Two drain fill cycles will replace about 75% of the fluid.
Sadly, I now have a trans problem... it has developed a 5th slam at low loads (around 1500rpm or so) - this seems to be a direct result of the drain and fill. 
Thinking about options - most likley is a mechatronic "rebuild" such as you are doing. |
Yep, that's right - now looking into 3 fill cycles after consulting ChatGPT
. As for your issue, checkout these videos by Gary Ferraro, whose considered a guru of the ZF transmissions. You can actually ping him with your issue and he may offer recommendations. Any trans code thrown?
