ZF 8-Speed Transmission Guide (8HP45) - Specs, Common Problems, Diagnostics, & Maintenance

[@Vanguardkl]

Just came off an Engineering Explained video claiming this is the best auto transmission ever... This is much more useful in the real world

[@jonathangipaya]

You all are crushing it with these videos! Thanks so much!

[@jasoneyes01]

Awesome presentation. I havn't had the joy of owning a Beemer with an ZF 8 speed yet, only the ZF6HP28 6 speed and it has been bulletproof. ZF is a great company with heritage dating to the Zepplin. Reliability is the highest priority.

[@johnwebster8020]

I too have a Jeep GC with ZF8 box, fantastic tow vehicle, dont use 8th gear for towing. I am a little concerned with vehicles with 10 speed boxes and towing, might be keeping the Jeep a little longer

[@H0MEDADDY]

Definitely agree that this tranny is a keeper. I'm a 20 years experienced tech and I have one in my 2013 ram 1500. Not one problem with the trans since buying the truck brand new. I've done one full service, changed the pan/filter with mopar and amsoil ATF spec'd for it at around 75k km, and just drained and filled it every 75k km since. At around 225k km now and it drives like it did on day one. I'll be doing another full service soon with a new pan/filter. Nothing required other than the regular maintenance, not even so much as a leak.

[@4-Runner]

How's the drain plug holding up or do you have to replace it after a drain and fill?

[@H0MEDADDY]

@@4-Runner I kept the original from the original pan when I did the first full service. Haven't needed it yet after any of the drain and fills. Could probably just change the O-ring on it if you find you have a leak after removing and reinstalling. The one thing to mention is it's an Allen 10mm I think, but being plastic it doesn't work so shit hot. Use a torx 45, or whatever size fits best, 50 maybe I can't remember, on it to remove it.

[@4-Runner]

@@H0MEDADDY Thanks for the info. Appreciate it!

[@PoppinPortraits]

Agreed this is the best transmission I’ve ever had

[@JWORLDKING]

Not at all. So for example lets see how good it is after a running time from 500.000 Miles compared to an realy good Transmission like the World best Japanese AISIN Transmissions. For example i owned also a AISIN 5speed Transmission with 4 Overdrive Gears and it runs, shifting like a pure dream fast, very direct absolutely without shiftlegs. And without any oil changing after 6 Years lifetime. Also Hyundai Transmissions are in the Average decent too, but my 5speed of course not that good as my 5speed AISIN in the drive feeling BUT in the quality my Hyundai Transmission is very reliable and very strong. But i guaranteeing no ZF Transmission will by far not gets the same lifetime like a AISIN there is no Arguing that. With a equal, same maintenance no ZF can mess in lifetime with a AISIN. It starts already with that primitive Plastik pan, ground cover on the ZF 8speed As far i know AISIN doesn't use such a plastic crap for example for the oil pan part. But if such a plastic sh... will may eveen come on ASINS i be sure, than are the Plastik parts from the European, German Manufacturers way way more trashi, crappie than Japanese ones are. This is, what it shows in the history allways in that way. So i don't expecting already here a long lifetime and a maintain less payable lifetime from those ZF crap. Thats normally the way, how it is. Regards Jay

@@JWORLDKINGyou cannot compare smoothness and shift speed to Aisin boxes, ZF 8 is number 1 by far. Most used gearbox in the market for a reason. Same reason the biggest brands use it.

I have this transmission in my 2012 BMW X5 35i and it is extremely smooth but yet if you need it to turn into a quick shifting performance machine you can slap it into sport and it transforms it.

[@Vanguardkl]

Thanks great video. From ZF service manual: ZF 5-, 6-, 8- and 9-speed as well as the ZF 4HP20 automatic transmissions are filled maintenance-free with specially developed semi-synthetic ATF oils. However, due to the many factors influencing the service life of transmissions in individual operation, ZF recommends an oil change after 150,000 km for its transmissions. In operating conditions with high temperatures and loads, or with unknown vehicle use in the past, it can make sense to change the transmission oil at shorter intervals. In each case, only released ATF oil may be used for oil changes. And oil changes must be performed in accordance with the relevant specifications. The exception is the ZF 5HP18 automatic transmission which must be filled differently depending

[@fastboatster]

8hp has been in service in the 3 series for 8 years but it came out a lot earlier. First application was in 2008 7 series. Basically came out at the same time gen 2 6hp came out

[@DaveNanan]

ZF is an amazing transmission and shifts very smoothly, and when it comes time to change the pan/filter on my Chrysler 300, I will make sure to get the proper ZF fluid and filter kit! 😊

[@-DC-]

Best automatic transmission in the business.

[@slavric]

My broke at 300.000 km, grooves in one planetary set were torn. It was a common problem and upgraded version of this was installed. It was not expensive at all, together with oil and filter the repair was 1,100€. Now I have 330.000 km and I wonder how many more are there before breakdown. When I first drove this car on a test drive I almost couldn't believe how smooth everything works.

[@Bamsebrakar2011]

I agree the ZF 8-speed is a fantastic transmission, very quick and smooth gearchanges. It was a bit confusing in the beginning where you first very clearly recommend the original ZF filter unit and then later, underneath the car it sounds as if you say you don’t recommend it «because it’s made by Philtrans»…, which is correct? I can buy a kit from ZF or Meyle, where Meyle is actually a bit more expensive. Meyle is a reputable manufacturer, although ZF seems the better choice as the original manufacturer. Also, is there a similar instruction video on actually changing the transmission oil?

[@MarioDallaRiva]

Bravo, Gareth!! Awesome FYI video.

[@Killian665]

We had a 2016 X3 3.5i that went through 2 of these in a month because they would not stop leaking from everywhere. Like they were building up pressure internally or something. Luckily it was all dealer warranty work. Ended up getting rid of it for a Grand Cherokee 5.7 with the same trans and haven’t had any problems with it this time around.

[@ts0874]

In Australia we have the 6HP in our Ford Falcons and it was a reasonably common problem where the transmission cooler failed internally, However I have never heard of a ZF gearbox failing without reason aside from the cooler. I would like to know more about the sound they make on their upshift, I gather its the brief unloading of the engine to allow for a safe/smooth shift saving the input shaft, But I would like to nerd out on more information about this and why it happens, and why you don't hear the same noise in other automatics, apart from DSGs - Which the ZF isn't.

[@chadriddle3517]

Hi Steve, I have an F32 435 AT 8 speed, Quick question when you put the car on sports plus and on manual mode, and you floor the throttle from gear 1, does your car go into overrev or does it automatically shift up to second gear?

[@SteveWeltman]

@@exoticsinafrica1789 it auto shifts from 1 to 2nd even in manual at WOT in full sports mode. That’s by design from ZF software.

[@exoticsinafrica1789]

@@SteveWeltman thanks for reply, my car doesn't auto shift from 1st to second when im in sports plus mode or with DSC full off,with manual gear selection selected, instead it went into overrev and power cut, does that mean I have a problem with the engine or gearbox? Im perplexed as i bought the car used about a month ago?

[@SteveWeltman]

@@exoticsinafrica1789 unless you have XHP software it’s hard to know if there are adaptations programmed to dis-allow auto upshift. I have a bone stock ZF6HP21 in my E90/N54 MSport and it forces a 1-2 shift at WOT w/DSC and traction off, full manual mode. The over-rev may be allowed by software in XHP or it could be regional if you’re in EMEA (you appear to be). Either ProTools, XHP or a transmission pro can further explain well beyond my limited visibility on your cars conditions.

Worse when the temperature is below freezing... gets better when the engine is hot and even better shen the weather temp gets higher... Difficult to set into Reverse - have to put it into Drive mode first and then Reverse... When I start drive the rpm goes higher before shifting, and 40 miles an hour with 3000 rpm, does not get the transmission to shift... It's like only the first 3 or 4 gears are being used... Manual gear is not possible... One day is totally crazy - the next day it runs without any issues... Yesterday the oil level was checked and was ok - the oil was dark but not black.. not clear... The car has just turned 100 K miles.. I drove the car to a workshop specializing in automatic transmissions, and they said worst case scenario is a new transmission....

A question to Gareth and the Community: I had an appointment at a ZF service point to flush and change the transmission oil of my ZF 8HP45 after 85k km. My F20 is changing gears like a brand new car since then. However, when the transmission gets hot, it starts to smell quite badly via the air vents. This issues occured right after the oil change. After two weeks it is not gone yet, althoug it has improved slightly. The service staff double-checked the transmission. No leakages were found and no oil was outside the gear box. They told me, it is quite common that the F20 or F10 series from BMW tends to smell due to the fresh oil. It should stop smelling after a while. Have you experienced something similar so far? Thanks.

Hi there, my wife's 2015 x3 28d had a drive-train malfunction last Saturday. She came of the hwy and as she was turning right the car jerked twice and then lost power. She pulled over and shut it off. Waited 5 minutes and restarted it. Motor was fine but she could not select gears just stayed in park. Now it got towed to Kingston BMW and they diagnosed it as it needs a new transmission at 15k plus 2500 labour and taxes on top of that. Now the car has never showed any transmission problems until that day. I tried to find out from the service manager to see what part of the trans is faulty but he refused to tell me or they do not know what exactly the problem is. I also requested that he sends me the diag results which i just got today after complaining to BMW Canada about the situation. I suggested there must be another option because i do not have 20k to spend. I bought the car last year in January with 136k kms for 20k and in August the egr cooler caught on fire and the car was at Otto's BMW in Ottawa for the whole month of August. Which they had to replace the whole top-end of the motor because of the damage from the fire. Which BMW covered 100%. Now 8 months later the trans goes out. I kept on asking the service manager to see if there is another option like replacing the part that's faulty or rebuilding it. He just kept on saying the test says the trans have to be replaced with a new one. He also mentioned that they cannot code a used trans because i suggested that and he said they tried one last year and they could not code it so they had to put a new mechatronic unit at the customers expense which was 6k. As of today they still did not tell me what exactly is wrong with the transmission. So i finally got the diag results which is 11 pages. Not sure if any of you guys know how to read them. www.bimmerfest.com/threads/bmw-x3-drive-train-malfunction-impacted-ecm.1397545/#post-13547229 Any help would be great. I can post the PDF here or maybe reply to this comment if you would be able to help in finding out what could be the issue. I have worked on cars all my life built motors, turbos and worked mostly on manual trans but i have no idea on all the new electronics crap. I ended up towing the car back to the dealership where i bought the car which is not a BMW dealer and they said will have a look and see what they can do. I did buy a 3rd party warranty 48mos or 80k but there is a 3000 dollar claim limit. Cheers and thanks for your time Lester.

I have a “transmission is too hot warning sign” when push hard on highway. Where should I be looking for this issue?

[@Lui8111]

Check your fluids at the proper temperature for tranny I believe it’s 86-122. Get an oil sample and pay to get it examined for coolant leak in tranny. ..when checking tranny Don’t let it get past 110 bc it takes forever to cooldown good luck

I got similar issue too on my F25. did you sort it?

[@Lui8111]

If you’re out of warranty and you can’t check your transmission you should read up on how to do so. The reason I say that is because my 8HP 45re transmission Doesn’t have a dipstick so I have to do an additional step to get an accurate reading but if you have a warranty take that thing and don’t mess with it

Hy Gareth, I have an issue with my ZF 8HP, on a BMW x3, G01. When the car is stoped in traffic, when I start the car a kind of whistling noise is coming from the gear looks like. Is like an internal hydraulic oil leak or something. The sound is similar to a ship’s whistling! What do you think it might be?

Will Sasso does transmissions !? Excellent!

Once we saw him in Super Troopers 2 we knew we had to bring him in for DIY work.

Please, tell me why my audi rs7 2017 performance transmission is rough in sport mode and sometimes just sometimes in normal to its acting sometimes weird.

Hi, really appreciate the video, is there a manual process of checking the oil temperature? Also how much oil does a 520d 8 speed tran takes.

[@Rudeboi0427]

Hey there. Coming in late, but I have a question with a Charger 8HP. Could oil getting into the electric connector cause an issue like a gear change hanging? Meaning it feels like it goes into neutral for a second before going into the next gear. I've been coming across that lately and Dodge doesn't seem to be fixing it. Thanks

I have BMW 520d ZF 8 HP 45. The solenoids had Changed six months ago with the new original parts and the shiftings are now almost good. But when the car gets the second gear and then Just when I take off my foot from the gas pedal, after I take it off , the car shots to the front like I brake it. After the shifting if I continue to the gas 2-3 seconds and then getting the gas off, not just cutting off the gas after the shifting it doesnt do that. the revolution counter shakes a little But it does it when the car is hot, when I drive the car about 30 minutes. Thanks. What can it be. The turbine is new.

Ok so I changed my battery yesterday to a interstate battery yes I know it’s not Bosch one. But regardless after taking it from the shop and driving it a good while with ac on after a while that same day I got a “transmission overheating” please help!!! What can I do does it have anything to do with changing the battery?

[@emaluc95]

Hi! Could you gime me an advice about why it could do a bump between 2nd and 1st gear when breaking for a stop? I have this problem on a BMW 520d GT The car has over 370k km and i don't know anything about it's service history...but i just changed the oil and filter and the two o rings. I've been scammed by some private seller with fake service history and milage cut down
