It calls for 5w30 I filled mine up to the fill hole then pulled the shifter out and put a quart of Lucas oil stabilizer in it. It shifts good and is really quiet. I heard you should add the extra quart so I did the lucas

Rather than pulling the shifter out isin't there another way of adding the additional quart beyond the fill hole? I thought someone mentioned going through a PTO bolt. Am I missing something?
