BMW G20 ZF 8HP Transmission Service | ECS DIY

In today's DIY, we show you how to service your ZF 8HP automatic transmission in a BMW G20! We begin by removing the undercarriage covers, lowering the transmission crossmember, draining the transmission oil, removing the transmission pan, replacing the transmission pan, torquing the bolts to spec in the correct order, filling the transmission with oil, cycling through the gears.

Interested in more G20 M340 related videos.
Also, on the ECS site it doesn't show this kit as compatible with any G20 models.

Great video! Now I know how to pronounce this stuff I've been buying for 20 yrs!😅

I've seen multiple videos on this and not one dropped or removed the transmission cross member brackets.

What is the connector socket and why mess with it? Never seen that mentioned in any other fill vids for this transmission.

how with the bmw 530e, 545e plug in hybrid it has no torque converter is the oil change different with less oil

Thank your for the video. Just to give you guys some feedback, in the EU, Meyle produces one of the lowest quality parts from all the OEM or OE producers out there, at least for BMW.

ECS tuning, if you manage to get one of the charged hybrid ZF8 and/or mild hybrid ZF8 transmissions on your table, could you show us in more detail what they have that is different from each other and what is similar and can be interchangeably used?

I have had a wish to upgrade my MHEV to PHEV. From what I understood, the 4th gen ZF8 has 15 kW electro motor inside to help with the stop-start and with the initial vehicle movement at lower speed. But since the MHEV and PHEV follow similar logic, hypothetically speaking, one could use the PHEV ZF8 or just switch the electro motors and upgrade batteries in the vehicle to get an improvised PHEV.

I am aware that such task requires comprehensive knowledge of more than just transmission types, compatibilities and their mechanics, but also wiring, electric engineering and software engineering. But for now I would just like to see what are the differences and similarities between these two models and if upgrading one to another might be doable within margins of effort and time considered reasonable.

There should be a class action lawsuit against BMW (& other manufacturers) for saying that the transmission fluid doesn’t get changed because that’s total crap (like my transmission). My 2009 BMW 1 series 128i convertible has transmission issues and only 116k miles. The previous owner never changed the fluid per BMW and now it shudders in 4th & 5th gears when I drive it in full automatic mode. If I manually shift it drives fine with no shudder.

If there has been a schedule to change the fluid and the previous owner had it done this most likely wouldn’t be a problem. Now I’m screwed with a transmission that is not going to last very long. It’s a crime to not have a schedule to maintain it. I read up on this and found that there is no coolant flush, or trans flush, or diff flush or fuel filter that is scheduled by BMW. That’s criminal on the part of BMW. No wonder BMWs have so many issues. I’m sick of auto makers misinforming customers on these maintenance issues. BMW should be forced to either replace transmissions that have issues like mine or replace the entire car. Won’t ever buy another BMW ever again. And good luck selling my car without replacing the transmission!!

When you released the gearbox subframe, what was the gearbox hanging off? The transmission bell housing via the engine mounts?

My question is, when you change the oil like this and don't put it on a machine to pump it out, do you get all of the old oil out of the system?

[genv]

Is it necessary to add any type of sealant to new oil pan?

[JXiong-zoig]

How much would this run at a dealership?

[SuperBikeJoe]

Can you change the transfer case fluid on these cars?
