IIRC the only major difference is the Differential.

and the gears are different in a n/a trans. so if your cars not shifting right now you need the new gears tuned in the pcm.

That too ^^ haha. Are the sun planetary's the same the same or different?

Good. I wasnt talking about the normal gears, I was talking about in sun planetays, I didn't know if there were a bit stronger in the HD or not
