You're a legend Gary, I rebuilt my 6HP28X valve body (sonax kit, separator plate, solenoids) after carefully watching your videos
Is 6hp28 way different inside than 6hp26? Can’t find good video of 6hp28
Another entertaining and instructive video from Gary.
As usually - just great!
Good job Gary
Literally the most useful zf gearbox videos ever.
Do you know what the ratios in my Bmw 645ci will be? Do all zf6hp26 gearboxes have the same ratio?
I would recommend a microfiber towel instead of cotton to avoid getting fibers in any of the check valve components. I've used Redline D6 fluid with good results for the last 100Kmi.
Great Video Gary! Is it normal to overhaul all the solenoids with no other complaints? Is that a maintenance item? If so, at what mileage should this be done?
Great Video thanks but I'm unsure of the 6 sleeves and springs vs the rubber ones
Can you explain I didn't see you put them back in
Hi Gary what grade sanding block did you use to clean the surfaces?
Many thanks 👍
Dude i have exactyl this transmission but i swaped it into genesis coupe, just had to rip the trans out and going to try this
i just got a 05 navigator with the 6hp26 that im having to replace the engine and thought about rebuilding the trans while the engine is out. at 200k is that a good idea or would i be better to wait until it starts slipping or showing issues and save the $800 in parts till then
I have a GA6HP26Z in a 2011 335D, I have a rough 2-3 upshift but only at low speed low load, if I apply 60+% throttle it shifts like a dream. I changed my fluid, pan and seals and the old fluid looked really good for 100,000 but it didn’t help my rough shift. Very strange issue as all the rough shifts I’ve ever run into got worse with higher load and speeds but this one gets better. Ever seen something like that? I’m considering a sonnax zip kit and solenoids but I’m worried it won’t fix it
Hi Gary, really appreciate your explanation. I have a question here not sure your have seen it before. BMW E46 throws out a P0720 code, saying that it is an output sensor issue. Have you fixed similar issues ...? Many thanks. Wil from Sydney.
The Trans is a ZF6HP26?
Hello! where can i get that stone to polish my valve body?? or whats the name of it? i bought one to resharpen Knifes which look very similar but its not straight enough to run it over! im afraid its going to scratch it.... Thanks
How similar is this compared to the 6r80?
Hi Gary, how do you actually clean the valve body? Do you use brake cleaner directly without removing the rest of the parts on the valve body? thanks
I have a wash tank with mineral spirits
Hi Gary thanks for another great video, I used one of your previous 6hp videos to help me rebuild the valve body on my 2006 X5 3.0 diesel and it was a massive help (even though I have 37 years as a tech), unfortunately the rest of the transmission 165000mls is slipping in 1,2. I have bought a low mileage 6hp26x( also gen1) but the valve body has a A51/B51 plate and my previous body the A/B52, question is will my old body fit the new transmission as I fitted new solenoids and dampers etc.
Keep up the good work and enjoy your work all the best Matt (my son shares my account hence the different name and picture 😂)
Yes it will work, install the valvebody/tcm as one unit
@@GaryFerraro thanks for your help 👍
Gary,
Great video.
I' not sure if your still responding, I have the following question.
I have a ZFHP26 transmission and when i removed the valvebody i saw that the input speed sensor (part Bosch 3267033) was melted at the sensor end.
I located a replacement with the same part# and it looks identical except the the 2 connections are joined together and form a spade attachment. In my transmission the 2 connections are soldered individually, it looks like the end spade connection was cut off.
Are you familiar with this situation, do i just need to cut off the spade connection on the replacement part and solder the 2 connections individually.
Any help would be appreciated.
regards
I do not work on the TCM's I send them out for repair
Also what do you use to clean up the valve body ,before put the plate in? Whats that brick also that you glide over?
I have a mineral spirits tank, the stone is a fine sanding stone to get the burrs off so no crossleaks
Excellent video(s) Gary. I have a bent/broken pin. Is there anyway to replace the (I believe you called it) TCM? The whole plastic which includes the circular pin adapter?
you have a broken pin where the harness plugs in, so a broken pin on the TCM?
@@GaryFerraro yes. Pin #2 ~ low can
Is there a way to test the solenoids? QC isn't what it used to be, afraid new may not be better. What about sonnax or transgo kits?
Can only Ohm the solenoids, or send them out to a place that can flow test them but the price came down so much on the solenoids doesn't really pay to have them flow checked just change them
Hi Gary, I have a nissan sentra b14,when I stop at the traffic light, the car don't move unless I tip the accelerator, then the driver gear comes back in, I opened up the transmission but need some guidance to pin the problem
What year is the car
So was the transmission experiencing issues or was this preventative maintenance?
preventative maintenance
Looks like those original soleniods where not that old (faded) What was the reason not to change out the 6 small check balls ?
client wanted the work done. i changed out the Dampers not the check balls. The dampers are rubber and tend to flatten out
@@GaryFerraro Thanks for the reply. Much appreciated.
Hi Gary! Can u please tell me what do u think can cause “kick on the back”(like someone bump into u) from 2-1(car has 120k/ did transmission flush at 100k)? This happen only when the transmission Oil is warm(after driving from cold start for 10-15 min)??do u think the solenoids change /oil/seals/zipkit sonax will fix this? Thank you
Mention also that sometime on verry agresive driving does same kick from 5-6,,also indont have any errors on the idrive/insta/inpa
@@ThesteliFLo If happens hot can very well be a valvebody issue, something with Pressure reg valve or Lube reg valve. I can't say for sure a Zip kit will fix this as i do not use them
Forgot to mention i have a 6hp19 bmw transmission,what valve body kit do u use to replace the internal components ??
@@ThesteliFLo What is the year of the car
Hey Gary, thirst of all, thanks for all those great videos!
May I ask you a question?
I got an 6hp26 in my E60 BMW and have already serviced my valvebody completely.
But it hasnt fixes my Problems, E clutch adaption values are steady going up to 700 mbar.
Now I want to rebuild my whole transmission, I would estimate my bushings are gone. Is it correct, if I renew those bushings, the friction disks (not the steel disks), and the seals of each drum? Or would you do more?
Greetings from Germany!
Hello, That is probably your trouble, You may want to aircheck the drum just to confirm it is not cracked
@@GaryFerraro yeah I will do that for sure, thank you :)
But you think the parts I listed that I want to change are a good start?
@@andreenge4699 For the problem you are having yes, did you replace the solenoids when you did the valvebody
@@GaryFerraro thank you, then I hope, that I am on a good way :)
Yes, I got them checked in a shop nearby, they are all within range and seal properly under pressure.
I got one more question in mind. I saw that the Bushings in the E Drum and in the output shaft are somehow locked in. Are they still changeable without heavy machining?😬
@@andreenge4699 That is the small bushing, the output shaft i never change, if there is play in the E drum, you can change that one. Make sure the rear stator bushing gets done, that is probably your problem
Hi Gary, thanks for your great videos. I'm having trouble with flared shifts on all gears after replacing solenoids and fitting zip kit, bridge/sleeve seals, pan and ATF. I'm struggling to diagnose the problem - do you have any ideas on where to start? 4 out of 5 of my adaptations are negative mbar (-10, -158, -268, 83, -31). Thanks again for your fantastic videos.
Have you reset the adaptions after the work was done?
@@GaryFerraro yes, reset and all seemed fine (no flares) for about 300 miles. Then one morning it suddenly started flaring very noticeably. No error codes
@@z0mfglogiczero I had a similar problem once i reset the adapts about 400 miles later having problems, i did not like the wat the Bridge seal looked so i changed it and solved my problem, I had the negative fill times too. check or change the bridge seal
@@GaryFerraro Gary, thank you for taking the time to help...will let you know how I get on after changing the bridge seal. Have a great evening and thanks again, you're an absolute legend
@@z0mfglogiczero Make sure your also putting the correct seal in, the ZF6HP26 and the ZF6HP19 are different
Hey Gary come on help us out man where do you get your ZF parts from just give us the answer from all over the world
I get from Transtar and from Eriksson's in CT
Nat at Eriksson told me NOT to reset adaptations unless doing a full rebuild - what are your thoughts Gary? What's the pros and cons of each? This is Nats quote to me after I purchased the ZF and Sonax kit: " Hi Jake, we recommend NOT resetting adaptions unless transmission is completely rebuilt Just driving trans will allow it to readapt itself to the new solenoids"
P.s I have done about 6,000 miles on the new valve body and it works fine, only thing I notice is it can be harsh on the downshifts - I figure this is the steel springs and components of the sonax kit?
@@jake6084 I have reset shift adapts plenty of times when swapping out solenoids never really had a problem. To me it depends on what the situation is or what the complaint is..
@@GaryFerraro thanks for the reply. Any idea why Eriksson would advise against resetting adaptations? I couldn't get a clear answer and figured it was something to do specifically with the gen2 e-shift valvebody. Cheers Jake
@@jake6084 If trans has high mileage and clutch packs may be worn, some may think it would make matters worse if adapts were reset
I have a 6hp26 in a 2008 range rover that has thumping and hard shifting problems in low gears, generally at low speeds (115000 miles). I just did a full service, including changing all solenoids, bridge seal and jump tubes with high hopes that it may solve my issue... the fluid was dark and there was some fine matter on the magnets, but nothing that seemed out of the ordinary (pan dated 2014). I have put a few miles on it now and the problem is still there. Would you recommend that the shift adaptations be re-set or will it learn over the next few hundred miles that it has new solenoids? If the problem does not resolve with a reset would you recommend a valvebody overhaul before going further? Your video is very good and gives me confidence I could complete this procedure.
Do you feel a 2-1 downshift bang?
@@GaryFerraro occasionally a bit, but the issue is more pronounced while upshifting. low speed, light throttle. thumps a bit then bangs into the next gear.
@@jfr55man Do you have a scan tool to reset shift adapts
My friend has an autel that i think does it. Im just a little hesitant as i have heard it can make things a lot worse. Ive got about 1000 miles on it now, seems like its getting better.
@@jfr55man ok, When the adapts are reset car drives very bad until it learns. Quick tip, These go through adaption when the trans fluid is above 130F and no codes present on Trans or engine. Once hot do a lot of starts and stops
ZF6HP28 in a bmw 2011 335d. What would cause the transmission to shift early? For example goes into 3,4th at 1500-2k Rpms when going slow lime on neighborhood street. New solenoids, seals, filter and fluid.
This trans is all computer controlled, if going slow and light on the gas it may shift early. When you take off with heavy throttle it will shift later
@@GaryFerraro Thanks for the reply Gary…but something is definitely wrong. For example. In normal (non sport mode) I take of in first (even with moderate throttle, it will shift into 2nd and for only 500 rpms go into 3rd right away…even when trying to accelerate hard. New oil , filter, sleeves, and solenoids. I don’t know whether this is a valve body issue or a clutch slip?
@@threetreewoodworks4200 Are there any codes present? do you have a scanner that shows live data?
@@GaryFerraro I have XHP and it shows no fault codes.
@@threetreewoodworks4200 Can you see live data? Like commanded gear ?
Gary, I was recommended Lifeguard 8 for my 09L Audi transmission. Is that the right one? I see you always use the Lifeguard 6.
6 speeds i use lifeguard 6
Request line - 10R140 and 8L90.
Don't get to many of those yet but will keep that in mind
@@GaryFerraro 👍
whats the difference between AG6HP26Z to this 6HP26?? thanks
Hallo
Got the same question!?? 😁
@@carpfever683 i contacted the company that sells rebuild kits and they said separator plate has a Number that identify it and differences can be different bore Diameters on valves and plate Thickness as well
Where can I buy that ZF KIT
Where are you located?
@@GaryFerraro Tanzania - East Africa

Hey Gary, I was working on a zf6hp26 stuckel 1068010129 with the same b052 plate and my valve body only has 8 check balls and according to zf this is normal. Have you ever come across this before?
the checkballs may vary from model to model depending on the year
Love your stuff Gary!
