The best video explaining why , most of the people don't know why the clutches are burning In Romania its asking 2300 euro but they dont do anythink inside mechatronics/valve body !!

[@legioner9]

This guy is spot on. I changed the solenoids, bridge adapter and those other 4 rubber tubes but never actually opened the valve body itself to change those little dampers inside and the plate. And guess what, after 1 year the gearbox has a small delay before it engages D or R.

[@JDMsohc]

Are you able to offer advice on an 8HP as well? My F30 335i is throwing a code, 420641, and it wont shift out of park. I already ran in ISTA diagnostic, which told me to replace the mechatronics. I swapped out the valve body and the EGS and virginized/coded it to my car, also replaced the mechatronic sleeve, the transmission pan, filter, and fluid. Yet my car still won't shift out of park. I can screw in the emergency neutral bolt on the side of the transmission and that will put it in neutral, but if that isn't screwed in and I get into the car and just try to put it into any gear, it automatically shifts back into park. Any advice would be greatly appreciated.

@@werkstatte-bmwonly9515 I’m interested in knowing more about which cars use isn locks and which don’t. Also anything you know about upgraded clutch packs, valve body’s, fluid or general upgraded parts. If they work, if they don’t etc. I would also like to know to interpret clutch pack adaptation numbers. What those numbers mean in terms of wear or what could be causing issues. Also basic guidelines for maintenance and preventative maintenance.

[@werkstatte-bmwonly9515]

So the earliest ISN I've seen would be on e70 X5. For example 2008 BMW 750i with 6HP26 can be installed and driven used without a problem. 2008 bmw X5 with the same transmission will have a problem with ISN and CAS match. All 8 HP transmissions are locked with ISN. We can reset them here. There is a also a trick to make a used transmission work but you would need a CAS module from the donor vehicle.

[@Dru26JC]

I have a 6hp26z and have already changed the fluid, seals, and filter. I didnt change solenoids or valve body. I did reset adaptions and drive very conservative for 200miles. However, im still slipping in 5th gear and going into limp mode. Only when beendrive a bit harder than regular, otherwise the car drives perfectly fine if kept under 3k rpms.

[@mcleanva2]

@werkstatte-bmwonly9515 --- I have a question (2008 750Li - ZF6HP26 - 102k miles). Is it necessary to "reset adaptations" after completing service on PAN/FILTER, LIFEGUARD 6 FLUID, VALVE BODY SEALING SLEEVES (5), and ADAPTOR PLUG? My car is running fine, this is just preventative maintenance. I have never replaced valve body plate, solenoids, or pressure dampers. In other words, if I simply complete a Mechatronic Service on sleeves and adaptor plug... with fresh BMW fluid, pan and filter is there any special reset or adaptation mandatory? @werkstatte-bmwonly9515

[@aaboud123]

Hello, I have the same transmission on a 2006 740i. The transmission shifts smoothly during acceleration, but during braking or downshifting, I feel a jerk from going to 4th to 3rd or, possibly, 3rd to 2nd. It feels similar to driving a stickshift while downshifting to 2nd and letting go of the clutch quickly. Any idea what that could be?

[@amsimkiss]

Very good video. I have fault codes 4F85, 299A, and P17E5. I was considering the valve body kit, but now I'm just going to scrap the car and buy something new instead. In meantime, it drives half decently in manual mode and I just erase codes when they pop up.

[@bluntintheair]

Yeah man in having that same 4F85 code as well. Looking at going manual, hopefully the install will not be to bad.

[@smamas114]

The service told me that the gearbox sliping in 4 to 5 but i have checked myself the presures and just the clutch E its -150 and the max its +-400 , i havent seen any sliping ,there are no fault codes on transmision , what do you think if the pressure it's ok there wouldn't be any sleeping right ?

[@likits1999]

Hi Viktor, Wheres the high pressure release valeve on a 6HP 21? My 2008 528i lost almost all the transmission fluid from March 2024 til about June 2024 when I stopped driving it to protect the transmission. Im changing the pan and the fluid with genuine parts right now and I cannot figure out where the flui escaped from. I degreased the whole undercarriage in June and I can see oil leaking from the pan but the oil level is fine. The tansmission maybe had 2 qts in it plus whats in the torque converter but the pan is moist with oil, not ATF. The vehicle had been driving great even when losing the fluid. Is the drain plug the actual high pressure release valve and thats why it creaks when you turn it to remove it? Thanks in advance.

[@s21ultra70]

I'm not sure if you can advise I have a 335d UK 6hp transmission. 1) I have slippage in 1/2 gear. On either hard or soft acceleration, the 1st gear holds and will redline without shifting into gear 2. I have to let go off the acceleration and tap the paddle shift to change gear. But there is still a big delay.... 2) Sometimes, when accelerating hard, I have a gearbox malfunction in gear 3/4. Gearboxndoesnt work and drives at a minimum speed. This clears after a car restart. I've only ever had gear 3 or 4 ratio error come up 3 or 4 times in the past year or 2 off this happening. I've chamged the metatronic sleeves and gaskets. Done 2/3 gear box oil services. Changed the basic serviceable parts. Worked good for a while but carried on with the issues above. I have no chamged the gearbox solenoids. I also did an xhp tune stage 1, which helped a lot with the slippage, but as mentioned above, it happens randomly but less often. I'm scared to drive the car fast or to have fun. I try my best to minimise hard acceleration (works great when jt works)

[@werkstatte-bmwonly9515]

You have to start with mechatronic pressure dampers, separating plates and solenoids. If that won't work you have to do the transmission clutches and bushings

[@Tom351993]

How did you go about putting the xhp tune on Many thanks

[@waynehazard-ql5sv]

Hello Victor. Love the videos. I am a Jack of all trades I think lol. I have been trying to get my 07 750li going. I did twice. First transmission when I bought it I changed bridge seal, tube seals, sleeve and pan along with fluid. It worked for a week. Then I changed transmission with a used one and kept my tcm and drove it for a few months. I changed my valve cover seals and all other seals that cause oil leaks on engine. When I finished that and tried to drive it I got a fault code 4e89 solenoid 1 or 2 mechanically jammed. Bought Sonnax kit and rebuilt valve body but still have the same issue. I can drive for a while but once I come to a stop or slow down I get a fault code and limp mode.

[@werkstatte-bmwonly9515]

You problem is TCM. Not the transmission or the mechatronic. I've seen it multiple times. TCM (transmission control module) is the back part that's attached to the valve body. Find a used one or from the donor transmission

[@waynehazard-ql5sv]

I already got rid of the donor transmission with tcm. All I kept was valve body. If I get another TCM I will need to get it coded right or would it possibly be plug and play?

[@waynehazard-ql5sv]

Also what is it about the TCM that would make it register as solenoids mechanically jammed. I test drove it one last time after replacing fluids and seals again and when I got home to back into my driveway is when the transmission jumped back into Park from reverse and I got the fault again.

[@werkstatte-bmwonly9515]

We had these issue with the that exact fault code caused my TCM. It's internally shorting. A used one without coding might work

I'm scratching all around forums and youtube, changed fluid, the 4 mechatronic seals, the 1 main and the connector on an e92 335d 6hp28 box, did reset adaptations (idk if it was a mistake or not) shifts amazing BUT 2-3 it feels like it slips, brings 100rpm up, drops, then shifts. Saw a couple of videos, same car on acceleration, absolutely the same rpm up/down then it shifts to 3rd. Torque converter or loss of pressure until it locks completely?

Hope someone can help. i have a 2011 335xdrive auto with 100K miles. Only mod is MHD S1, not raced or abused. The trans had a leak and I wasnt aware. The Trans would have fault and go into limp mode. When I took to shop they found with only a few quartz in it. They replaced fluid and filter- car drove but felt some slipping still. Trans alarm still active. They opened pan again and changed the seals. They changed seals and still have slippage between 3/4. The shop is german car specialized in porche but not diagnosing right being they are doing it again now to change solenoids. Do you think the slippage is solenoids being the trasmission fault still active?

[@werkstatte-bmwonly9515]

The way I look at it you'll have to replace the valve body plate with solenoids anyways. So start from doing that and hopefully you restore enough pressure and you won't have to remove the transmission. Make sure to replace those Pistons that damper pressure in the valve body. Just the new solenoids won't do the trick.

What is the fault code description?

Thanks for the reply. The fault code description is Ratio monitoring clutch B. I looks at the clutch B and it looks burnt. Does that mean my transmission is bad?

Hi Arturo, If you replaced the solenoids and still have short or open circuit for the solenoid that means your have a bad TCM ( Transmission Control Module). That's the black plastic part that's attached to valve body and holds all solenoids. You can separate it from valve body pretty easy. You can use a used one but it depends what vehicle you have.

I have a 6HP28X E shift in an E70 35D that has E clutch ratio codes and will intermittently go into failsafe mode and remains in 3rd gear until you stop and it resets. This has been slowly getting worse. The transmission was supposedly overhauled after only 120,000 Km's. It now has 186,000Kms. I was sure the bushes were not replaced last overhaul, and now I have stripped it know that was the cause. On recommendation, I have out a Sonnax Gen 2 zip kit in the valve body, new ZF solenoid set, new DuraBond bushings. I measured all clutch packs and friction disk thickness was per original new plates, so I did not replace them. All other parts are without fault as expected from the low kilometers. When assembled, I have reverse only, no forward, and it even comes into reverse with Neutral selected. This is not my first 6HP26 transmission repair by the way, but it is the first time I have put a full zip kit in a valve body, only doing the sonnax piston set before. I followed the Sonnax guide. All clutch packs were air tested on assembly as normal. I have valve body out again and will measure the new solenoids tomorrow and see where from there. Any thoughts of where the problem may be?

Got an 08’ 335i FBO with the 6HP tuned with XHP Stage 3. recently did a trans service replacing solenoids and Mechatronic sleeves, alongside fluids and trans pan. Transmission shifts awesome and adaptation values are within spec. One issue I still have though is when my transmission is cold, my RPMs will tank to less than 1k (even when I am in 3,4,5th gear) when I let off the gas. If I keep driving and let it warm up (~70F) then it starts acting normal and shifts perfectly fine. Any idea what this could be? My guess is loss of pressure / hardened rubber parts in the valve body. Could be wrong though. Car has 75k miles currently

So step one is to check the fluid level. If it's full we just replace the transmission because they aren't expensive these days. Of course you need to make sure you don't have fault codes for a stock solenoid. If you have solenoid faults then do the service and replace solenoids. If trany is low on fluid then fill it up and drive it for couple of days. If it shifts fine them do the service with solenoids. Also clear the fault codes and see when it slips.

[@werkstatte-bmwonly9515]

Marks aren't the issue. The shaft gets worn out and it loses pressure with the bushings. Replace the bushing that goes in the oil pump at least. Check the shaft with your nail, if it's really worn I'd replace the drum. If minor it'll be just fine.

Where can these parts be purchased

[@antslife1089]

Hello, thank you so much for your videos. I was wondering if you could help me. I recently changed the solenoids, sealing sleeves, and the bridge seal, now the only thing that works is the reverse. I have INPA software and the 4f81 code is coming up. I hear a rattling sound form the transmission sometimes it will catch for a second to go forward, and it will sometimes pull forward in manual mode 2nd and 6th just a little, enough to kinda pull back into the garage but it even stopped doing that.

[@werkstatte-bmwonly9515]

Are you sure you filled up the proper amount of fluid? Did you have the car idling while filling it up? It sounds like a pressure loss. I would remove the valve body and double check the adapter gasket. Also make sure it's the correct part number. If that adapter cracks or installed incorrectly it'll lose all the pressure and do what you described. Also if you only filled up 4 qt or so it'll do similar

[@antslife1089]

@@werkstatte-bmwonly9515 Yes the car was running and I used 8qt. Is the adapter gasket the bridge seal? My old one wasn't cracked but I will try that.

[@werkstatte-bmwonly9515]

Was the vehicle running fine before you did the service? 8 qt is the correct amount so that's not the issue here. Make sure you didn't mix up solenoids. Did you take a picture before you took them off? I always suggest taking a bunch of pictures.

[@antslife1089]

@@werkstatte-bmwonly9515 Yes, I took them out one at a time, Do you think they sent me the wrong seal kit? because I ordered all OEM ZF seal kit for 6HP19, is kit the same as the 21 kit?

[@werkstatte-bmwonly9515]

ZF 19 and 21 are very similar but these adapters aren't all the same. There are several sizes that's for sure. Let's assume.yours is thinner then you would lose pressure. I'd remove and compare side by side..I'm almost positive it's a mechanical issue. Remove and double check everything. I also had a tech that didn't torque the valve body bolts and we had clutch slippage. We only found out when we removed the pan again.

[@stephenwhite5444]

Great video! Do you think if a zf628 has 160k miles and no idea if fluid has ever been changed....should I change it or leave it alone? It runs good.

[@werkstatte-bmwonly9515]

I'd replace it. It's an old myth that if you change the fluid, transmission might fail. In over ten years I have never seen this happen. Now I WOULD NOT reset the adaptation values at this mileage.

I bought a 318d E91 Car has 295xxx Bmw dealer serviced up until 190xxx After this km, no service history. Should I flush/wash the transmission and change oil. Or should I not flush it and only change the oil? Sometimes you can feel the gear change, it shifts a little uncomfy.

Hi there i just watched your video and well explained, im getting code 4F8D after driving to operational temperature before and after replaced stuff down below... I recently replaced solenoids, separating plate, accumulator seals with rubber version like OEM and valve body seals (5 pieces) ... all the values are A -134, B -50, C -55, D -38, E 0. Still on learning adaptation process... what causing for that code... 2006 530xi , thanks in advance...

[@werkstatte-bmwonly9515]

1. Worn bushings 2. Piston pressure dampers inside the valve body 3. Input shaft is worn 4. Solenoids 5. Damaged clutches

[@hanynowsky]

2010 BMW 335i xDrive vehicles. The transmission may go into failsafe mode, with fault code 4F8D (ratio monitoring, gearshift 5-4 - plausibility) stored in the EGS. The cause is over-sensitive EGS software. The fault may occur during a 5-4 downshift only in vehicles with either low mileage, a replacement transmission or after a reset of the adaptation values. The transmission adaptation occurs only at a transmission oil temperature of 75 degrees Celsius or higher (167 Fahrenheit). Once the transmission oil temperature of 167 F has been reached, carry out the adaptation as follows: 1. In drive position D, increase vehicle speed up to 4th gear at about 25 mph, but do not allow a shift into 5th gear. 2. Allow the vehicle to then coast to a stop and keep the vehicle stationary for about 15 seconds with the brake pedal applied. 3. Next, with the vehicle stationary, change from D to N and back again to D. 4. Repeat steps 1 to 3 approximately 10 times.

Hey, Viktor! I will want to do a full transmission service on my 2009 bmw x35d, can you please make a video where you explain what are all the steps a mechanic has to follow and check to make the service right please? The mechanic that will work on my car has past experience with these transmissions, tho I would feel much better sending him your video ^^. Also this video is really informative and will 100% show him. Just subscribed, thank you!

[@Rosuvlad12]

how much would cost something like that?

[@azizmerali4639]

I am in Canada and have a 2011 BMW 750xi with 175,000 km (about 110,000miles). No issues with the transmission but it has not been serviced ever. Should I be servicing it? If so then what should this service include? What fluid do you recommend? Thanks for the great video.

[@werkstatte-bmwonly9515]

ZF fluid is the best of course but expensive. There are plenty of good brands that work just fine. Even cheaper redline fluid does the job. I haven't seen a car fail because the original ZF fluid wasn't used. There's always a different issue behind it.

[@carolriley9392]

I used valvoline max life. 30,000 miles no issues

[@TopherHax]

I know this is 6HP video but I have 8HP45 in my 2012 X5. I did trans service at 95k miles all OEM parts, 2 months later the trans shudders in all gears light acceleration. Then I installed REDLINE D4 ATF fluid and immediately all problems are gone. Is this because old transmission and new OEM fluids are a bad combination? I am thinking the lock up clutch in torque converter was slipping since it was all gears. REDLINE fluid is a bit thicker than ZF also.

[@werkstatte-bmwonly9515]

Using thicker fluid would help clutch slippage. That's what dealerships do all the time, they have a car with a problematic transmission and they add transmission additive. Sell the car and new owner decides to service it a year later. Shop does the service and now the transmission has issues. So the idea is that the service is bad for the trany when it's a much deeper problem than the service.

[@garygatten1154]

You prefer Sonnex kit over Transgo? Or do they fix different problems? Is rebuilding the valve body really that difficult? Seems like if you're careful and take pictures and such it's not a problem?

[@werkstatte-bmwonly9515]

I've never heard of transgo. I've only used Sonnex. If you take your time you should be fine. Remember there are springs so be careful when separating the plates.

[@garygatten1154]

@@werkstatte-bmwonly9515 I've heard the separator plate needs to be replaced / upgraded? What to you think? FYI i have a 2007 750i. Based on what I've read, seems like I'll need to pull the valve body and get some numbers from it before I order anything? FYI, link to Transgo kit: TRANSGO SK6R80A

[@werkstatte-bmwonly9515]

Yes there's going to be a three digit number with a letter in front of it. One side will have letter A and another side letter B. Very common numbers for example A053 or A054. You don't have to remove the valve body to see the plate. Just remove the oil pan and you'll see it on the edge of the valve body. Pretty big letters

Sorry for the question, you're sure you have a ZF transmission? They used GM in 2006 as well and they have that downshift issue. GM would have a metal pan and ZF has the plastic one. If it is a ZF you probably need a pressure dampers kit, sonnox sells them but it's not a really diy job.

[@werkstatte-bmwonly9515]

Hi there, this would be clutch ratio monitoring. 5 series is the most common with the bushing failure. Replace the solenoids and do valve body service asap, you might postpone the problem for a year or even longer. Make sure to replace pistons that damper pressure in the mechatronics that I've mentioned.

It's always a step one to do a full service with Pistons, solenoids, fluid etc. And reset adaptations after that. Pressure loss is the most common issue with these transmissions and the start of all the problems
