I rebuilt my ZF9 by just watching ur video and it turned out great 👍
I might have to do the same would you recommend that route? my TLX is at 112k miles
The engineers who design a transmission with all these parts are amazing. The people who can take it apart and put it back together are also amazing. I can see why they just replace them now.
How we have managed to make so many pieces of different materials at different shapes and thicknesses work together so effortlessly is beyond amazing
Well done and well explained
Greetings from one who developed this transmission at zf for many years
is this transmission really reliable because it uses dog clutches?
Argental Griller thanks for this smooth running transmission. I got one in my Jeep and i appreciate this transmission i like how it runs and after watching some of this in depth rebuild i am very pleased to see actuall gears and not belts on pullies definitely a keeper 🤠
That was incredible. Very specific detail. Great angles and lighting. Fantastic video.
Thank you very much!
Excellent video. Thanks for sharing.
Amazing! How Engineers came up with such amazing designs and so many moving parts to work efficiently is simply mind blogging.
If an engineer can reinvent the wheel they will just because never credit an engineer. They will change it up again even if it works perfectly😁👍🤠
Very good overhaul, in Argentina the Fiat Toro and Jeep Renegade have that transmission.
You do one of the best jobs showing it all and making it simple explaining as you go along. I think your a wonderful mechanic to spend the time and setup as u have iv built many of my own transmissions most come out well last one was the old 48re in a Dodge ram deisel defanatly needs lots more cooling than the zf 9 does difference in vehicle size and weight being pulled but this is setup like an Allison impressive. I will be pulling one to build in 20k miles 2016 jeep remagade been a reliable vehicle period want to put a Cummins 2.8 diesel in front of it.
Follow-on here; the 3-5-R steel used to compress the C Belleville spring needs to be the smaller of the two listed in references like WIT, which they show as 6 3/8 ID, P/N 45126B. The other suffixes are shown as 6 3/4" ID, and that's too big to fit in the inside diameter of the piston. Not all of us have shops with parts laying around. It cost me a few bucks and some time to find this out.
I taught myself how to rebuild my 96 Tahoe transmission. When I first her about this thing. I didn't want to look at it. Then I saw Weber show how it shift through the gears. I'm not afraid of it anymore.
Excellent work! Really enjoyed watching this. I’m getting a code P0713 which is the temp sensor for the transmission fluid. Seems like that’s inside the valve body. Do you have the wiring diagram for the 22pin connector that is in the oil pan. I wanted to check resistance valve for the temp sensor before opening up the pan. 2016 Acura mdx 9sp ZF transmission. Much thanks!!!
Id love to see the vacuum testing and tools involved.
Great Video as always! When testing the solenoids are you applying 12 volts to the solenoids? By the way your solenoid testing tool with regulated shop air is awesome, i would like build one. Thank you for this great content. I love working on ZF's
Thank you for this info. I was wondering y the hard shifting.
Awesome video. I wonder where is the stator shaft? Is that in the driving clutch?
very detail video,and very helpful! Would you please send me the special tool part number for overhauling the transmission?
It is a great video. I am looking for a proper repair manual to rebuild the transmission on my car, do you have any recommendation?
Very interesting thanks a lot ! Like you've said in the comments section, the oil shouldn't be replaced as it is considered "lifetime". But does changing it would expend the lifetime of the transmission? If yes would it be better to flush it or you just drain/fill ? Thanks a lot in advance.
Thanks, Sean. Hey, could you do me a big solid here and let me know if that 3-5-R pressure plate from the 6L80 that you used to compress the C clutch return spring measures ID of 6 3/8 or 6 3/4? The part reference I'm seeing shows both. I'm a DIYer on a budget and I'll most likely have to buy the PP. Thanks
Really would have liked to know how to fix the #1 problem with this transmission of "insufficient wire crimp in harness" that caused the recall and makes it shift into neutral while driving during this detailed and in-depth video. Probably would have thousands of views...
bravo for this wonderful video where we understand everything.
Do you have the reference of the hydraulic pressure sensor (in yellow 46:38)?
Thank you very much.
Cordially.
Congratulations for the video, I have the same transmission as yours, it jerks from 4th to 5th gear when warmed up, can you give me a tip on this diagnosis?
Hi there, What happened with the oil pump portion of the video?
Professional video . lots of useful details .
In my discovery sport the gearbox computer has broken. Has anyone tried to replace the ecu zf9hp48 code Q 01-T1 with Q 02-T1. And what do these codes mean?
Out of interest what would happen if the retainer from the torque convertor clutch valve (51m 22s) no longer "retained" - would this potentially put the gearbox into limp mode and would reverse still work?
Thanks for this great video. I have a question. Where did you get the case gasket? Thank you.
The aftermarket is making kits. This link is from transtec, which most suppliers, like transtar1.com can get.

Very detailed and informative video. Thank you very much for considering the camera angles for the viewers . I have been looking and asking for quite some time without being able to get any real information on the subject of modification . This transmission is rated for 350 lbs torque and I would like to know if it is at all possible to increase that number more into the neighborhood of 400 to 450 . If it can be done what else would have to be done for things to work properly ?
I’m sorry but I don’t have any suggestions for you. That trans is so software dependent that I’m sure having the ability to tune the software would be necessary. I don’t know of any aftermarket parts available either that might be stronger
@@siuautomotive HP tuner claims to have the ability to tune the transmission but Im not sure of how successfully. In your opinion do you think that it will handle 310 to 320 ft-pnds reliably without any real changes ?
I might be able to see if I can pull a zf9 tune this next weekend. I think with the correct torque management it could hold 320 ft lbs.
You are so awesome dude I really appreciate your willingness to help with this .
I have a 2018 Pacifica with one of these, and it's interesting to see how things work. I'd be interested to find out why so many of them have had very hard shift problems, like mine. If you slow down to low speed and then give it gas there will be a hard slam into gear. The dealer says it's a "software problem."
Whoever designed this thing deserves a medal!😮
i have a honda crv 2018 diesel engine with that transmission, how can i know or measure the right level when replacing the fluid? do you have a separate video for changing the fluid of the transmission? because i think the dealership put to much in mine and did not check the level of my transmission fluid. thanks in advance,,
Is this transmission identical across the car companies that use it? like can the C200's fit the Compass?
2nd Q: Is it bulletproof?
Is that a transmission fill plug by the big round multi pin connector?
Hi I have a ZF 9 speed transmission fitted to my Land Rover Discovery sport and am having issues when changing Up from 4 to 5 But only when cold ... when the engine reaches temperature the gear change is fine...... struggling to find any advise re way forward. had a software update that made no difference...... what's next? transmission oil change? rebuild? new gearbox/ any advise would be appreciated thanks in advance
Hi, I have a code p0713 which is for the temp sensor in the transmission. Any ideas?
5 minutes in and this shows more information than what Honda ever gives us at the dealership. Comparing this to the new 10 speed, I hope the new 10 speed gives us a lot less headaches.
Thanks! The 10-speed is an impressive unit. One day I’ll go through that trans, because I have a few on the shelf. One of the next units I’m going to cover is the 6-speed because those are finding their way into the transmission shops.
Hello. I want to buy a Jeep Cherokee 2014. Mileage 45,000 miles.
Exactly the ZF 9-speed transmission. is this box a problem? What breaks most often and when? Thank you
I'd like to know the name of the tool used in the dog clutch.
What causes the hard upshift problem? 1-2 and 2-3?
I have a diesel renegade with this gearbox. When stopping at a traffic light do you recommend putting on N or keeping on D?
In D the car gets a lot of vibration. Apparently it relieves transmission by placing the N.
I’d keep it in drive. My guess is that the mounts aren’t doing a great job of damping the engine pulsations.
Where is pressure switch located on this thing?
Do these transmissions always come with a metal tag or engraving with VIN number? or is there just a white sticker with the part number only?
All the ones I've seen have a metal tag, but I don't think it's the VIN. Just a serial and model number. I'll have to check though. Honda typically puts their vin on their transmissions, but I don't think it's on the ZF.
at 2:05 does anyone know which of the two holes to which the transmission cooler lines go to is the source or the return, the upper or the lower? Based on 17:11 the upper hole is the source, and lower the return. Just want to confirm
Why does this trans jerk or buck in 2nd and 3rd gear in the Cherokee
Hi , thank you for posting this great tutorial , I’m am experiencing harsh shifting from 2nd to 3rd on my evoque it also appears to hold 2nd in higher RPM until upshifting , i am a technician so I’m looking to try and rectify the problem if possible , I have taken it to Land Rover and have checked for software updates and had the addaptives relearnt . I’m being told to change the oil next but there is a bit of confusion over the spec as the LR023288 is equivalent to lifeguard 8 , ZF appear to recommend Lifegaurd 9 . Any help or advice would be gratefully received.
I do know that dodge uses the same fluid for the 8 and 9 speeds. Regarding your hard shift, they have issues with the c clutch return spring snap ring popping out of its groove. That clutch is used in 2nd, 6th, and 8th. I wonder if it’s not allowing the c clutch to return as it’s released and cause a harsh shift? If you have two hours to burn, I have another video going through the theory.
@@siuautomotive thank you for your reply , I have watched you other video tutorial which is excellent and very in depth , it is very hard to find anything out about this transmission in the UK , is it possible that the fault could be caused by a sticking/ dirty proportional valve or as you have suggested more likely to be in a clutch pack , there are no errors in the TCU , what controls the blending between the gears ? so is this likely to be a problem with clutch C not disengaging or could it also be clutch B not engaging correctly . I would be grateful for any advice you can give me 🙏
A mechanic from the ZF representative in Poland said that ZF does not recommend ZF8 oil for the 9hp48 gearbox. Therefore, the Zf 9 was created to prevent gearbox failure. Apparently, the ZF8 was foaming.
Use Honda/Acura 3.1 ATF Fluid. They have extra additives to help with smooth shifting
What's your take on using alternate fluids in this transmission such as valvoline max life or amsoil product instead of the 8-9 speed fluid
The best fluid I've found to replace all trans fluids is the John Deere hi gaurd low viscosity hydraulic fluid it was designed for gear box applications such as this and is a much better fluid both for wear and clutch engagement remember jd uses friction and steels inside for not just clutches but brakes as well it is a much better fluid but I have never used it in a zf 9 I have in 48re Ford c and several others wonderful success but not tried in the zf9 yet.
Hello!
I bought an old Renegade 2015. Changed the transmission oil 1000 km ago mostly because of how old the oil was.
Car runs fine than ever, but now I'm getting a leak on the outside of the transmission that I can't found where it's from.
Do you have any suggestions?
Are you sure it’s trans fluid? You could put dye in the trans and use a fluorescent light to see where it’s coming from.
Hi, I’m in Ireland and I am looking at a Honda CRV 1.6. Twin turbo diesel and it had this gearbox, can you tell me if it’s a good or bad gearbox?... many thanks 🙏.
Well, Honda has had better luck with it than Jeep. The manufacturers are responsible for writing their own software for shift timing and shift quality. I know that Jeep has many software updates to improve the shift quality and Honda doesn’t have near the updates. That kind of tells me that Honda is better at figuring this transmission out. I will say that I think Honda is using this trans as a stepping stone until they get their own 10-speed perfected. My assumption is that in the future, most Honda’s and Acura’s will have the 10-speed or a cvt.
I wish I knew someone who could overhaul my zf9 transmission.
Would a transmission update help with weird shift patterns ?
I think Honda and Acura tuned it further to make less crazy (sort of)
What about Updog Clutch?
Here in Brazil, these boxes are problematic, especially on Land Rovers. Here at the workshop I changed the oil in one and it subsequently developed a defect. I suspect it could already cause the defect and I just anticipated the problem. They stop moving, the customer starts/stops the car and it starts working again. I've seen Land Rover recalling this transmission even though the car is not under factory warranty.
Hi, great job! I have sometimes hard up swifing from 4 to 5 gear. No others issues. What could be?
First thing I would have the dealer or a good shop to check to see if there are any software updates. They've improved the software quite a bit on these, especially on the earlier vehicles.
1st, visit the dealership to see if there's any software update. If you're outside of your warranty, this is going to be an out of pocket expense. Another thing we've discovered is a dirty throttle body can cause harsh upshifts due to a need to reduce torque when shifting into the overdrive gears (when looking at live data, anything more than 5-8nm force on the throttle motor is excessive)
Design-wise the 4-5 and 7-8 upshifts involve releasing a dog clutch and applying a friction clutch. The ideal shift is to overlap the apply and release timings to have a smooth transition. However with dog clutch release, if the timing is even slightly off there will be either a torque “bump” or a torque “hole” because of their on/off nature.
Can anyone tell me the name of the person who did this video?

I recently changed my gearbox and tcu,but the drive and reverse light keep blinking the car does not move
I’m sure you’ll need to get it programmed if the tcm is new. If it’s used, it’s detecting a mismatch. Either way, there should be a code stored.
Bonjour besoin d'aide ou des conseils, je recherche un calculateur de boîte de vitesses automatique pour range rover évoque 2014 motorisations
RANGE (LV_) 2.2 D 4X4 (150CV, 110KW) le problème que j'ai eu la batterie elle, c'est fissurer il y a eu des gouttes acides coulée sur le calculateur de boîte de vitesses automatique, il a endommagé les composants du calculateur, je vous mets les photos ma question es que c'est réparable où il faut changer le calculateur de boîte de vitesses automatique. Je n'ai pas la référence du calculateur parce qu'acides ont attaqué le plastique couvert où il y avait la référence.merci m'aider svp
I didn't see any other comment about no video at 19:00 to 19:40. The arrows are visible, but just a white screen. Otherwise great video.
thanks for letting me know. I think what happened is that I had a still picture in there and my video editing program didn't want to render the image when making the video. Unfortunately there's no way to update a video that's already been published (at least none that I know of). I did write an article on this transmission and I cover the pump info here: gearsmagazine.com/magazine/zf-9hp48-a-mechanical-marvel/
Ram claims in the new pro master you never have to change the oil. What are your thoughts?
Unless it’s driven in “extreme” conditions, I agree.
Hi @@siuautomotive Is "extreme" considered stop/go in the city? Also, if you drive less the 5K a year in those conditions, would you recommend a drain/fill at 30/60/90K Miles? Just one last thing, you showed the magnets, but I think there was a metal mesh filter there too, is that ok not changing it with that low mileage for 10 years (say about 65Kish in ten years)? I'm sure to replace that filter would cost a lot with these, it's a lot of unnecessary work to get to it the way they designed the filter internally, let alone the drain and refill process with the Honda Pilot ZF9 version. Thanks, great video!!
Does anyone on this blog know the parts from 2016-2020 ZF 948 are interchangeabe as a full set, thus can be swapped from one case, say a 2016, into a 2020 case?
I am particularly interested in Jeep. And, what model year is the trans in the overhaul video?
I think as long as you swap among Jeep parts, you'll be okay. In talking with the ZF trainer, he says that all the Jeep cases and internals are built in the FCA/Stellantis plant in Indiana, whereas all the Honda and Land Rover cases and parts are built in the ZF plant in South Carolina. I've had them both apart and side by side, and other than valve body, they all fit together and appear the same dimension wise. You can tell, however, that the parts are casted differently.
@@siuautomotive I''m wondering if a 2.4l or a 2.0l engine transmission case excluding bellhousing is same as 3.2l, with the bellhousing serving to adapt the tranny to different engines. Also, if all 948TE have the same set of gear ratios and clutch packs, in other words a "universal" internal hard parts design, very good for manufacturing efficiency. I notice the 2.4l and 3.2l use the same valve body part number. Are different engines then managed by TCM so they can use the same tranny internals? What is your observation? Sorry if i seem to belabor the issue, but better to measure twice and cut once, as they say.
Is there an average amount of miles befire these break
I’m not to sure. They are still rather new.
@@siuautomotive have you fixed alot of these lol?
Hello~ My 2019 Civic Diesel 9AT just reached 20000 miles and the shifting is problematic to me. The issues are: 1. Shifting from 1st-2nd is usually hash & pushing hard even mild throttle 2. Very weird when the car shifts from 4th-5th gear, the car often "hard engine brake" when mild accelerating and everyone's head will dip. But this will not happen if accelerating rapidly. I am going to bring it back to Honda for further checking but I am afraid they will say "unable to replicate the issue". so worrying
except the above issue the shifting up & down through 1st-9th gears is OK especially when accelerating rapidly, it's smooth. But when it comes to low speed + stop & go city area, it's really painful. 4th-5th gear is driving me crazy.
And Thank you very much for the video. Very informative.
I have the exact same car and same transmission. For me it shifts hard when going from 4th to 5th when going slow. If you drive at 42 kmph, it is the worst manifestation and you hear a loud click or hit.
It started around 30k km.
It was under warranty and they replaced the oil, battery (!!). It did not help, as the issue remained. They told me it is normal shifting for this transmission ZF9
Regarding replicating issue, this is what i found:
1) gear box has to be warm, so drive for approx 20-30mins
2) slowly speed up from 30kmph to 50kmph and at 42kmph the jerky shift will occur
3) engine rpm will be around 1700 when it happens
let me know how you sorted it out. In one other video, they replaced the pressure sensor: ua-cam.com/video/MM40QLo5E5M/v-deo.html&ab_channel=TimLampe
Are those a 300000 mile transmission
Hmmmm, probably like 150,000 mile transmissions…
Can it live 200 000+ km if change oil? Car - discovery sport 2020
I think so!
Mechanical reliability doesn't seem to be an issue with these especially on late models. Just keep the fluid freshened up once in a while.

Do you know why these transmissions hard shift between 3 and 4 gear? If so, make a fix it video for real! 👍
What year Acura is this one from?
I believe it was a 2017
Only thing that makes sense to me is transmission
how do people come up with this shit
