Hey guys I am tooling up to do the fluid changes in our 2011 X3 35i at 148k KM it is 4wd and came with GA8HP45Z transmission (same as ZF?). Read this entire thread and just looking for guidance as far as tools needed, pictures? what is the Schwaben tool? metric allen key? There is a youtube vid on changing transmission fluid on an X5 E70 would it be the same as our X3?
