Hey guys I am having a little trouble with hard 5th to 4th downshifts using the paddles in drive. Doesn't do it every time but when it does it feels very harsh. This is my third G37s and others did it too. I have 28000 miles and wondered if changing to synthetic fluid would help? Any one else have this problem?

 

If you have a G37, I would suggest you head over into the MyG37 forum instead.
We're all just a bunch of old farts with 35s
