ATF fluid on 2006 Mercedes-Benz CLS500

Should i use Genuine Mercedes Benz fluid when i change the ATF, or use basic Dexron III type fluid, please advise


if you use anything other than MB fluid, you will likely
ruin the transmission. you will need the MB tool that measures the fluid level, as it does not have a dipstick.
