CP13

I've been trying to read a lot of information but nobody had confirmed if an engine misfire can cause the VSA/Triangle Light to come on.
After doing a scan, the car only give two codes - P0302 and P1399 but nothing pertaining to transmission (mind that I did the AV6 swap 1.5 years ago). I am crossing my finger that these two lights are not a major issue...

Any thoughts?

Thanks!
