How many liters of transmission fluid is supposed to be in the transmission? I can't find any info in the drivers manual. I'm pretty sure there's more in it than it needs and I want to drain and replace it, but I don't know how much to replace it with.

The refill amount after removing the bottom pan is 7 - 7.5 liters. Most technicians put in 6-7 liters and check the fluid level. Once the level is at the "full cold" mark, the vehicle should be driven to get the fluid up to normal operation temperature. The transmission can then be topped off to the "full hot" mark.
