yeah, best off taking it somewhere for the transmission. I dont have any experience with FWD transmisions yet as this is the first vehicle I have had that was FWD setup vs RWD/real 4x4. Anyhow, lots of experience with normal RWD transmissions. With those, just draining or dropping the pan and refilling typicaly only gets about 1/3 of the fluid, as a lot of it is still tied up in other places like the torque convertor. You can take things further apart and drain/refill the torque convertor and all that mess, but this is one of the rare things that is really not worth the time and effort to do vs what it costs for a shop to hook it up to the machine and more or less do a transfusion with it running, no matter how hard core of a DIY'er you are. This applies to automatics of course. manuals are a lot simpler with just a simple drain and refill. Same with transfer cases and rear difs too, but again, no experience yet with the FWD setups so might be different.
