C5 6 Speed
i recently replaced my transmission oil with Royal Purple Synchromax, as suggested by several members. I immediately noticed a transmission "howl" primarily at highway speeds.
i am a new owner and have almost no experience with this car's mechanics. Is this normal, serious or maybe just coincidental?
