ZF6HP26 Valvebody Service
HTML-код
- Опубликовано: 5 окт 2024
- In this video, I go through the valvebody replacing the solenoids, plate and rubber dampers that were actually coming through the valvebody. This trans was producing a code for clutch E monitoring, owner of the car wanted to try valvebody first. This did not fix the issue, so we will be pulling the trans and installing a bushing kit.
hello again....my repair was a total success...thanks for the in depth videos....i was in control....split the valve body and replaced dampers and end seals along with separator plate and solenoids....and did not loose any check balls....trans is what i would deem almost new....clutch pressures are great...shifts are fantastic after the adaptation drive....thanks again
Great, thanks for the update
Great Content.
I am doing some service to my 07 LR3 6HP26. Being a retired Rover tech, this is pretty straight forward but its been since 2012 due to retiring. Trans is in limp home mode (3rd gear), P0964 code and leaking fluid. Fluid is dirty as well. Im doing the following: New seals, rubber tubes, bridge seal, dampers, separator plate, solenoids and Type B trans pan and hardware. Thanks for the walk through.
I have a LR3 2005 Doing the same thing.
Where do you purchase the kit ?
absolutely fantastic Gary....I am doing this same project this weekend and also replacing the end plugs....thanks again
Thank you
Hi Gary. Very informative and helpful video. I am in Turkey and recently have rebuilt my 6hp26x on my e53 by ZF in Turkey. The problem was my car was 220k km and after i changed the oil 3rd time, i resetted the adaptations (i should not have done), although i followed zf adaptation procedure problems started. From 1-2 sonetimes it was reving up and suddenly change with a huge bump.Problem was e clutch and all flattening seals. All changed. It was very exciting to see the whole process in your video. Btw, you are are really kind to answer all the questions, keep up the good work!
Hi Gary,
Great video. Thanks.
I have a 6HP26 in a Ford. They were used on local product down here.
The trans has an issue with slippage in 2nd gear with medium to high torque. Also, it will not shift from 3rd to 4th with zero/low torque. Gears 4, 5 and 6 are fine. As it attempts the 3-4 shift, it tries for fourth, does not find it and goes back to third.
When driving it, I use the manual shift. I take it easy in 2nd then when changing from 3rd to 4th, I press a little on the accelerator to increase torque or do the opposite which is lift off the pedal completely. Thus the trans has either positive or negative torque going through it. Like this, it shifts OK.
I too changed the bridge seal,the cylindrical sleeves and new fluid plus filter. It did not make any difference.
Later, I reset the adaptives and it made it a whole lot worse.
I have another trans for it. I was contemplating either swapping the valve bodies or the complete trans. I saw this video and it was swaying me to swap out the valve bodies until I saw your comment that in your case it didn't fix it. Oh well...
In the meantime, it has just done a 2,000km interstate round trip like this in very hot conditions > 45 deg C. Like I said, gears 4 5 and 6 are good... Didn't get any worse.
Your comments would be welcome. Thanks.
Ok, I would like to know if any codes are present in the engine or the transmission
Gary Ferraro
Hi Gary,
Sorry, been busy of late.
The codes are:
p0732 2nd gear incorrect ratio
P0783 3-4 shift
There are no codes for the engine.
Thanks
Danke für das Video. Werde bei meinem 745d auch durchführen. Hat keine Probleme , aber nach 190.ooo km kann man es mal machen.
Top video.
Hi Gary, great video! Thanks for taking the time to put out such great content. I have a 2011 E70 X5 M with the 6HP26Z transmission. It's not throwing any codes, but it has become a problem where under normal driving conditions the car shifts from 3 to 4 to 5 rather rapidly without building RPMs much through each of the gears. If I get my foot in it, then the problem never shows up. But if I don't, the premature shifting occurs and then I really have to step down to get a downshift. And then off like a rocket it goes. The way it's behaving, something just doesn't seem quite right. I don't know whether all is normal and it's just the car trying to eek out some kind of fuel economy (cough - 12 MPG) or if my gut is right. It's time for transmission service. I'm planning on dropping the valve body, and replacing all the seals and the solenoids since I've now hit 80K miles. I'd much rather do this right once than have to do go back in to do something I could have easily done the first time. Is there anything else I should/could do based on my problem description? Do you have any thoughts on what the problem might be? I really appreciate it if you are able to reply. Thanks again for the great content!
I have same problem and am 100 sure it's mechatronics solenoid
Greetings. After repair with hard drive and shock when shifting down from 5th to 4th gear. Replacing the valve body and booster valve did not solve the problem. The clutch air check is excellent. There are no error codes.
you have to reset the adapts
@@GaryFerraro Yes.
Thanks for sharing Gary.
Thanks for watching
Again another great vid
Thank you for posting this. Does anything need to be done to the valves themselves? Like should they be removed, inspected, and cleaned
Very good
Gotta love this stuff you do. 👍👍👍👍
Thanks for watching
Great videos
Great transmission , they are easy money makers .
yes, nice trans to work on
Brilliant video
Thank you Grant
@@GaryFerraro No problem. Put onto you by Pete Holmes.

Buongiorno Gary complimenti per i tuoi video desidero una info meccatronica bmw 6HP26 desidero saper la coppia di serraggio Grazie anticipatamente
Hi Gary, Good to see your videos, Gary I am finally going to fire this thing up and see how good of a job I did on my 05 545i 6HP26, replaced Bushings, solenoids, intermediate plate, Bridgeport seals. I even replaced all seals on leak prone areas on the engine, now I need instructions on how to reset adaptations on this transmission I was told it's like a drive cycle
that's got to be completed.
Do you Know where I can get that information Gary, please.
I will keep you updated on how it all came out., Oh I forgot to mention I have INPA
Thank You Gary Best Regards
Make sure no codes are present in transmission or engine, trans temp needs to be at least 130F, after the adapts are reset drive the car and let it upshift through all the gears. do like 15 to 20 start and stops
Thank you verry much👍💪⚡️🧠
welcome
Hello Gary, I wrote to you a while ago about a 08 impala 4T65E issues. I lost first gear, I could drive the car if I manually shifted to second, then shift from 2nd to 3rd etc.. while stopped I would have to move it down to 2nd.I did some basic checks, harnesses were good on the outside, cleaned grounds. I added some seafoam trans fix and more fluid. After a few drives, first gear came back, then it went away. When first came back, it would shift 1 to 2 then 2 to a hard 3 after 3 there was no 4 or OD. Other times from a stop it would shift 1st to second have a delay then slam into 3rd. Then I would only have 2nd. Only a few times did it drop 3 and 4th gears and rev high after 2nd reached its shift point. Other days it was no 1st but could manually get the other gears to work. Then I had all gears working as long as I had low rpm range. Now you asked me then for codes. There were none as the battery was changed. Well it has taken this long and many long trips to get this damn light to come on. Tonight if finally did. Tonight after a 2 hour drive I stopped and it felt as if the trans was trying to apply a gear and was popping in and out. So what the codes read is a P0700 and P0977 so I ask you expertise. Sorry for posting on this video. I can't remember how to send a DM
What is the definition of the 977 code?
@@GaryFerraro Definition I got was Shift Solenoid B Control Circuit High. This make any sense to you? Weather has been to cold to work on the car outdoors. What I found tho that was interesting is that freeze frame data said the car was in open loop.
Super informative! Did you say you 'wet sand' the valve body halves to clean them? Also, what are your thoughts on the foam strips that may come with a new ZF solenoid kit? THANKS!
Perfect video..
Good morning Gary.
Thank you for Your reply and getting me in touch with Nat at Erikssons. Hope all is well Gary. as I mentioned before I'm looking to do the same trans service to my 2007 530xi with 2004k mainly as preventive maintenance. I recently got this vehicle and although I'm Not showing any codes at this time I'm experiencing a jolt as I'm coming to a complete stop its Not always it's kind of like when someone rearends you from behind and I also noticed something similar as I drove up to 90 mph then it felt like going over a potwhole, it completes the shift and goes on after that. Being new to the Beemer community and through lots of RUclips videos I'm wondering if once I'm done with this service do I need to have this Reset? I hear a lot about this IMPA BMW Software that will also also amongs other numerous things with completing the filling of the trans fluid at a certain temperature and also with the resetting once I complete this service. So I guess my question is, Is this resetting necessary? I asked a local mechanic who advertised himself as Especialicing in German vehicles. His response was that as long as there were No codes showing up on the dash, this was Not necessary. Would you agree with that Gary? Looking forward to hear from you!
I was wondering where you got the parts for this job, especially the filter screens
Hi Gary! Thanks for instructions, great work. I noticed that the mehanotronic you are dismantling has red oil? Lifeguard is light yellow?
Lifeguard is the recommended fluid but you can use a premium synthetic fluid like AMS Oil or Mobil one, they will work fine
Gary you are awesome and an expert. Where can I bring my car for service at your shop? I dont trust other shops. My range rover sport 2008 4.4L will need to be serviced. I had a leak in the transmission years ago and due to timing didnt stop the leak. I did eventually change the filter and pan last year. Since then had issues like flaring 2-3 gear and and sluggish on 1st gear. Funny part is that when cold car drives normal. I'm in nyc.
Great, i'm in New York on Long Island, My e-mail is gsferraro, e-mail me and I can give you my info.
@@GaryFerraro you have a shop in west hempstead?

Mr Gary.!!! I need your help!
2008 535i LCI 6hp21. Rebuilt gearbox, but will not go into PARK.
THE gears engage, that’s how I got the 9 liters of zf fluid back into it. But it’s up on jacks, so haven’t test driven it. Tested the Mv2 & mv3 solenoids it drew the correct ohm reading. But I noticed that when I stuck the screwdriver in the emergency park release in the gear selector switch, there was so much more slack, like it was too easy to move around… could this be the culprit???
Thank you for your reply!
Hi Gary, is there any difference between the 6hp26 and 6hp26X valve body or its solenoids? Also would a bushing kit for a 6hp26 fit a 6hp26x. I have an 07 X5 E70 3.0d I'm rebuilding. love your videos and thanks from here in Australia. Cheers Jake
im going to drop the valve body again this Saturday, the previous owner said the hard shifting started after the solenoid replacement so i am going to check the wiring and the connector and pins. would you happen to know the pin locations and valve locations for 3-4 shifts so i can check the valves? zf6hp26 -053
Hi Garry, I have a problem where my zfhp26 transmission slip in all gears including reverse after driving for about 5 minutes. All works great if i turn car off and let it sit for about 10 minutes. Then problem occurs again after 5 minutes of driving. All shifts smooth. No hard jerk . It just happened then feel like neutral
ur clutch is toast
Hi Gary. I have a 6hp21, changed the oil, pan, the 4 sleeves, and the square one. No errors. After the car is sitting for more than 6-7 hours, i shift it in D, stay with my foot on the brake for like 20-30 sec and release the brake to drive, it freezes like for a half a sec and then is like someone hits me in the back of my car. If i shift in D and i go straight driving for 20 min, at the first full stop and go it doesn't do that anymore!
Any suggestions?
Many thanks!! Keep up the good work!!
Good Job Gary. I just realized, is there not a gasket between the valve body and transmission body for the E and A feeds?
you are correct my friend
look like red fluid was used when they did the prior repair. is there a cheaper alternative to LG6 fluid? valvoline max life maybe?
That fluid would work too
Gary, very informative for me in Australia. Can you explain the purpose of the rubber dampers that were in such poor condition here please. I would like to understand what they actually do in the system.
They are accumulators. Accumulators soften the shift, if they are flat may have a harder than normal shift
@@GaryFerraro Excellent. Thanks very much Gary for taking the time to respond.
Great video, Where did you get the bmw mechatronics rubber dampers and plate
Could you please make a video of the run-in process after rebuilding a ZF 6HP-transmission? Best regards, Robert
Sure, i did a video, Victor's ZF6HP26 at the end i showed how to reset shift adapts with scan tool, Would you like to know run-in after adapts are reset?
Hi Gary, do you tasting this VB on vacuum. I have 6hp28 transmission with damage lubrication valve in VB. He has only 2 Hg of vacuum. It’s very small numbers… PR valve has 13-14 Hg… What do you think? And what can I do to correct this problem?
There is a company called Transgo that makes a kit for the lube valve, comes with reamers
Thanks for sharing Gary. Not too much of a setback as the valve body needed done also. Any good reason why these transmissions wear the bushings out?
TakeCare,
Bill
I'm thinking it's the material they are made from, babbit comes out but i put brass back in
hi great video can i ask the transmission solenoids you have 3 yellows 3 blue and one black {eds1 yellow eds2 blue eds 3 yellow eds 4 blue eds 5 blue eds 6 yellow and mv1 black does each one control a certain gear thank you
For the most part, I know EDS4 is for TCC and i think EDS6 is line pressure
hy, how many checkballs are gen 1 zf6hp26 with a051(!) plate, is really only 8?
Did you get to document the pressures on the clutches? Were the adaption pressures and temperature so high they extruded the damper rubber right through their access holes?
I use the Snap-on Solus scan tool, and sometimes it will not give me the info and some s it will
Hi there
On the E53 we have the 6hp26 with 7 solenoids on the valvebody, on E70 first generation (i think)we have the same box-6hp26 with 8 solenoids on the valvebody...Now the question is, are those two pieces compatible? Can we put the valvebody from the X5 E70 2006 on E53 Facelift?
In my case, on my E53 after the oil warm up , i have a "hard shifting" on 2-3 and on 5th gear my transmision surge (smth as loosing power and gain it back in a second)
I'm asking you that because i have a E70 for spare parts
Greetings from Romania
Is one valvebody an E shift and one an M shift?
Mine it surely is M shift , but i'm not sure about the X5 E70 valvebody - i know the code from it - 0260550024 Bosch with 8 solenoids. Thank for your reply
@@ciprianciprian1540 well if the other has more solenoids it may be an Eshift, if this is the case will not interchange, Are the solenoids the same color?
@@GaryFerraro Thank you for your cooperation, i didn't quite expect that...the last two solenoids are orange, color that i don t have on my valvebody...i ve reached the sonnax site and they provide good information overthere, so i found out that the 2 pieces are not interchangeable.

Hi Gary, I'm having a 4E89 solenoid valve 1 or 2 mechanically jammed issue on my 2008 750li E66 LWB . I am wondering would doing this service to my valve body fix the issue?
the issue does not always appear on a cold start, after driving around and car has warmed up, but as soon as I turn off the car and start it back up I get a transmission fault error and it will not pass 3rd gear when driving. Also my functions to switch in sport mode/manual mode no longer function when it shows transmission fault error.
I never had to deal with this problem but people that wrote in before and after the fix, they had told ne the fix was changing the valvebody
Hi Gary nice job 👍
But why you don't use the sonnax zip kit ?
never really had any issues where i needed the zip kits, between new bushings and solenoids, resetting shift adapts units shift real nice

Awesome videos on this 6HP trans, but you might consider a video camera upgrade for better quality. Thanks for the info you are sharing. Also, how come arent you using a Sonax ZIP kit in front of new solenoids. Ive read it helps a lot. Is that worth doing ? The check balls and dampers do they come in a kit ?
Thanks for watching, i have upgraded since, got new PC and extra lighting.

Im having a heck of a time finding those. Seems like everyone is trying to get me to buy the whole unit. I'm not ready to dish out that kind of money.
Hope all is well,
Looking forward to your response.
Cheers from Chicago!
The small parts came in the overhaul kit, but if the springs and filters are ok, you can reuse them. The only part you may have to change are the rubber dampers, the rubber insert is not sold, you would have to purchase the whole damper assembly(small little thing may 5 or 10 dollars each, could be 6 or 7 of them depending on the generation of your transmission. There also is a company called Sonnax that sells valves and springs in place of the rubber dampers that work well. If the dampers are flat they will need replacing, everything else you can reuse. If you want the rubber dampers, there is a ZF distributor in CT called Eriksson's industries, very good people there, if you need the phone number let me know. Greetings from New York, stay safe out there
@@GaryFerraro would you mind sending me the link or their number please and thank you for your prompt response.
in some country, service cost probably not economical, better just buy a refurbished unit to replace.
If you can get it cheap with low mileage, sure
Gary, do you recommend changing the fluid in ZF transmissions with lifetime fluid at some interval? Some people say to change it at 70k, while others say never change it.
70K seems a lot, i tell people around every 30K to change out the fluid and use the life guard
ZF's documentation for 5HP and 6HP series transmissions claims 80,000 - 120,000 km (50 - 75 Kmiles) recommended fluid change interval.

Hi Gary, thanks for your fantastic Videos! I’ve learnt so much from you 😊. I have a BMW ZF6hp26 off a X5 E53. I’ve rebuilt the entire gearbox and valve body with Sonax kit. I’ve replaced all the bushings as well. I’ve even replaced the valve body thinking I’ve done something wrong on the rebuild. The issue I’m having is that it has a vibration that gets worse as it warms up. In Park and Neutral NO vibration. Vibration is noticeably worse at lower revs while driving, over 2500 revs it goes away. Almost like a humming sound/vibration. I’ve even changed the torque converter - still same problem. Any suggestions?

do you have a vibration in drive at idle with foot on brake? or only when moving
@@GaryFerraro Hi Gary, with foot on the brake in Drive or Reverse I have the vibration. While driving as well under 2500 Revs it vibrates. Under high Revs, no vibration. Shift Change is smooth through all gears. Very responsive after the valve body repair and clutch/steel changes.

Hi Gary,
Have a '04 525i 110k miles. Zf6hp Never changed fluid/filter. Slight clunk from 2 to 1. Went into limp mode 2 times on 3-4 with higher rpm in the last year. Got e clutch ratio error. Less than 2500rpm all smooth though. Trans temp is good, 70c or less. Adaptations are all around +50 to +100 but c clutch is -400 and e clutch is 0. Shouldn't the fill pressure be ramping up if there's slipping? Heard some people see +600 before the clutches actually give out. Was planning to do fluid, filter, solenoids, sonnax kit and sleeves/seals. Is that a waste of time?
Clutch packs may be ok, i would say you either have a mechanically bad solenoid or a worn rear stator bushing, The 2-1 clunk could also be worn bushings. Does the car upshift 3-4 ok when cold?

@@jasonbuenviaje6250 Those issues with the 3-4 slip and the downshift bump I have traced to either solenoids or worn bushings, if you change the solenoids first, make sure you reset the shift adapts or the car will work the same way
Gary Ferraro No cigar Gary, I rebuilt the valve body with sonnax zip kit, new matching separator plate, new solenoids and new complete seals. Now it’s probably boils down to worn bushing on the stator were E drum is sitting or just replace all with the complete bushing kit?
Gary I have an issue with my Range Rover it throws out code p0735 after driving it for like 15 to 30 minutes and it basically doesn’t upshift I already changed the sleeves cleaned out the valve body and replaced the solenoids with new ones now the transmission shifts much smoother but has the same problem and the p0735 code pops up and I have to turn off the car and turn it back it on so it can shift normally and it runs fine after that n then the issue happens again and I have to turn off and on the car so I can drive it bcuz if I don’t it doesn’t upshift anymore
P0735 is Gear ratio error in 5th, sounds like the rear stator bushing is worn out causing a leak in the E clutch apply cicuit
@@GaryFerraro is the e clutch in the transmission because the transmission was rebuilt also what I did notice today is when I took it out to test drive it because I had someone do the relearn on it the temperature was pretty high and the p0735 popped up again I let the car sit and took it out again and was monitoring the temperature and the control module temperature was about 215 Fahrenheit and the trans fluid was about 220 221 Fahrenheit so it wasn’t running as hot as the first time I took it out today and I was able to drive without any fault for more that 30 miles and then code p0730 popped out so I’m a bit lost right now and the first time I took it out the temperature was about 245 Fahrenheit

Hi Gary, thank you for sharing your videos!!!. I have a ZF6HP26 that is on a 2007 BMW 550i. A few month ago the car was stuck on third gear. I end it up replacing all solenoids with OEM ones, all slevees seals, the bridge seal, the oil pan and the oil. The transmission worked good for three weeks. Now, after driving in traffic for 20-30 minutes starts overheating and goes to limp mode until cools down. This morning on a cold start it went into limp mode right away and I couldnt get it out of it. I never reset the shift solenoids when I work on the transmission, could that be a problem?
.I was thinking about buying the Sonnax kit and finish replacing all the parts inside the valve body. What would you recommend? Could do give me any ideas?
I would like to know what codes are present for the transmission

Hello Gary. is the Valve body service the same for the 6HP28X X5 diesel
Should be tea, the solenoids may be different, also check balls may be in different locations
@@GaryFerraro thank you for the prompt response
Hey Gary,
Please give your opinion : Had some slamming problems when cold 2y ago from low oil level, changed filter and all the gaskets, cleaned the solenoids with break spray, new oil, reset adaptation, was going great until I had some engine work and took off the transmission, mechanics told me I had an oil loss on the trans from the cable sleeve. After 1 month I completed some more oil than after a hard hill it slipped in a gear, driven good 100ml then on manual from 2>1 huge slam (no slamming until that day). The next day on cold was running very smooth until it got warmed 50-60c and the slamming started to feel more and more 3>2>1. If I wait some seconds before 2>1 it feels light, if I change right away boom car moves with breaks pressed.
I'm confused about what it could be cos the mechanics in the area don't know to repair this models. It started after a hill and slams only on hot.
Do they put too much oil ?
Too little?
Some solenoid broke or clogged? Something inside meca broke?
Some internal trans parts maybe?
Any advice is appreciated
Thanks

Amaaaazing videos. Thank you so much.
I have a 6hp26 valve body on the bench and I have a couple of quick questions.
In your experience, while the valves/pistons (including solenoid valves/pistons) are in place and in their slots in the valve body, should I expect to get slight spring loaded movement from them (all*) using a finger to push on them? On mine, a couple don't seem to have a spring loaded movement at all - don't push in. Others don't feel as if they are spring loaded and move in and out slightly by hand with no spring load... Is this normal?
Should I be able to get a SPRING loaded movement from all of them or do some have spring from the outer edge of the VB, while some have no spring feel or don't move at all? The VB halves are still together, plate in place, etc. I do have the solenoids out. Some of those valves don't seem to have any movement either with pressure applied.
Any suggestion advice would be greatly appreciated.
Some of these valves, may or may not have springs, some do just float in the bore, better off checking the valve for movement since some do not have springs
@@GaryFerraro Maaaan,,,, thank you! The problem I was/am having is a p0782,,, 2-3 or 3-2 shift issue. Don't know why or what to think... Was going to replace usual soft parts and solenoids, filter and fluid. Maybe even the separator plate. Car is a 2004 Jag XKR Supercharged Portfolio Edition. Nice car, lots of headaches.
i need help, i changed the 4 seals along with the bridge seal. turns out i have a A053 model. the tranny is still slipping and shifting hard. next will be the separator plate and dampeners.... is that what i should try next? the previous owner already replaced all the solenoids.

Please, how can you replace the turbine speed sensor ? The brown part of course, which attaches to the black part
The Turbine speed sensor is part of the TCM, I send mine to Europe, there is a company called Softelectronic that repairs them, just had one done last week
@@GaryFerraro thanks, i'm from Europe ! I'll do a search on them. 👍
@@MrAlpinab7 Softelectronic in Bulgaria
@@GaryFerraro nice thing is that the speed sensor is sold on ebay, amazon, etc, and it is only a 50-60 bucks part. Comes as the whole brown assembly, or just the black tip which is the sensor itself. Now, that brown thingie attaches to the black thingie, either through soldering, or replacing the green circuit board or just clamps onto the black computer and is held together by a clasp, and the metal pin and all the bolts which come through it. Im curios to see what makes it stick together (since the brown part is sold separately) before taking the mechatronic and computer apart myself. (It will most likely be a DIY job )
@@GaryFerraro found them, thanks, i'm in neighbouring Romania, so a yardstick away....
how much does it run to install a bushing kit in a 5 series with the 6hp19? I have one with e gear faults when warm, and im assuming the stator bushing is worn. =(
What faults are you getting? have you done anything yet? solenoids?
@@Stridenttube5 If ok cold and not hot, that's usually a bushing problem.
@@Stridenttube5 That would be considered an overhaul, i would say between 3K to 3.5K
@@Stridenttube5 The front assembly will come out as one, if your problem is only in the higher gears 4TH,5TH and 6TH, just replacing the rear stator bushing should fix it. I would also look at the E Clutch, they like to flake off and check the drum for cracks while the trans is out and apart

Any codes? What is the car doing?@@BillSr.
@GaryFerraro No codes. D6 light won't come on when shifter is in D6. The D4 light comes on instead. Switching from D6 to D4 is no difference. The light showing it's out of overdrive on dashboard doesn't even show up when switching shifter from D6 to D4. I can't keep it in D5 while towing. It seems to just keep shifting into overdrive
@GaryFerraro I had the battery cables off of it for about a week. I did take battery cables off and on during that week to listen to the radio. I had to remove the entire head liner to repair that dreadful Ford poor design of using plastic parts in their sunroofs. After fixing it and driving it is when the problem started. Oh yeah, I did have a used rear end installed in it, too, but the shop tells me they never touched the transmission or battery cables. No more than the drive shift.
Very informative video! Hopefully you might have some idea on a problem with my E60 with a ZF6HP26. It takes a while to engage a gear from a cold start. If I start the car in the morning or after sitting all day at work and I immediately select a gear D or R, there is no drive. If I give the car a small rev it thumps roughly in to the selected gear (I don't do this anymore, just an observation). If I start the car and wait 20 seconds then select a gear it will go just fine. It otherwise shifts and drives great, I have replaced the fluid and transmission pan/filter assembly as the fluid was also very black looking when I purchased the car. One other small thing I something notice is at very low load and RPM the car kind of surges sometimes as if I was pulsing on and off the accelerator pedal lightly (could be related?). Appreciate any insight you might have. Thanks in advance.
are there by chance any codes present for the transmission?
@@GaryFerraro it has a history code 4F81 EGS ratio monitoring clutch A. I checked all the fill pressures too as follows A=234 B=174 C=40 D=243 E=293 and all rapid fill times are 0 except B=13. All those adaptions were cleared when I replaced the filter and fluid. Thanks

THANK YOU.
@@richyrich5080 Those 2-1 downshift bump, i traced back to either worn bushings or solenoids, On the side of the trans, there may be a number that may begin with 1068, that number tells a lot about this trans, sometimes hard to read the number, the number would have to be decodes by ZF and they may be able to tell what the plate number is.
