So I did a quick drain and fill for my 07 g35 sedan. I purchased 4 qts of matic s and after i put them into my car I noticed that one was a K Matic.

Do I need to re drain and fill? I can't find info anywhere.

Thanks in advance.

 

You should be fine if it was only one QT, The matic K seems to have a little thicker viscosity but should not hurt a thing.
