque converter.
Hi Chris. Reset the adaptations and drive the car for a few days in different circumstances. You have to give it some time. Dutch regards, Nico.
I used to have that issue too, but I reset it and drive normal for awhile once it learn the driving style it shifts perfectly.
That's what I'm hoping happens! Will definitely update in a future video on the matter.
I bought a mechtronics maintenance kit. But my cylinder rubber seals look different then these. They don’t have any contour or lip like these have. They just like angle cut.
hi, my 335i with the n55 jerks/hits hard from 3rd to 2nd gear, engine is tuned with MHD and transmission is tuned with xHP, any idea whats going on? its super annoying
Thanks Chris, the AUC sensor arrived yesterday.
Awesome! Time to install and clear that fault code! :)
@@TheBimmerBarn DONE! for first time since i have owned the X5 it has no fault codes
Im having a problem with my 08 bmw 335i were its shifting all the gears between 1500 rpm and 2000 rpm? Is that normal? Also each gear has a hard kick too it was told it had a transmission tune
Is this the same procedure for the GM 6L45 and 6L50 transmissions?
Hi, wobling RPMs while steady drive means that your torque converter is bad... btw: when you want to "readapt" the TCU for new values, you need to reset the adaptations with diagnostic device.
Hey I got my transmission rebuilt on my 2008 335i bmw but wend I put it in drive it turns off do you know what is the cost of that
Did you use the ZF fluid? I have a kit with the liquid molly fluid for this transmission. But I was just wondering if the liquid molly was just as good?
I like liqui-moly, and their fluids are equivalent or better than the BMW oe stuff. They're both approved to the same standards.
My 6hp19 gearbox has 50k miles on it and it fluctuates in rpm when shifting from 3rd to 4th gear and throws the 4F89 error. I changed the sealing sleeve, oil and filter, I will analyze the solenoids.
I did a lot of research on this error code (4F89) and came to the conclusion that the problem is not with the gearbox itself, do you have any idea what else I can check?
If the code is persisting, your options are to check/replace the solenoids, and then after that, possibly replacing the whole valve body or transmission. Sorry about the trouble, good luck finding a solution, and write back when you do!
@@TheBimmerBarn Thank you so much for replying and trying to help me.
The mechanics will be removed for a complete cleaning and analysis of the solenoids.
Did your car ever kinda stick in to 1st or 2nd and flare the revs when the cars still a bit cold? I think I have the same thing your car has in my 08 335i so wanna check if we actually have the same problem before I got messing with my transmission
Yooooo
Thank You, Great videos...2009 328i showing these 3 transmission codes? I'm very scared...is there any hope or is this the end?
-56B8 (EGS ratio fault R)
-56BF Clutch gears 1,2,3,4 neutral test
-56BB Clutch gears 1,4,5,6 and R neutral test
Maybe someone else can chime in too, but it may be worth changing the solenoids in the transmission, along with these seals. At the same time, its not too expensive to source a used auto transmission, so that would be your next best bet. Best of luck friend, thanks for watching!
congrats on the 1k man, I just found your channel today after watching some other videos on some issues i was having. I do have an issue with my 140k 2007 335i. I wanted to send you a video if possible or find a way to contact you. This issue has been plaguing me for so damn long. I think it's trans-related but I'm not sure. I have checked far and wide and not a single video on youtube showcases the issue or possible fixes. In fact, my local BMW mechanic has not a single idea of what it can be ;/ You said "surging", a bit more detail would be nice but i assume it's what's happening to me. During higher gears at around maybe 1400-2100rpm, I get an oscillation. My RPMs are jumping up and down nonstop. But when i get up and moving or am in lower gears, it's not really there much. It's so aggravating. It keeps jerking me forward and back nonstop and my RPMs just bounce up and down.
edit: i uploaded a small clip. I couldn't catch it being very naughty the day I took the video but, the RPMs are far more erratic at times and jerkiness can be horrible. th-cam.com/video/jlQm4Erzek0/w-d-xo.html
Poop, "oscillating" would probably be a better term for what I am/was experiencing. After replacing all the seals, fluids, filter, and doing a transmission adaptation reset, I'm happy to report that the oscillation is less noticeable, and continues to fade away with more driving. Other people here have recommended a transmission tune which would increase clutch pressures which may also help alleviate the issue. My transmission doesn't throw any codes, so I have no reason to start replacing expensive solenoids.
Hopefully the video and my experience helped you, and I wish you good luck with servicing your car! Let me know if you have any other questions :)
@@TheBimmerBarn Your the best, thank you! I guess when i buy my 3 last index 12 injectors, i will go straight to dealing with the transmission. But if i can ask, is the video i provided the issue you were also happening?
@@N54.S6 Yes, exactly the same issue except yours is much worse if I'm being honest. I'd do the transmission seals and filter ASAP if I were you. Good luck :)
Good job Ray , question where did you buy that car jack and do you like it
I got the Quickjack from Home Depot when it was on black Friday sale. Best price. I really do like it! Use it every day almost. I have a video doing a review on my channel, you should check it out!
Has anyone tried the ebay seals yet? I’m on a tight budget so was wondering if it’s worth it or should I just get oem.
how do you reset the transmission??
Mine is done same thing. 138k miles. I got liquid moly fluid , sleeves & seals. And a new pan. Hope it solves my issue. Good informant video the music was a little loud during the bee row kind of threw me off. That’s probably because I like working on the car is in silence with no music on so I can hear and see everything, I’m weird like that
Was it solved?
Any updates on that did everything work out
Do you have yours tuned?
Hi
I have an e92 m3 and I was having problems with my transmission.
The car would struggle in reverse and also getting into gear one.
I’ve changed the oil and filter completely but that hasn’t resolved the issue.
Would you suggest in replacing the Mechatronics?
The M3 has a DCT transmission, very different from these auto's that use a torque converter. I'd recommend taking it to a specialist or the dealer for a full diagnostic! Sorry, hope that helps
@@TheBimmerBarn thanks for getting back to me 👍🏽
I did the same thing. Changed fluid and pan it’s better but still funky between 2nd and 3d and some lurching. So back under and change seals and I’ll try not to make such a big mess this time 😅
Does that cylindrical sleeve just pull out? Does the trans need to be opened to replace it?
You need to at least drop the pan. There is a pull down lever that holds the sleeve in place. Once you replace the sleeve, you push the lever back up to lock the sleeve
Awesome video except the hardest seal the last one you didn’t give any advice this thing is a pain😅
I like how he doesn’t show how much he probably struggled with that mechatronics sleeve. Or is it just me 😩
Me too 😭
Dude how did you get it in . I have been struggling for about 2 days trying to get it to sit flush with the 2nd O ring on the sleeve …… HELP lol
@@392SCATBLK I pretty much found a washer that was just a tad bit larger in diameter then the sleeve itself. I then used a few long extensions and a large socket like a 22mm I believe and then was able to press that against the sleeve with a hammer using leverage against the exhaust piping. It went in quite easy. Just make sure you Vaseline the seal pretty good. I absolutely was not able to do it just using my hand with force.
@@luispina317 thanks for the tip bro , I was trying to force it in with zero lubricant , absolutely impossible lol 😂 thanks again
Hello great videos - mmm on my case it only hard kicks 2nd to 3rd - and when manually doing the gear change while releasing accelerator pedal or going downhill it feels normal - also no codes on computer - . What would be your advice where to start looking before jumping straight ahead into buying a full valve body ?
Have you replaced the fluid and pan? After doing that XHP is great at smoothing the trans also.
Would I have to drop the pan to do the seal that connects to the harness?!!!
Yes, you have to disengage the lock from inside the transmission, it's the only way
Where do recommend we get the seals/gaskets ? I’m definitely thinking of getting the service kit from fcp euro ✊🏽
Yeah I use FCP euro as well, fair prices and lifetime warranty baby!
@@TheBimmerBarn they have the transmission gaskets ? If so what do we search lol bc I can’t see it
Part numbers added to the description! :)
@@TheBimmerBarn thanks a lot man, that was super helpful. I called my bmw dealer and they told me according to my VIN my transmission was GA6HP19Z so I’ll order these parts and hopefully it helps fix the issue. If not like you said just do a tranny swap 😆✊🏽
@@BassFraud Yeah! It didn't make a huge difference at first, but my buddy has been driving this car for months and it's literally gone away completely! Just took time to work itself out. Good luck!
You should have made a video of the surge bro
Does the 335d have the same transmission?
There may be some similarities in servicing the two, but the Diesels use a different bell housing and transmission, so the part numbers for the filter (for example) will be different. Good luck :)
What torque
Will be much better with reset and XHP flashed
Definitely going to look into this!
Trans mount is missing the bolts
Those were removed to let the transmission sag down so to get better access to the seals and the harness! Gives you that extra bit of room, but don't forget to reinstall before you start the fluid fill procedure 👍
@@TheBimmerBarn good to know I’m about to service my trans
next time dont dont kip over the connector
Yassssss twerk them bolts down lol 😂 so thankful for this video!!!!!! Thanks
Happy to help!
