I recently purchased a 1994 ATX Sho Taurus with the legendary Yamaha 24v Dohc Sho V6. This is my first car at the age of 17, and I was thrilled, until the transmission went- Sparratic shifts, harsh and uncontrollable. At first, I assumed it was the speed sensor or throttle position sensor, but I replaced the VSS and still no change.

I was already thinking about saving for a trusted blazer or some truck that I could find around for cheap. My father wanted to change the fluids, which were all recently changed along with the car's 120k maitences including new valve shims. After changing the transmission filter, we found an inch by inch and a half piece of hardened steel, a piece of one of the clutch pack's bands. This explained the slipping in a heartbeat. We added only a quart of Lucas, and the transmission was at first only smoother for the first 20 miles, and then suddenly, it was fully normal, and soft shifting at low throttle. Amazing, and my father, an ex Ford mechanic stated that he has never seen anything like it. I have a couple hundred miles on the car with 2 quarts now in the transmission, and it shifts perfectly. I plan on using Lucas oil products in every vehicle I will own as a preventative action. Clutch in a bottle.
