I doubt the ATF you put in is causing your troubles here.
What are the DME and EGS trouble codes?
What are the DME and EGS trouble codes?
Is ISTA+ "high level" enough? Ista shows 0 faults for DMETwo thoughts; neither is likely to be solved with a fluid change.
1) Your car has a torque converter that has the locking feature. (?) It's not functioning correctly?
2) Your idle valve is not keeping up with the engine speed when going from P to R?
Do you have a higher level scanner? I would pull codes and look at a few things with the DME (engine computer) and the EGS (transmission computer)
When I changed the whole transmission. The bmw workshop told me to reset adabtions.Wild guess, sometimes when you change/refresh fluids it's a good idea to reset adaptations. Could this help?

So what can I do?DDE swirl flaps are an issue that will need attention at some point, but not your issue currently.
Adaptations resetting is something I'm ambivalent about. However at the end of the day, it's really just fine tuning of how things run. Think of it like adjusting the bass and treble on a radio.
Adaptations will not make a EGS or DME not perform the basics correctly.
I can see the status of them with ista yes. But I have no idea how to read the data. It says solenoid 1-4 I think. They are ON and OFF also I can see torque coverter clutch status. But what does off mean and on? When are they suppoused to do anything? Etc...Just a guess, but knowing the status of these things can answer a lot of questions.
I started with transmission issue yes because after I changed the transmission it all started.So the locking torque converter should only be working in 4th and 5th (year model variant dependent) gears.
I'm just wondering if your engine stall is the converter locking when it's not supposed to.
All of this is just a guess. You started the conversation with a suspected transmission issue. Could be something else entirely.
Thanks for sharing your experience....only use Dexron VI that is GM certified. I used a fluid from an otherwise reputable manufacturer that claimed to meet Dex-VI for a couple of drain and refills. Everything worked fine until cold weather hit.
I would say no thank youDefinitely use Dexron VI. In addition, only use Dexron VI that is GM certified. I used a fluid from an otherwise reputable manufacturer that claimed to meet Dex-VI for a couple of drain and refills. Everything worked fine until cold weather hit.
At first I thought my trans. was failing because it kept slipping until the engine was fully warmed up. After some hits and misses, I decided to flush it with a fluid that was GM certified. Since you can only drain about 40% of the fluid without opening the trans. I used 4 drain and refills (run in between), which replaced about 87% of the old fluid. Totally fixed the problem. (There are other ways to flush a trans. but I went lo tech.) If you need to go further to get rid of the Dex-II six drain and refills will replace 95% of the old fluid.
Take home lesson--Use Dexron-VI fluid that carries a GM-certified label in AS360/390 trannies.
Hope this helps.
I bought it, I installed it. I have been working on cars as a hobby for many years and I have installed many automatoc transmissions on VAGs. BMW is new world for me.Did you take this car back to the shop that installed the replacement transmission?
It seems they should fix it.
Ah ok, it wasn’t clear who did the work. So, you are the shop.I bought it, I installed it. I have been working on cars as a hobby for many years and I have installed many automatoc transmissions on VAGs. BMW is new world for me.
Why would I go to shop and pay 2500€ for automatic transmission change if the car is worth 1000€. I can do it myself. Google is full of tutorials how to. Why not do it myself🤭
Transmission was used and seems like it was already broken somehow. But old one was alot worse.
Today I finslly got transmission into limp mode😅
