8HP50 Teardown for HTG GCU Install

- On todays episode of the 135i 8-speed adventure we tear down the ZF 8hp50 we are swapping into our BMW N54 135i so that we can convert the internal wiring configuration to HTG specification. We will be using the HTG GCU for transmission control in conjunction with the factory BMW DME. Stay tuned as we reinstall the mechatronics in the next upcoming video. So far so good!

This thing is the pressure reservoir for the automatic start-stop
I like how you guys just dive into what you are doing. Exploration to discover and pass on what you learn.
Best education is experience! Thank you!
Stoked to see development happening with this as another trans option.
Mike's awesome dude. Purchased some items from him, for my e46, and his support is there when needed. Looking forward to make this trans swap to my e46.
Pull the lever up on the TCM and remove the Bridge seal to save breaking it , common on ZF
The 8hp is pretty much in every single new rear wheel drive vehicle. This trans will be like the LS engine of tranmission swaps.
Frist time in my life i saw 👀 bmw transmission valve body ecu hit with hammer 🔨 😋
All zf remove same way haha
Live and learn haha
LOL the way Mike says SOLD-ER
lol cant stop wont stop
What’s the differences between the DCT and 8HP? And what vehicles comes wit the 8HPs
DCT is a dual clutch trans and the 8hp is a modern auto with a torque converter
@@SeemsLegitGarage so which one is better power wise?
8hp has more gears, better for power.
Does the 8hp require coil rewiring like your DCT video? Are the Ryu and HTG PCB the same - if they are the same then the only difference in shifting is in the actual GCU or TCU(?). If the 8hp requires rewiring of the coils, when can we expect that video?
What did you guys figure out to fix the Park pall coming on when the engine shuts off?
Unfortunately with the BMW trans we could only make a parking delete so when engine is off it’s always in neutral. For Dodge we have a parking kit and you can have P or N while engine on or off.
What torque converter is used?
the one that comes with the transmission
@@alexgonzalez7395 no need a custom or modified
Please sell those baffles for oil pan never really seen that in a n54
What car is that transmission out of?
any B58 BMW
How much does the whole thing cost? Parts only?
All of the things HahHa her we have a thing held in with a thing that holds a thing
it makes a new thing!
So will the gcu come with a tune to plug and play to this swap.
It changes per application, we can provide base tunes
@@SeemsLegitGarage do you provide instructions and wiring instructions to install gcu to the n54 (335i)?
@@alexgonzalez7395 You just hook it up to the CAN bus
Can you tell us what is the difference between the 8HP - 45 (1st Gen), 50 (2nd Gen), 51 (3rd Gen)? Oh …. and the 55? (Is it RWD or AWD ?).
mostly valve body updates to make it more efficient and shift faster
So do you guys have a metal oil pan for those 8hp? Or is the plastic cover the only thing thats available right now?
the filter is built in so we just use plastic but we did order some metal variants that weren't too expensive to try, we are going to test fit and then put on site if they are all good.
That "thing" @6:30 is the start stop pump, for when the engine shuts off, it keeps pumping fluid in trans to keep oil pressure in trans. So when you let off brake engine is running and you already moving. The F gens and on have that in the 8hps that have the Start Stop function. From what I recall because the e70 x5 didn't have start stop, the n55 and n63 models that had the 8hp70 and 8hp45 those early ones shouldn't have those pumps in there.
very cool! thanks for the info
@@SeemsLegitGarage yea no problem! Are the HTG GCUs gonna be on your guy's site? Is it pretty much same functions as the Lamik controller?
@@darksidemotorwerks9867 yes they are! They are like the Lamik just a bit more capable, like a motec vs piggyback
In the ZF 8HP transmissions, it's not a pump but a hydraulic accumulator (spring+piston) with a latch mechanism. Function is the same- provide oil pressure to apply clutches for start/stop functionality. Just gives that bit of instant oil pressure/volume before the pump is able to supply.
For a Single turbo N54: Do I go 8HP50 or 70?
It'd be way easier sourcing an 8HP50 than a 70. Worse comes to worse, send it out to PDS for a rebuild
Why did you go with the HTG GCU rather than the Turbo Lamik TCU?
Its much more conjurable, has better support, and way more features
@@SeemsLegitGarage Just getting it working seems to be a major achievement according to this guy czcams.com/video/JdfjIO5zPDI/video.html
@@JACB006 We have sold hundreds of kits. Some people are not good with this type of stuff
ali can say is the cars we work on work sweet. Its not that hard
Is it your first time using HTG GCU?
no we have many customers running it and also our E46 car withe a DCT using it
@@SeemsLegitGarage Are you satisfied? Because in Poland We have tons of negative feedback about it (paired with 8hp, DCT works fine)
@@michaumichauowski5531 about a 1.5 years ago we had teething issues like any emerging technology but it is really seamless now
the htg computer will damage your engine or gearbox. subject widely and hotly discussed in Poland. you will lose time and money. Look for the Turbo Lamik driver. tested and working in a huge number of projects, drift, offroad, or daily.
That is completely False we have many many cars running the HTG system with great success. Its closed loop control and software is far advanced and the only one being pushed forward.
@@SeemsLegitGarage ok ;)
@@SeemsLegitGarage there is literally a class action going on my guy. Bartek is getting down.
