How do you check the fluid level in the DCT tranny. I've looked for write-ups but am striking out. HALP!!
I'd guess your fluid level is low due to a leak.

You need to get to a dealer ASAP! BTW, the transmission oil is $30/liter. I was told it takes 10 qts! The initial fill is good for the life of the transmission, but in your case, you need to repair the leak and restore the fluid level. Hopefully it isn't too late!
