So before I went on my little road trip last weekend I dumped a bottle of that Lucas Oil Tansmission Stop Slip stuff into my trans. Biggest mistake I've ever made besides the interest rate I agreed to on this truck! From the second I put it in I was worried I wasn't going to be able to take my truck on the trip. If I thought my tranny was slipping and hanging in gears at high rpms before, oh my god. It really has never run this bad. It not as bad now almost a week later but it still isn't shifting like it was before I put it in. Has anybody else had this problem with that stuff? I was really surprised at how bad the trans ran.
