D4 blink is only trans related. Sometimes it can be minor if you are lucky, depends on the symptoms and what the car is doing. Spend some time searching the site, as you can imagine many people have reported this problem so there is a lot of threads on it.
Did it to me. **** off car and ignored. I got lucky. Mine lasted around 5 more months after that. Then she slammed back into first and wouldnt shift at all.
