8HP Downshift Problem Fixed: WITH EXPLANATION 

URO parts man... never again for me as well. I just tried to use their valvecover and ended up crossthreading my head threads due to incorrect bolt thread type on the bolts within cover... I feel your pain man. Glad to see you got it working regardless. Definitely wanting to swap the 8HP now seeing yours. Very nice!

Simply brilliant. It is so exciting to see the build coming together nicely.

Amazing what this Lamik stuff can do, looking forward to seeing the new arrival :)

Your clarity is impeccable

Its awesome to see this kind of development and support, I really appreciate when you do the honest reviews. I wonder if this could be implemented in say, a v10 m5/6 or something, that would be a cool replacement to the smg without the hastles and price problems of the dct in a swap.

Thanks for the update guys! Have a great weekend. Dutch regards, Nico.

Im so happy it is kinda smooth now ! And that was a super interesting information about the 8hp and its sensors and calculation, that even I didn't knew! But what I'm also looking forward is when it goes fullspeed, keep it up and thy very much for that insight 👍

Extremely useful video, thank you!

Awsome brother. Awsoem to see!

Big wow. Can't wait for more

Great content

Great stuff. I can only dream about having so much time to spend on my car. Anyway, I'm quite happy with my XHP st 3 DCT gearbox even though I sometime fear for the drivetrain on some of the more violent upshifts 😯

It's so great to watch everything come together the way we all hope it's going to. So cool. Thank you again Andrew for the great content and bringing us all along for the fun! (Pain? lol). Personally I've just come to the point where I've saved up enough money to order my new turbos. I'm glad to also have found a Canadian distributor that will sell and ship everything I'm needing to me with NO SHIPPING COST. It's not even massively absorbed into the price as it usually is. So I'll be getting my new 17T's (Thank you for all the inspiration) and outlets etc along with an "O" ring kit and all clamps and gaskets from the same supplier. My total on this is $1235.00 CAD, all in! (yes I'm quite poor lol. I work running a safe house for men that are coming out of addictions and it's not government funded so... just wanting to give back after my life was changed drastically for the better). It's the best price I could have imagined for the whole set up. Of course I'm also doing the oil pan gasket and I would do the water pump and thermostat but they were done 13,000 KM's ago along with the serpentine belt and all pulleys oil gaskets and vacuum lines. (Sans oil pan). I'm not looking forward to the install as I don't have a lift but I might consider renting one.. Anyway sorry for boring anyone that actually read this but I'm very apprehensive about it all and sharing it here is helpful IMHO. LOL. Any advice is humbly and joyfully appreciated. P.S. the only thing that may be of interest to some is that I'm doing this on a XI car so mine will have the all wheel drive option and maybe be interesting to document some results from that point of view. I'm running MHD, XDelete, XHP as well as Pro-Tool software which I find extremely intuitive and capable of almost anything INPA etc might do.

Cool stuff Andrew. I know you’re going through the move at the moment but it’d be great to get a “state of the fleet” update. What cars you’ve got, what the plan is with them etc. even if it’s just a short or something. Happy Easter

The 8hpis a huge step up from the 6hp. Even with stock tuning it shifts so fast. I had xhp on my e90 and I thought that shifted fast. I got an f15 50i 3 days ago and I love the 8hp already, it shifts faster. The xhp will be nuts on this thing!!!!!

It is very cool!!!!🔥🔥🔥🔥👍👍👍👍

Looking at swapping a dct or 8hp into my 450bhp om605 diesel didn’t realise you had done both conversions which one do you prefer and which do you think would suit my platform bette

Beautifully explained Skip. Thank you

Hey i'm having a similar problem on my chrysler 300 where the downshifts are harsh (sometimes it pops 5-4 , 4-3 but most frequently 3-2). When its cold outside its harsh. When its warm, its fine until it gets really warmed up (180 F for the trans fluid). do you know if I could make similar adjustments, it has a derivative of the 8HP by chryler, the 845RE.

beautiful area over there btw

I have a problem with the transmission of my 2008 x5 e70 (6HP). The Gearbox change very smooth and well but When I accelerate, either to pass a car or going up a hill, the gearbox goes into neutral ( always when downshift from 3rd to 2nd )for no reason and I have to put it back in D to keep going. It does not give any sign of error even using ISTA scanner . (I am not using a generic scanner) We changed the solenoids, oil, filter and mechatronics seals, we made all the settings with the box parameters and the problem still continues. Do you think that could be a parameter problem??? Save Share

Wow thats amazing. The level of detail here is unreal. I have the common problem with judder in 6th on a BMW 330e. You or Lukas any idea how to fix?

Very interesting about shift points thats gonna be handy for rag racing

this is just what i needed on a friday. im scared to break in my transmission next week. i have the pure drivetrain clutches and billet baskets etc etc. they said not to break it in on a standalone but, what option do i have? lol. on a second note, you should just buy the reybestos clutches. you can add an extra clutch in the A clutch pack as well! 1000whp capable all day long with $500 clutches. if you have to open the transmission, youll have to remove all the diff drums anyway. might as well. for what its worth, pure drivetrain makes that billet cog drive and its made to increase oil flow so no more jerky shifts. its expensive but its worth it if youre really going to thrash it.

I have this 3 to 2 downshift problem only when I try to flash Stage 2 or 3 xHP. Stock and Stage 1 no problem whatsoever, very smooth and proper engine braking. But in Stage 2+ the 3-2 downshift is loud/clunky and gear feels loose for a second (and jerks forward) before the engine braking kicks in 😖 I have the 8HP70Z on my 650i. I find it so strange that it works perfectly on stock software.

I've got a Hyundai genesis g80 which uses re engineered ZF8HP having a similar hard downshift and upshift between 2nd and 3rd gears. It's very well maintained transmission but I could not fix the hard shift. What do you suggest I do bro? I replaced the ATF oil and with pan multiple times and changed the TCU with a new one, and changed the valve body and all solenoids. same issue.

I have a brand new stage 1 8hp45 from Pure, and I’m already getting transmission malfunction. 3rd to 2nd was an insane downshift. Sometimes tires would even chirp. Was this an issue from not being tuned. Or can being under power ever be an issue ?

I have my Jeep being diagnosed in the shop right now because of this odd downshift. And I don't think they will be able to fix it. Could I record data and have the program fixed remotely?

My 8hp75z in my 335d is randomly clunking when i slow down in 8th gear sometimes. Its great all the time besides when i speed up to 80 plus ans arouns there slowing down it clunks hard and loud. Randomly it falls from 8th to 6 to 5 (smoothly) but odd like why is it doing that? Its two separate things... the calculated diff ratio is 2.79 but it learns ro be 2.81 as that was recommended... should i change it to set it to 2.79? Using cantcu...

I’ve heard there is a drift mode with lamiks 8hp swap I may be wrong but if so how does that work and how does it perform?

Thx for your vids. All your info is beginning to get thru my thick scull. Most of us DIY's can do the mechanical, we can do the mechatronix - even tho nobody has done a Vid on wiring up the coils on the 8hp. SLG did a vid on wiring up the coils; but that was for a DCT not an 8hp; how different is the 8hp coil wiring than the DCT?. Anyway, you said if we had a prob Lucas could answer our questions; but you failed to mention how to contact Lucas! I have questions, so what was Lucas's cell# again? THE 8hp swap is still in its beginning stages. The Bellhousing Adaptor Plate aftermarket crowd has stepped up; unfortunately, there isnt a knowledgable go to tech line to answer questions.., now, not 2 weeks later or 2 months later. Whom'ever offers a real tech line for 8hp swaps, will own the 8hp swap business.., oh yea - what was Lucas's cell phone# again😊

Did u install the dct or it came with the car

i wonder if some of the clutch packs are fused with the friction discs. i had a 4l80e in one of my trucks was slipping that i just drove home slipping anyway knowing damn well i was just gonna throw another used trans in it (a few years ago they were a dime a dozen) when i took that trans apart just cuz i like taking stuff apart especially when i dont have to worry about getting it back together some of the clutch packs were literally friction welded. it was rather amusing to me. that was really extreme case scenario tho

👍👍

Why it’s doesn’t showing D8 in the cluster, only D when it comes to 8th gear? And in standstill it doesn’t goes to D1 did you prefer that D2

can you share contact to this Lukas guy? I have similar problem on Q7 but with shifting down from 5 to 4

What is the gearbox code for the gearbox that will take the most torque for the N54 engine ?

Hi. Any chance i can get any contact detail, of this huy that helped you ,Lukas? Thanks in advance, Andy.

Are you active in the Turbolamik forum? Iam tom

8hp zf gearbox have solenoid issues by factory. This should stop as soon as possible

Sounds like a pretty smart guy! Shame that some damage was caused by the after market pan 😢

Sad to hear about those clutches.

Don't even talk Htg please 😅. They are just the most headache you can have... Did spend more than a year with them then bin it and went turbolamik

"69 clutch plates"?!
