Justin Jones uses Lucas transmission fix in Infiinity G20

My girlfriends Infiinity G20 had a real bad problem with the tranny. It was slipping so bad it felt like you were on ice it wouldn't want to move when you first step on the gas. I put about a forth of a bottle of the lucas tranny fix and it never slipped once when i drove it. I went ahead and changed the fluid and put the rest of the bottle in it. It shifts better than it ever has!! I never used to believe in additives, but this is an additive that i would reccomend any one to use in anything!!!!
