the fluid you drain is the trans fluid you should not drive the van till you refill the fluid but you need a special tool to do this the tool cost about $500 so I recommend you toe it to the dealer . the engine drain plug is to the right of that under the engine let me know if you have more questions
i live out in the country and there is no dealer within hundreds of miles. is there no way to refill the trans fluid>
the only way is to pump it back in thou the fill hole but you need a pump and fitting
if you can get some kind of pump then you can just pump it back in thou the same hole
i have a pump. do you know where i can get a fitting?
